Q:8 inch monocrystalline silicon area?
Generally refers to the round wafer, 8 inch refers to the diameter of 8 inches, "=2.54cm", the area of the circle you will ask for 1.
Q:Development trend of monocrystalline silicon wafer
The development of science and technology is driving the development of semiconductors. With the development of automation and computer technology, the cost of this kind of high technology product of silicon chip (integrated circuit) has been reduced to a very low level. The price of a mini computer is only a few hundred yuan. This paved the way for the computer to enter thousands of households. Make our life more and more modern.Of course, the changes in the chip to the family is far more than that, with the increase in the number of electronic households, a new production lifestyle - "home industry" and "home office" is being produced. In the future, sitting at home operating machines, command production and management companies and factories, will become a reality The day is not too distant when.
Q:After the velvet or the original silicon
After the wafer is not cleaned clean, you should be monocrystalline wafers
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:I grew Ag particles on a silicon wafer, about a few hundred nanometers in size
Alcohol is usually placed inside, with ultrasonic cleaning instrument scattered about, the purpose is to make the particles do not reunite together.
Q:What are some of the silicon wafer factory
2 raw materials for deputy director, assistant director of the workshop material sorting and packaging materials packaging materials sorting operator monitor corrosion monitor cleaning cleaning raw materials warehousing operator member subtotal deputy director of the 3 crystal sandblasting operator workshop director assistant assistant statistician crystal crystal pulling monitor operator cut cut monitor operator subtotal
Q:Why can silicon chips store information? Even if it is a miniature circuit, unplug the power will be no electricity
The principle of the board as you say, the power can be changed according to the requirements of the crystal in the electronic case, the power will not stop after the move, but also as the pawn as the preservation of information,
Q:What can be used to adjust its viscosity
If you are slicing, don't adjust it yourself. The final formulation of the mortar with the proportion of mixing time, there is a relationship. The proportion of the appropriate density viscosity enough to find manufacturers
Q:Consult the difference between silicon and battery
And the battery slice is cut the silicon wafer cleaning, making, P/N knot, printing and so on after the results of the process, directly cut the silicon chip can not be used for power generation.
Q:What is the use of silicon?
The domestic semiconductor leader GRINM (600206) general manager Zhou Qigang told reporters that the original price is less than $30 per kilogram of raw materials of polysilicon, now prices rose to about $110 per kilogram, affected by this, GRINM 2005 production costs increased by 30 million yuan.Zhou Qigang believes that the culprit is the price of polysilicon solar cells. Because of the global crude oil prices, rising demand for new energy in Europe and the United States, these countries have taken measures to encourage the development of solar energy, the solar energy industry is booming, leading to the surge in demand for polysilicon.
