Patent ID: 7651888

Claim:
A fixture for packaging micro-electro-mechanical-system (MEMS) devices comprising: a base having a surface and defining a plurality of units, which each includes a notch located in the surface; a first material layer disposed on the surface of the base and the notches; an insulating layer disposed on a part of the first material layer and exposing the other part of the first material layer located on the notches; and a second material layer disposed on the other part of the first material layer located on the notches, the second material layer being formed with a plurality of caps, whereby the caps are physically connected to the MEMS devices, and the MEMS devices are corresponding to the units of the base, wherein there is a first connecting force between the first and second material layers, there is a second connecting force between the caps and the MEMS devices, and the second connecting force is greater than the first connecting force.
