摘要
Disclosed is a MEMS device having lower, upper and release chambers with a similar pressure and/or a similar gaseous chemistry. The MEMS device includes a top MEMS plate and a bottom MEMS plate. The MEMS device also includes a lower chamber between the bottom MEMS plate and the top MEMS plate, and an upper chamber between the top MEMS plate and a first sealing layer. The MEMS device further includes a release chamber between the top MEMS plate and a second sealing layer, the release chamber allowing gaseous content of the upper and/or the lower chambers to be released. Also disclosed is a double release method for releasing gaseous content of the upper and/or the lower chambers.
