SEMICONDUCTOR DEVICE HAVING A METAL PATTERN AND A PIEZOELECTRIC PATTERN

摘要

The present invention relates to a semiconductor device having a metal pattern and a piezoelectric pattern. More specifically a semiconductor device which includes: a passivation layer for defining a metal pattern on a first surface of a substrate; a minor insulation layer on a second surface of the substrate; and a piezoelectric pattern formed between the metal pattern and the passivation pattern, on the first surface of the substrate, is provided.
