Apparatus and method for reducing slippage between structures in an interferometric modulator
First Claim
1. A method of making an electromechanical device, the method comprising:
- forming a substrate layer, the substrate layer comprising a first reflective surface;
etching at least a portion of a support region of the substrate layer to form a roughened support region; and
forming a support structure on the roughened support region of the substrate layer;
the roughened support region being configured to increase adhesion between the substrate layer and the support structure.

Abstract
A support structure within an interferometric modulator device may contact various other structures within the device. Increased bond strengths between the support structure and the other structures may be achieved in various ways, such as by providing roughened surfaces and/or adhesive materials at the interfaces between the support structures and the other structures. In an embodiment, increased adhesion is achieved between a support structure and a substrate layer. In another embodiment, increased adhesion is achieved between a support structure and a moveable layer. Increased adhesion may reduce undesirable slippage between the support structures and the other structures to which they are attached within the interferometric modulator.
