Abstract:
This disclosure provides systems, methods and apparatus for providing relatively thinner and less stiff compliant beams for a shutter assembly. A protective coating is deposited and patterned over the shutter assembly before it is released from a sacrificial mold over which the shutter assembly is formed. Because some primary surfaces of the compliant beams are in contact with the sacrificial mold, these primary surfaces are not coated with the protective coating. Therefore, when the shutter assembly is finally released, the resulting compliant beams are relatively thinner and less stiff providing a reduction in an actuation voltage used to operate the shutter assembly. In some instances, the protective coating is patterned into discontinuous segments before release.
