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: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:Wafer cutting will appear thick sheet, I would like to ask what the reasons are
Solving measures:A. guide slot check slot is uniform, and to compensate for the loss according to the situation of the slot wheel.When the A. is set to zero, the position of the guide line is controlled.B. standard viscose operation. When the surface of the silicon block is bonded with the guide bar, the utility model can be used to check whether the guide strip is bent, and whether the glue is evenly applied, so that there is no gap between the guide strip and the silicon block after the bonding guide strip is arranged.In the process of using the C. guide wheel, the utility model is used to detect the guide groove of the guide wheel on a regular basis, and the depth and the angle of the guide groove are observed.
Q:The higher the resistivity of silicon wafers, the better?!!
Weak questions: why single crystal resistivity in about 1 would be better?
Q:What is the harm of silicon chip into the fingers?
The silicon rod into silicon wafer after printed, someone with bare hands touched the wafer, because the chemical composition of the finger is very complex, in the cleaning process is not removed, causing subsequent corrosion is not uniform, the more to the more obvious after section
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:What is the thickness of the semiconductor wafer used today?
For integrated circuits: generally 4 inch wafer thickness of 0.520mm, the thickness of the 6 inch wafer
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:Light doped and heavily doped silicon wafers
Otherwise, the light is mixed, N++/P++ said heavy doping, no plus is light, thank you
Q:What are the raw materials of silicon wafers
Polysilicon material:1 solar polysilicon: 6N, P2 head tails: P3 broken semiconductor wafer: P type, arc type debrisPrice: $200 / kg
