Domestic and vacuum equipment

Domestic and vacuum equipment
Some say the most durable German vacuum equipment, vacuum equipment, the most beautiful of Japan, South Korea, the most tangled vacuum equipment, vacuum equipment China's most ugly. In fact, many people do not find the same configuration for domestic and imported products at the same price or contrast ratio, the heart inside the moon always kind of feel more round. After China became the world's factory, foreign proc...essing equipment have been in China, of course, is that they use the technology.
In fact, whether imported or domestically produced equipment at the same price will not differ too much, do not own a lot of domestic R & D capabilities, without its own core technology manufacturers, buy a different quality of different brands of vacuum equipment parts are assembled into a finished (vacuum equipment contains components), the higher the price the better part quality, cheap quality parts using vacuum equipment is relatively poor, since the parts can do the same, technology, domestic equipment how there might be a difference than abroad? Some have their own R & D capabilities of equipment manufacturers, their equipment will be developed where there are some advantages. Of course, it is undeniable that the country's own technology to be worse than in some countries, if a vacuum device all with the domestic manufacturers developed their own brand products, in terms of quality and performance, but perhaps more than Germany, Japan's machine, but it has price advantage.
Now domestic vacuum coating machine is mainly imported from Germany, Japan, Korea equipment.
Germany is relatively expensive vacuum equipment, vacuum equipment with light control Japan's slightly more expensive, with only external crystal controlled in two hundred or so, with light control, crystal controlled, the ion source of about five million. Price Korea vacuum devices with light control, crystal controlled, the ion source of nearly two-thirds of Japan around.
In fact, many foreign brands of equipment are domestic procurement of hardware, domestic brands are foreign buyers a lot of hardware equipment, vacuum equipment, the best choice is based on the production of products to select the machine, such as the election computers in general, do not buy brand machine, assembly cost maybe higher.

The basic concept of PVD coating and its characteristics

The basic concept of PVD coating and its characteristics
The abbreviation of PVD is English 'Physical Vapor Deposition' form, Physical Vapor Deposition. We are now generally the vacuum evaporation, sputtering deposition, ion plating, etc. Are called physical vapor deposition.
Relatively mature PVD methods mainly include many arc and magnetron sputtering plating in two ways. Many arc plating equipment simple structure, easy to operate. The ion source by electric welding machine power supply can work, its process is similar to electric welding arc, specifically, to a certain process under pressure, arc needle contact with evaporation ion source is short, disconnect, make the gas discharge. Due to the cause of arc coating is mainly by means of moving arc spot, the evaporation source for formation of molten pool on the surface, make the metal evaporated, the film layer is deposited on the substrate, compared with the magnetron sputtering, it not only has the target material utilization rate is high, high ionization rate, more metal ions film the advantages of strong adhesion. In addition, many arc plating coating color is relatively stable, especially when doing the TiN coating, each batch are easy to get the same stability of golden, the magnetron sputtering method. Arc plating deficiency is more, in traditional DC power supply under the condition of low temperature coating, when the coating thickness at 0.3 microns, deposition rate and reflectivity, film become very difficult. And the thin film surface became meng. Arc plating another deficiency is more, because the metal is molten after evaporation, so deposited particles is bigger, low density, poor wear resistance than magnetron sputtering film.
Visible, more arc deposition and magnetron sputtering coating each have advantages and disadvantages, as far as possible in order to play their respective advantages, realize the complementary, will more arc technology and magnetic control technology becomes one of the coating machine arises at the historic moment. Appeared more arc plating on craft firstly, and then using the method of magnetron sputtering coating thickening, final reuse arc plating to achieve more stable new method for the surface of the coating color.

Principle of vacuum coating equipment

      Principle of vacuum coating equipment
Electronic under the action of electric field, accelerate the process of flying to the substrate with argon atom collision, ionization out large amounts of argon ions and electrons, electronic fly to the substrate. Accelerated in the electric field under the influence of argon ion bombardment of target materials, sputtering out a large number of target material atoms, the target of neutral atoms (or molecules) is deposited on the substrate into film. Secondary electron in accelerating the process of flying to the substrate by magnetic lorentz magnetic force, the influence of bound in * plasma on the surface of the target area, the area of plasma density is high, secondary electron under the action of magnetic field around the target surface as a circular motion, the electron motion path is very long, constantly in the process of movement and argon atom collision ionization out large amounts of argon ion bombardment of target, electronic energy reduce gradually, after many collision cast off the yoke of the magnetic field lines, away from the target material, the final deposition on the substrate.
Magnetron sputtering is with magnetic field and to extend the electronic motion path, change the movement direction of the electron, improve the working gas ionization rate and the effective utilization of the energy of an electron.
Electronic home is more than substrate, vacuum chamber wall and target source anode and electronic home. But usually substrate with the vacuum chamber and the anode in the same electric potential. The interaction of the magnetic field and electric field (E X B shift) to assume a single electron trajectory three-dimensional spiral, rather than merely to circular motion on the target surface. As for the target surface sputtering outline of the circle type, that is the target source magnetic field lines in circular shape shape. The lines of magnetic force distribution in a different direction to film has a lot to do.
Work under E X B shift mechanism not only of magnetron sputtering, arc plating target source, ion source, plasma source in time under the principle of work. The difference is the electric field direction and size of the voltage and current.

Domestic and vacuum equipment

Domestic and vacuum equipment
Some say the most durable German vacuum equipment, vacuum equipment, the most beautiful of Japan, South Korea, the most tangled vacuum equipment, vacuum equipment China's most ugly. In fact, many people do not find the same configuration for domestic and imported products at the same price or contrast ratio, the heart inside the moon always kind of feel more round. After China became the world's factory, foreign processing equipment have been in China, of course, is that they use the technology.
In fact, whether imported or domestically produced equipment at the same price will not differ too much, do not own a lot of domestic R & D capabilities, without its own core technology manufacturers, buy a different quality of different brands of vacuum equipment parts are assembled into a finished (vacuum equipment contains components), the higher the price the better part quality, cheap quality parts using vacuum equipment is relatively poor, since the parts can do the same, technology, domestic equipment how there might be a difference than abroad? Some have their own R & D capabilities of equipment manufacturers, their equipment will be developed where there are some advantages. Of course, it is undeniable that the country's own technology to be worse than in some countries, if a vacuum device all with the domestic manufacturers developed their own brand products, in terms of quality and performance, but perhaps more than Germany, Japan's machine, but it has price advantage.
Now domestic vacuum coating machine is mainly imported from Germany, Japan, Korea equipment.
Germany is relatively expensive vacuum equipment, vacuum equipment with light control Japan's slightly more expensive, with only external crystal controlled in two hundred or so, with light control, crystal controlled, the ion source of about five million. Price Korea vacuum devices with light control, crystal controlled, the ion source of nearly two-thirds of Japan around.
In fact, many foreign brands of equipment are domestic procurement of hardware, domestic brands are foreign buyers a lot of hardware equipment, vacuum equipment, the best choice is based on the production of products to select the machine, such as the election computers in general, do not buy brand machine, assembly cost maybe higher.

Film, thin film coating on the vacuum introduction

                            Film, thin film coating on the vacuum introduction
Film: the film can be considered a two-dimensional material. In the strict academic sense, that only aggregate thickness is less than the thickness of the material characteristics of a real film, otherwise it is generally thin material. Characterized thickness: is the nature of the use of certain basic materials phenomenon will occur abnormal changes in the case of thin material thickness aggregation determined, i.e., when selected for a physical or mechanical properties different from the reference beginning to show it typically has a thickness characteristics when, is characterized in substance to the film thickness.
The main properties of the film:
Thickness: The more uniform the better, should generally be controlled within a range, such as 5, which is about the size of the workpiece coating system
Film surface morphology: transmission electron microscope by scanning electron microscopy (SEM) (TEM) analysis showed the like particle state, the availability of dense film surface, defect status, the annealing treatment on the membrane surface and other information.
Membrane organization features: X-ray diffraction analysis of the composition of the film, and other information available to the purity of the film. Film stress: the smaller the better films of internal stress, the internal pressure of the annealing process can maximize the release of the film.
Characteristics of the film and the substrate contact: mainly refers to the adhesion between the film and the substrate, of course, the stronger the better adhesion, the film appears to avoid missing the open and so on.
Dense membrane: mainly refers to film hardness and abrasion resistance, to avoid the open circuit external scratches caused.
Chemistry membrane, thermal stability: the requirements for the metal film layer of the metal film layer prepared resistivity as low as possible, close to the bulk resistivity.
Film analysis commonly used methods:
Scanning electron microscopy SEM analyzes 10nm resolution is generally more than surface information, sample preparation simple.
Transmission electron microscopy TEM analyzes structural information, resolution of less than 1 atom, sample preparation difficult.
XRD analysis of the structure is the information, but can not analyze micro-structure information for the film, XRD given direction, SEM choose a good area, TEM-depth analysis, which is a combination of boxing.
