Homray Material Technology offers silicon wafers,3 inch to 12inch
Si wafer in different quality grades for researcher grade silicon
wafer, dummy grade wafer and production Si wafer. As a professional
manufactur company ,we are devoted to continuously improve the
quality of currently substates and develop large size substrates.
Test Grade Wafers are high quality wafers which have less
comprehensive specifications than a prime grade wafer.
These wafers monitor the performance and conditions of a particular
semiconductor processing step. The Test Grade Wafer provides a more
economical solution for isolated testing.
Dummy wafers are wafers mainly used for experiment and test and
being different from general wafers for product.Dummy wafers are
often used in a production line to improve safety in the beginning
of production process and are used for delivery check and
evaluation of process.
