Abstract
A method of forming spring structures using a single lithographic operation is described. In particular, a single lithographic operation both defines the spring area and also defines what areas of the spring will be uplifted. By eliminating a second lithographic operation to define a spring release area, processing costs for spring fabrication can be reduced.
