Packaged MEMS device assembly
First Claim
1. A packaged micro-electromechanical systems (MEMS) device assembly comprising:
- a MEMS device;
a substrate within which the MEMS device is disposed;
a lid disposed over the substrate; and
,one or more of;
one or more first cavities within the lid having a predetermined volume satisfying packaging specifications for the packaged MEMS device assembly;
one or more second cavities within the lid and one or more corresponding overflow areas within the lid, each second cavity containing a material and each corresponding overflow area adapted to catch overflow of the material, where each second cavity is overlapped by a corresponding overflow area having a width greater than a width of the second cavity and a depth shallower than a depth of the second cavity; and
,one or more third cavities within the lid and one or more channels within at least the substrate to fluidically connect the MEMS device to the third cavities, where the channels are narrower than the third cavities.

Abstract
A packaged micro-electromechanical systems (MEMS) device assembly includes a MEMS device, a substrate within which the MEMS device is disposed, and a lid disposed over the substrate. The assembly may include one or more first cavities within the lid having a predetermined volume satisfying packaging specifications for the packaged MEMS device assembly. The assembly may include one or more second cavities within the lid and one or more corresponding overflow areas within the lid, where each second cavity contains a material and each corresponding overflow area is adapted to catch overflow of the material. The assembly may include one or more third cavities within the lid and one or more channels within one of the substrate and the lid to fluidically connect the MEMS device to the third cavities.
