Abstract:
A method of fabricating a MEMS device includes performing an atomic layer deposition (ALD) process to deposit a barrier layer such as Aluminum Oxide (AI2O3) having a thickness on a sacrificial layer deposited on a substrate. A portion of the barrier layer is removed to form an etched structure defined as a trench. An epi-polysilicon cap layer is epitaxially growth on the barrier layer and the entire etched structure. A portion of the epi-polysilicon cap layer has been removed to form a plurality of openings. The sacrificial layer is etched away leaving a cavity below the etched openings. A refill epi-polysilicon layer is epitaxially grown in the openings and seals the entire openings after a gap is formed between the cap layer and the substrate.

Claim (Index 6):
The MEMS device of  claim 5  wherein a vHF released cavity between the barrier layer and the substrate is formed after a portion of the sacrificial layer is dissolved.
