Abstract:
1. A method of forming a sacrificial layer used to form a suspended element on a substrate, comprising: depositing a resin on a substrate; forming the resin according to a lithography process to provide a lithographed resist pattern on a zone of the substrate, the zone having a size and form determined by a resonance frequency range for the suspended element and the resin, the pattern occupying a volume in accordance with the resonance frequency range and the resin; annealing the lithographed resist pattern to form the lithographed resin into a profile in accordance with a thermal cycle thereof, the profile being one of a planarizing domed profile and a double air gap profile, wherein the resonance frequency range determines an interval separating the suspended element from said substrate zone, the resin being chosen to provide said interval.
