  • Publication number: 20090029501
    Abstract: A method of forming a microphone forms a backplate, and a flexible diaphragm on at least a portion of a wet etch removable sacrificial layer. The method adds a wet etch resistant material, where a portion of the wet etch resistant material is positioned between the diaphragm and the backplate to support the diaphragm. Some of the wet etch resistant material is not positioned between the diaphragm and backplate. The method then removes the sacrificial material before removing any of the wet etch resistant material added during the prior noted act of adding. The wet etch resistant material then is removed substantially in its entirety after removing at least part of the sacrificial material.

  • Publication number: 20090014837
    Abstract: The present invention relates to a semiconductor device and a method of manufacturing the same. A high-resistance silicon wafer is manufactured in such a manner that a large-sized silicon wafer manufactured by the Czochralski method is irradiated with neutrons, and high-resistance and low-resistance elements are simultaneously formed on the high-resistance silicon wafer. Thus, the manufacturing cost can be remarkably saved, and the reliability of products can be enhanced.

  • Publication number: 20080258182
    Abstract: A BiCMOS-compatible JFET device comprising source and drain regions (17, 18) which are formed in the same process as that used to form the emitter out-diffusion or a vertical bipolar device, wherein the semiconductor layer which forms the emitter cap in the bipolar device forms the channel (16) of the JFET device and the layer of material (i.e. the base epi-stack) which forms the intrinsic base region of the bipolar device forms the intrinsic gate region (14) of the JFET device. As a result, the integration of the JFET device into a standard BiCMOS process can be achieved without the need for any additional masking or other processing steps.

  • Patent number: 7078320
    Abstract: Disclosed is a method of manufacturing integrated circuit chips that partially joins an integrated circuit wafer to a supporting wafer at a limited number of joining points. Once joined, the integrated circuit wafer is chemically-mechanically polished to reduce the thickness of the integrated circuit wafer. Then, after reducing the thickness of the integrated circuit wafer, the invention performs conventional processing on the integrated circuit wafer to form devices and wiring in the integrated circuit wafer. Next, the invention cuts through the integrated circuit wafer and the supporting wafer to form chip sections. During this cutting process, the integrated circuit wafer separates from the supporting wafer in chip sections where the integrated circuit wafer is not joined to the supporting wafer by the joining points.
