Patent ID: 8188799

Claim:
A microelectromechanical system (MEMS) comprising: a first structure, the first structure including a first substrate having first and second surfaces that face each other, the first substrate including a via etching hole pattern penetrating the first surface and the second surface and a first non-via etching hole pattern penetrating the first surface; and a second substrate bonded to the first substrate, the second substrate having third and fourth surfaces that face each other, the second substrate including a second non-via etching hole pattern penetrating the third surface in a position corresponding to the via etching hole pattern of the first substrate, wherein the MEMS further comprises metal thin films formed on the first surface, the second surface, the third surface, and etched surfaces of the via etching hole pattern of the first structure, the first non-via etching hole pattern of the first structure and the second non-via etching hole pattern of the first structure.
