Abstract:
The invention comprises a method for fabricating a monolithic chip containing integrated circuitry as well as a suspended polysilicon microstructure. The inventive method comprises 67 processes which are further broken down into approximately 330 steps. The processes and their arrangement allow for compatible fabrication of transistor circuitry and the suspended polysilicon microstructure on the same chip.
Abstract:
PURPOSE: A micro mechanical structure having an anti-adhesion layer and a fabricating method thereof are provided to reduce a process time and the generation of contamination by activating directly a surface of a substrate in a state of plasma. CONSTITUTION: A micro mechanical structure includes a substrate(100) and one or more moving structure(108) formed on the substrate. A passivation layer(110) is deposited on an entire surface of the micro mechanical structure by using a plasma chemical vapor deposition method. The passivation layer is formed with one ore more material selected from a group including fluorocarbon polymer, hydrocarbon polymer, hydrofluorocarbon polymer. The micro mechanical structure further includes one or more electrode formed on the substrate.
Abstract:
Systems and methods for providing MEMS devices with integrated desiccant are provided. In one embodiment, a dry composition comprising desiccant is impact sprayed onto the backplate or substrate of a MEMS device, and becomes fused with the substrate. In another embodiment, the desiccant is impact sprayed such that the desiccant adheres to the impact sprayed surface. In yet another embodiment, the impact- sprayed surface is impregnated with the desiccant. In still another embodiment, the desiccant is combined with a suitable inorganic binder, then impact sprayed such that the desiccant adheres to the impact sprayed surface. In yet a further embodiment, the desiccant is micronized or pulverized into a powder of desired particle size, and then impact sprayed onto a surface. Thus, the desiccant particles or powder are fused onto the target surface through the impact spraying process.

Abstract:
This invention disclosed a process for forming durable anti-stiction surfaces on micromachined structures while they are still in wafer form (i.e., before they are separated into discrete devices for assembly into packages). This process involves the vapor deposition of a material to create a low stiction surface. It also discloses chemicals which are effective in imparting an anti-stiction property to the chip. These include polyphenylsiloxanes, silanol terminated phenylsiloxanes and similar materials.
