Abstract: A method and structure for a PLCSP (Package Level Chip Scale Package) MEMS package. The method includes providing a MEMS chip having a CMOS substrate and a MEMS cap housing at least a MEMS device disposed upon the CMOS substrate. The MEMS chip is flipped and oriented on a packaging substrate such that the MEMS cap is disposed above a thinner region of the packaging substrate and the CMOS substrate is bonding to the packaging substrate at a thicker region, wherein bonding regions on each of the substrates are coupled. The device is sawed to form a package-level chip scale MEMS package.
