MEMS is Micro Electro Mechanical System meaning technology
for micro semiconductor processing.
This technology is to integrate electric and mechanical
parts into micro small size one, and MEMS means to fabricate
a system with new function by combining mechanical structure
and electric structure of micro scale together.

: Seju’s
Gas sensor is a product in which MEMS technology was used
for the 1st time in Korea. Our Gas sensor is the 1st commercialized
MEMS gas sensor in the world.
: As Seju’s Gas sensor used MEMS technology
instead of sensor method which uses previous general processing
technology, we realized low price and the best quality
for gas sensor product. : Seju’s
Gas sensor is in the process of application for patents
in many countries in the world.
