INTRODUCTION TO C/C COMPOSITE
Monocrystalline silicon wafer is a good semiconductor material, which is mainly used in the manufacture of semiconductor devices, solar cells and so on. The processing size of the monocrystal silicon wafer produced by Yujing can be from 166mm to 230mm, and the thickness can meet all needs of
the market.
Peculiarity
-
01
The equipment is independently developed and manufactured.
-
02
Large variable axis ensures a wide range of wafer processing sizes and issuitable for wafer sizes from 166 to 230 as well as 210 half wafers.
-
03
Our inspection standard to processed silicon wafer is more strict. The test items such as TTV and thread trace value are lower than the industry standard value 2μm.
-
04
The distribution range of wafer thickness is within 1μm.
