Abstract

Official abstract text for this publication.

An actuator element of a MEMS device on a substrate able to create large, out-of-plane deflection includes two separated metallic layers contacting the substrate. The second metallic layer has a first portion contacting the substrate and a second portion having cantilevered over the substrate and first metallic layer. A first insulating layer contacts the cantilevered metallic layer on a bottom contacting surface and a second insulating layer contacting the cantilevered metallic layer on a portion of a top contacting surface. The second, cantilevered portion of the metallic layer is prestressed causing the distal end to deform away from the substrate. Applying a voltage potential between the first and second metallic layers creates an electrostatic field drawing the distal end toward the substrate.

First claim

Opening claim text (preview).

What is claimed is: 1 . An actuator element of a MEMS device on a substrate to create large, out-of-plane deflection, the actuator element comprising: a first metallic layer contacting the substrate; a second metallic layer having a first portion contacting the substrate separated from the first metallic layer and a second portion having an end proximal to the first portion and distal end cantilevered over the substrate and first metallic layer; a first insulating layer cont…
