PLANE (1-102) SAPPHIRE WAFERS

R plane(1-102) sapphire wafers are preferred for the hetero-epitaxial
deposition of silicon used in microelectronic IC applications. R plane is the
non-polar plane of sapphire. So the different positions of R-plane in sapphire
devices, the mechanical, thermal, electrical and optical properties of sapphire
devices will vary greatly, which will also affect the subsequent processing
performance, processing efficiency and processing yield of sapphire devices.

In order to make the crystal structure of sapphire ingot and subsequent
sapphire products consistent, the more common method is to process an A-
direction surface on the sapphire ingot as the flat orientation of sapphire
wafer (subsequent sapphire products), so that the R-direction position of
sapphire ingot and the wafer is consistent.
