  • Publication number: 20080299769
    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.

  • Publication number: 20080180123
    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.

    Abstract: A method and a structure are provided for preventing lift-off of a semiconductor monitor pattern from a substrate . A semiconductor structure and a semiconductor monitor structure are formed on a substrate. A material layer is formed covering the semiconductor monitor structure. A part of the semiconductor structure is removed without removing the semiconductor monitor structure, by using the material layer as an etch protection layer. A mask for the method is also provided. The mask includes a clear area and a dark area. The dark area prevents a semiconductor monitor structure from being subjected to exposure so as to form a material layer covering the semiconductor monitor structure and prevent removal of the semiconductor monitor structure from the substrate while a part of a semiconductor structure is removed.
