Claim Text:
1. An integrated circuit package comprising: a first semiconductor substrate having a top surface and a bottom surface with a microelectromechanical system (MEMS) structure and at least one a contact pad formed on said top surface, said at least one contact pad being formed over a non-recessed portion of said top surface; a second semiconductor substrate having a top surface and a bottom surface and having a cavity with an opening in said bottom surface, wherein said bottom surface of said second semiconductor substrate is attached to said top surface of said first semiconductor substrate, and wherein said MEMS structure is positioned inside said cavity and said at least one contact pad is positioned outside said cavity; and a leadframe having a die attachment pad and at least one lead, wherein said first semiconductor substrate is mounted on said die attachment pad and wherein said at least one contact pad is attached by at least one bond wire to said at least one lead.
