摘要:
A method of fabricating an encapsulated micro electro-mechanical system (MEMS) and making of same that includes forming a dielectric layer, patterning an upper surface of the dielectric layer to form a trench, forming a release material within the trench, patterning an upper surface of the release material to form another trench, forming a first encapsulating layer that includes sidewalls within the another trench, forming a core layer within the first encapsulating layer, and forming a second encapsulating layer above the core layer, where the second encapsulating layer is connected to the sidewalls of the first encapsulating layer. Alternatively, the method includes forming a multilayer MEMS structure by photomasking processes to form a first metal layer, a second layer including a dielectric layer and a second metal layer, and a third metal layer. The core layer and the encapsulating layers are made of materials with complementary electrical, mechanical and/or magnetic properties.
