ABSTRACT:
An integrated MEMS package and associated packaging method are provided. The method includes: forming an electrical circuit, electrically connected to the first substrate; integrating a MEMS device on a first substrate region, electrically connected to the first substrate; providing a second substrate overlying the first substrate; and, forming a wall along the first region boundaries, between the first and second substrate. In one aspect, the electrical circuit is formed using thin-film processes; and, wherein integrating the MEMS device on the first substrate region includes forming the MEMS using thin-film processes, simultaneous with the formation of the electrical device. Alternately, the MEMS device is formed in a separate process, attached to the first substrate, and electrical interconnections are formed to the first substrate using thin-film processes.
