Abstract
A wafer-level packaged integrated circuit includes a semiconductor substrate including a first silicon layer. A micro-electromechanical system (MEMS) device is integrated into the first silicon layer. A thin-film deposited sealing member is deposited over the first silicon layer and is configured to seal a cavity in the first silicon layer. At least one additional layer is formed over the sealing member. At least one under bump metallization (UBM) is formed over the at least one additional layer.
