Sapphire material is now widely used in optical and semiconductor industry, with hardness second only to diamond and chemical and scratch resistance and thermal stability ,it is superior to other materials such as quartz.
Sapphire carrier are used to hold and transport thin film processing of silicon,GaAs other semiconductor wafers and flexible substrates.
All thin substrate carriers are ultra flat and can be supplied with or without custom perforated holes,other option of porous ceramic is also our expertise.
Current sizes are available typically from 2" to 12" dia with flatness and parallelism of 0.002-0.005mm, large size till 20 inches is also successfully prototyped.
