Abstract

A Micro-Electro-Mechanical System (MEMS). The MEMS includes a lower chamber with a wiring layer and an upper chamber which is connected to the lower chamber. A MEMS beam is suspended between the upper chamber and the lower chamber. A lid structure encloses the upper chamber, which is devoid of structures that interfere with a MEMS beam. The lid structure has a surface that is conformal to a sacrificial material vented from the upper chamber.
