Abstract:
A MEMS device having a channel configured to avoid particle contamination is disclosed. The MEMS device includes a MEMS substrate and a base substrate. The MEMS substrate includes a MEMS device area, a seal ring and a channel. The seal ring provides for dividing the MEMS device area into a plurality of cavities, wherein at least one of the plurality of cavities includes one or more vent holes. The channel is configured between the one or more vent holes and the MEMS device area. Preferably, the channel is configured to minimize particles entering the MEMS device area directly. The base substrate is coupled to the MEMS device substrate.
