Q:The purpose and means of chemical etching of silicon wafers?
After slicing and grinding, the surface of silicon wafer has a layer of damage and pollution due to processing stress
Q:After the completion of the silicon chip will appear in the shadow of the white spots or what is the situation? How to solve
Check the cleaning agent is uniform, cleaning time is appropriate
Q:How to make a resistor on a silicon chip (integrated circuit)
The site is general one-sided, to consult the detailed understanding of literature, over the wall out to find it, say one thirty,
Q:The relationship between the weight and the power of solar wafers!
156*156,8 inch polysilicon chip Accounting: efficiency of 16%, the thickness of the silicon chip is 180, corresponding to the amount of polysilicon per watt on the map is 7G.
Q:Silicon rod / wafer processing production
(4): end shoulder growth after a long thin neck, to reduce the temperature and casting speed, the crystal diameter gradually increased to the desired size. (5) the diameter growth: after a long neck and shoulder end, by continuously adjusting casting speed and temperature, the crystal diameter maintained at between 2mm positive and negative, the diameter of fixed part is called the diameter part. Monocrystalline silicon wafer from the equal diameter part. (6) tail growth: if the rod is separated from the liquid surface, the effect force will cause the dislocation and slip line of the crystal rod. So in order to avoid the occurrence of this problem, the diameter of the crystal rod must be gradually reduced until it is a sharp point and separated from the liquid surface. This process is called tail growth. After a long period of time, the crystal rod is taken out of the furnace chamber for cooling for a period of time to complete a growth cycle.
Q:The microprocessor integrates the computer with what is on a small silicon chip
Arithmetic unit, a computer that performs arithmetic and logic operations. The basic operation of the device, including addition, subtraction, multiplication, division of the four operations, and, or, not, XOR logic operations, as well as the shift, comparison and transfer operations, also known as arithmetic logic unit (ALU).
Q:Why is it not easy to use high resistance on the silicon chip integrated circuit
For boron diffusion resistance, its resistivity is determined by the use of a greater length / width ratio, which is subject to the limitations of process and wafer area
Q:How to detect the surface finish of photovoltaic silicon wafers, what equipment?
Physical examination of the surface roughness on the line, whether it can be cleaned with chemical or optical
Q:Why not use N type silicon crystal silicon battery
The first price is high, the N substrate cell conversion efficiency is high, the price is not cheap, good efficiency of P type silicon do not end; second, N doped phosphorus, phosphorus and silicon phase solubility, pull rod phosphorus uneven distribution of P type silicon doped boron, boron and silicon segregation coefficient of equivalent uniform dispersion is easy to control.
Q:Is solar silicon wafer often harmful to the body?
Thousands of years of evolution of organisms around the common substances are toxic to stimulate immune function.
