- Q:What is the harm of silicon chip into the fingers?
- It is also easy to cause other damage, if a small piece of debris along with the flow of blood to the heart, it is very dangerous
- Q:How many watts can a piece of silicon produce
- The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Because silicon is one of the most abundant elements in the earth, the solar battery that destined to enter the mass market (mass market) products, reserves of advantage is to become one of the reasons the main photovoltaic silicon materials.
- Q:There is a micro structure on the side of the silicon wafer
- It is a milestone in the progress of science and technology that 160 thousand transistors have been integrated on a large grain of silicon.
- Q:How much is the thickness of the silicon wafer
- Around 0.670mm. Wafer must be thinned, otherwise the loss of dicing knife
- Q:What is a good solar wafer testing equipment?
- QCROBOT has been the solar energy as the focus of their products to promote the industry, and has a variety of measurement and control products, for the field of solar energy has launched a variety of measurement and control programs. For example, photovoltaic semiconductor production process control, solar power plant power monitoring system, as well as photovoltaic solar cell volt ampere characteristics test. QCROBOT machine vision system can be used to monitor the shape and size of silicon particles at high temperature. Machine vision can also be used to monitor the quality defects, size measurement, and so on of crystal rods, wafers, panels and components. At present, the QCROBOT vision system and the measurement and control software and hardware platform have been successfully applied to the production and installation process of the solar panel.
- Q:What is the meaning of the wafer (100), the crystal orientation index or the crystal plane index
- Said the origin and the point of x = 1, y = 1, the linear Z on the =1 atoms, if the crystal is body centered cubic lattice, the crystal orientation through the cube on the diagonal of the atom.
- Q:How to avoid or reduce the fragmentation of thin silicon wafers without wax polishing?
- You can use the U.S. ZeroMicron wax free polishing template to solve the problem of non wax polishing fragments
- Q:I would like to ask the solar cell (silicon) production process is the principle of how
- Three, diffusion systemSolar cells require a large area of PN junction to achieve the conversion of light energy to electrical energy, while the diffusion furnace is a special equipment for manufacturing solar cell PN junction. Tube type diffusion furnace is mainly composed of quartz boat download four parts part, gas chamber, a furnace body part and a holder part etc.. Generally, the liquid source of three phosphorus oxychloride is used as the diffusion source. The P type silicon wafer is placed in a quartz tube of a tube type diffusion furnace, and three nitrogen oxychloride is used in the quartz vessel at the temperature of 850---900 degrees Celsius, and the phosphorus atom is obtained through the reaction of the phosphorus oxychloride and the silicon wafer through the reaction of the phosphorus and the phosphorus. After a certain time, the phosphorus atom from the surrounding surface layer into a silicon wafer, and wafer to internal diffusion through the void between the silicon atoms, forming a N type semiconductor and P type semiconductor interface, namely PN junction. The PN junction made by this method has good uniformity, the uniformity of box resistance is less than ten percent, and the lifetime of less than 10ms. The manufacture of PN junction is the most basic and most important process in the production of solar cells. Because it is the formation of PN junction, so that the electrons and holes in the flow is no longer back to the original place, so that the formation of the current, using the wire will lead to the current, dc.
- Q:What are the aspects of silicon wafer testing?
- Test wafer sizeThe damage degree of monocrystalline silicon wafer was measured and classified:Damage less than 30mm, can be cut into 6 inches Wafer;Broken into two pieces, can not be used;No damage;Wafer size 156*156mm;Detection speed requirements: 1.5 seconds / piece;Action process: the movement of the wafer to the detection position, the camera quickly take pictures, and then processed in the process of equipment;Wafer movement speed: about 150mm/s;
- Q:How to make the photoresist and silicon substrate adhesion better
- A thin layer of HMDS (hexamethyldisilazane) can be applied on the bottom layer of the silicon wafer, and then coated with PR, the main function of the solvent is to make the surface structure of the SIO2 of the silicon chip to be changed from hydrophilicity to hydrophobicity
