MICRO-ELECTRO-MECHANICAL SYSTEM (MEMS) STRUCTURES AND DESIGN STRUCTURES

摘要

Micro-Electro-Mechanical System (MEMS) structures, methods of manufacture and design structures are disclosed. The method includes layering metal and insulator materials on a sacrificial material formed on a substrate. The method further includes masking the layered metal and insulator materials. The method further includes forming an opening in the masking which overlaps with the sacrificial material. The method further includes etching the layered metal and insulator materials in a single etching process to form the beam structure, such that edges of the layered metal and insulator material are aligned. The method further includes forming a cavity about the beam structure through a venting.
