Q:What does TTV mean in silicon wafer production?
Thickness variation of TTV: wafer. Generally speaking, the thickness of silicon wafer has no effect on the quality of silicon wafer. The only thing that really works in a silicon chip is a thin layer of silicon, and the rest is supported
Q:Why should the wafer cut side, cut out edge Jiaosha
In fact, early silicon is not cutting edge, but with the development of microelectronics industry began the following reasons: cutting edge, W2) i: J n$W% L* M1 s `&;1, n can do a plurality of microelectronic devices on the wafer, cut down, and there is a crystal to crystal growth requirements, cutting along a direction for cutting chaos crack, cleavage is the professional said. The cutting edge tells you the direction of cleavage.2, N type and P type silicon wafer, a standard trimming is also inform you that it is n type or P type electrical characteristics, electrical characteristics, u$J2 z/ h 9 - O3, microelectronics production has been automated, such as lithography exposure if there is no cutting edge positioning, then the mask plate and the chip will be a difference of 180 degrees or a certain location, production efficiency will be very low...,4, the use of a lot of silicon, in addition to n/p also have crystal direction, for example, do MEMS requires corrosion anisotropy will be used <110> crystal direction, and MOS products in order to reduce the influence of the surface state requirements with <100> crystal...
Q:What is the role of the semiconductor wafer
The main role of the glue is coated with photoresist coated flat, the use of high-speed rotation of the centrifugal force
Q:How do we use the scanning electron microscope
After wiping with cotton wool, wash ear ball can be dried.Some of the words can be placed in alcohol solution ultrasonic cleaning, the effect is almost.
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:What is the thickness of the semiconductor wafer used today?
We do DIP package, 4 inch wafer to be thin to 0.300mm; 6 inch wafer to be reduced to about 0.320mm, error 0.020mm.
Q:Wafer size6 inches and 8 inches only refers to the diameter of monocrystalline silicon?
Another 6 inches =152.4mm, 8 inches =203.2mmThe following is a general standard for monocrystalline silicon wafers:6 "x09153mm is more than phi = 158 mm6.2 "x09159 mm = phi = 164 mm6.5 "x09168 mm = phi = 173 mm8 "x09203 mm = phi = 208 mm
Q:What is a silicon wafer
Silicon is an important material in the IC fabrication, through photolithography and ion implantation on the silicon wafer and other means, can be made into various semiconductor devices made of silicon chip. With amazing computational capabilities. The development of science and technology promotes the development of semiconductor. Development of automation and computer technology, this makes the silicon chip (integrated circuit) high technology product cost has been reduced to a very low degree. This makes the silicon wafer has been widely used in aerospace, industry, agriculture and national defense, and even crept into every family.
Q:The problem of integrated circuit fabrication is how to realize the functions of capacitors, resistors and transistors on a single chip
For you to say the popular point, just like a piece of cake dug out of different shapes and different holes complex to the level, to know that silicon is a semiconductor
Q:Why integrated circuits are rectangular and the silicon chips are round
The disk that you see is a wafer. This disk is not only the production of a chip, but N multiple chips are produced in this disk.
