200 mm MEMS Line

Teledyne DALSA's 200 mm MEMS line has been installed to provide capacity for higher volume production, and to support wafer level bonding of MEMS to 200 mm CMOS wafers. There is a high degree of commonality between our 150 mm and 200 mm MEMS line and most applications which run on 150 mm can be transferred to 200 mm if required.
