  • Patent number: 8084361
    Abstract: A method includes depositing a layer of a sacrificial material in a first region above a substrate. The first region of the substrate is separate from a second region of the substrate, where a corrosion resistant film is to be provided above the second region. The corrosion resistant film is deposited, so that a first portion of the corrosion resistant film is above the sacrificial material in the first region, and a second portion of the corrosion resistant film is above the second region. The first portion of the corrosion resistant film is removed by chemical mechanical polishing. The sacrificial material is removed from the first region using an etching process that selectively etches the sacrificial material, but not the corrosion resistant film.

  • Patent number: 7696766
    Abstract: A system and a method of testing a semiconductor die is provided. An embodiment comprises a plurality of tips that each comprise a substrate with a conductive via, a first dielectric layer with vias connected to the conductive via, a second dielectric layer with vias over the first dielectric layer, and a metal layer over the second dielectric layer. Additional dielectric layers with vias may be used. This tip is electrically connected to a redistribution line that routes signals between the tip to electrical connections on a space transformation layer. The space transformation layer is electrically connected to a printed circuit board using, for example, a spring loaded connection such as a pogo pin. The space transformation layer is aligned onto the printed circuit board by a series of guidance mechanisms such as guide pins or smooth fixtures, and the planarity of the tips is adjusted by adjusting the screws.

  • Publication number: 20060189023
    Abstract: A method of making a MEMS device including providing a first substrate with an insulator layer thereon. A holder is attached to the insulator layer, and the first substrate is thinned. Thereafter, cavities are formed in the first substrate and the first substrate is flipped over and bonded to an integrated circuit wafer with the cavities facing the integrated circuit wafer. The holder is removed to provide a first substrate with cavities formed therein facing the integrated circuit wafer and an insulator layer overlying the first substrate.

  • Publication number: 20050029221
    Abstract: A process for etching deep trenches in a substrate for purposes such as the fabrication of microelectromechanical systems (MEMS), for example, on the substrate. The two-step process includes first etching a tapered trench having a tapered profile and enhanced sidewall passivation in a substrate along a protective mask which defines the desired trench profile on the substrate surface. Next, the tapered trench is trimmed by high-density plasma in an isotropic etching step to provide a straight-profile deep trench with minimum sidewall passivation.

  • Patent number: 6679064
    Abstract: A wafer transfer system having a temperature control apparatus. The temperature control apparatus is constructed and arranged so that a material, element, or atomic particle may flow therethrough to heat or cool a wafer carried by the wafer transfer system. The material, element or atomic particle flowing through the temperature control apparatus causes heat to be pumped to or from an upper surface or lower surface. Preferably the temperature control apparatus is a thermoelectric device. Preferably the thermoelectric device includes a plurality of alternating N-type and P-type semiconductor pellets arranged electrically in series and thermally in parallel, and connected to a DC power supply.
