Q:What are the raw materials of silicon wafers
Silicon transistorSemiconductor materials can be divided into silicon and germanium transistors. According to the polarity of the transistor can be divided into germanium NPN transistor, germanium PNP transistor, silicon NPN transistor and silicon PNP transistor.
Q:Wafer size6 inches and 8 inches only refers to the diameter of monocrystalline silicon?
Refers to the diagonal length of the silicon waferBut you asked the wrong question, the wafer is divided into monocrystalline silicon and polycrystalline silicon wafer, you say is a square of silicon polysilicon film of silicon wafer, you ask in the four corner is a circular arc shape, so you should also count the length of the diagonal right. If not to shape the polysilicon film solution you can search the Internet search look.
Q:How to do on the silicon wafer
The general use of ultrasonic and pre cleaning (pickling) can be solved
Q:How to make monocrystalline silicon solar cells
Surface fleeceThe preparation of single crystal silicon wafer is the use of anisotropic etching of silicon on the surface of the silicon per square centimeter to form several million square pyramidal structure, namely, the Pyramid structure. Due to the multiple reflection and refraction of incident light on the surface, the absorption of light is increased, and the short circuit current and conversion efficiency are improved. Anisotropic etching of silicon in alkaline solution liquid is usually hot, available alkali sodium hydroxide, potassium hydroxide, lithium hydroxide and ethylenediamine etc.. Most of them were prepared by using dilute sodium hydroxide solution with a concentration of about 1%, and the corrosion temperature was 70-85. In order to obtain a uniform texture, but also in the solution add alcohols such as ethanol and isopropanol as complexing agent to accelerate the corrosion of silicon. In the preparation of velvet, the silicon chip must be first surface corrosion, alkaline or acidic etching solution to about 20 ~ 25 m, corrosion in the face, the general chemical cleaning. After surface preparation of silicon wafers are not suitable for long-term storage in the water, in order to prevent contamination, should be spread as soon as possible.
Q:After cutting a few chips, mortar density is getting lower and lower
Iron powder and silica fume more and more, the density should be more and more big, unless it is your water content is higher and higher
Q:What are the difficulties of silicon wafer cutting?
1, the impurity line caused by impurities in polycrystalline silicon ingot, slicing process can not completely remove the lead line on a silicon wafer.2, scratch line caused by mortar in large SIC particles or caking mortar. In the process of cutting, SIC particles stuck in between steel wire and silicon can not overflow, cause.Forms: including the whole line and half line marks, concave line, shiny, more narrow than the other.
Q:Is the thickness of solar cell silicon wafer certain? Specifically how much
In fact, the thinner the better, because it is really used to do only 20um PN junction is enough
Q:I would like to ask what the purpose of the use of semiconductor silicon wafers, doped with boron ah?
High purity silicon wafers for use in electronics and solar energy are required to be doped with boron to manufacture the P end of the P - N junction, in which P (P) - N (As) -, Ga (B) - gallium (III) indium (III) - silicon.
Q:What is the role of silicon wafer annealing furnace, what specific requirements
I want to be the temperature to more than 1 thousand degrees, and then clean the furnace
Q:How to deal with silicon wafer annealing
Silicon wafer annealing process, is a part of the process. According to a certain procedure, the process of heating and cooling..;
