Abstract:
Disclosed are an MEMS type semiconductor gas sensor using a microheater having many holes and a method for manufacturing the same. The MEMS type semiconductor gas sensor includes: a substrate of which a central region is etched with a predetermined thickness; a second membrane formed at an upper portion of the central region of the substrate and having many holes; a heat emitting resistor formed on the second membrane and having many holes; a first membrane formed on the second membrane including the heat emitting resistor and having many holes; a sensing electrode formed on the first membrane and having many holes; and a sensing material formed on the sensing electrode.
