Abstract

A method for manufacturing integrated circuit device lids includes creating a lid cavity on the surface of a lid wafer, forming a sealing surface on the lid wafer that surrounds the lid cavity, and forming a trench on the lid wafer between the lid cavity and the sealing surface. The resulting structure uptakes excess sealing surface material and prevents such material from entering the lid cavity.
