摘要:
The present application is directed to novel electrostatic actuators and methods of making the electrostatic actuators. In one embodiment, the electrostatic actuator comprises a substrate, an electrode formed on the substrate and a deflectable member positioned in proximity to the electrode so as to provide a gap between the electrode and the deflectable member. The deflectable member is anchored on the substrate via one or more anchors. The gap comprises at least one first region having a first gap height positioned near the one or more anchors and at least one second region having a second gap height positioned farther from the anchors than the first region. The first gap height is smaller than the second gap height.
摘要:
The present invention provides a micromechanical or microoptomechanical structure produced by a process comprising defining the structure in a single-crystal silicon layer separated by an insulator layer from a substrate layer; selectively etching the single crystal silicon layer; depositing and etching a polysilicon layer on the insulator layer, with remaining polysilicon forming mechanical elements of the structure; metalizing a backside of the structure; and releasing the formed structure.

The structure is produced by a process comprising defining a pattern on a single crystal silicon layer separated by an insulator layer from a substrate layer; defining a structure in the single-crystal silicon layer; depositing and etching a polysilicon layer on the single crystal silicon layer, with remaining polysilcon forming mechanical or optical elements of the structure; and releasing the formed structure.
摘要:
A micro-electromechanical fluid ejector having an inner structure on the bottom of the top of the membrane for isolating the conductor, and an outer structure, away from the center of the membrane, on the bottom of the top of the membrane to stop excessive flexing of the membrane leading to inter-electrode contact.
摘要:
A microstructure that may be used as an electrical connection in a microfabricated electro-mechanical system (MEMS) apparatus. The microstructure may have one or more isolatable electrical connections for signal transmission. The microstructure allows a MEMS apparatus to shield signal transmissions from the effects of electromagnetic interference or conductive fluids.
