Abstract:
A method for packaging a microelectromechanical system (MEMS) device comprising:using a partially-cured adhesive to attach first and second release sheets on first and second sides of a MEMS package flexible layer; ablating the MEMS package flexible layer and at least one of the first and second release sheets to provide a cavity extending completely through the MEMS package flexible layer and the at least one of the first and second release sheets, removing the first and second release sheets; attaching a cover over to the MEMS package flexible layer such that the covet overlies the cavity, wherein attaching the cover occurs prior to removing the second release sheet; and attaching the MEMS device to the MEMS package flexible layer with a MEMS structure of the MEMS device being positioned within the cavity.
