PZT

Piezoelectric Thin Film Sputtering Service

PZT has high piezoelectric constant and its thin film can be patterned finely making it ideal for MEMS sensors.

High Reliability - mass production experience (1,000,000 per year) brings stable quality.
Quick Delivery - Please contact us to discuss your required schedule.
Small Volume Welcomed - Single wafer prototyping available.
Reasonable Cost - Please contact us for a quotation.
