Abstract:
1. A method of making a microelectromechanical systems (MEMS) device package comprising: forming a MEMS device on a front side of a first substrate; removing a portion of said substrate partially surrounding an active region of said MEMS device to form a cantilevered substrate platform at which said active region resides; attaching a back side of said first substrate to a second substrate, said attaching operation including forming a clearance space between said cantilevered substrate platform and said second substrate so that said cantilevered substrate platform is suspended above said second substrate; positioning a plug member overlying said cantilevered substrate platform; following said attaching and positioning operations, applying a molding compound to encapsulate said MEMS device; and following said applying operation, removing said plug member and coupling a cap to said first substrate overlying said cantilevered substrate platform, said cap including an interior volume to provide a gap between said cap and said active region of said MEMS device.
