  • Patent number: 8436635
    Abstract: A semiconductor wafer includes a plurality of die areas including circuit elements, and at least one test module (TM) on the wafer outside the die areas. The TMs include a test circuit including plurality of test transistors arranged in a plurality of rows and columns. The plurality of test transistors include at least three terminals (G, S, D and B). The TMs each include a plurality of pads. The pads include a first plurality of locally shared first pads each coupled to respective ones of a first of the three terminals, a second plurality of locally shared second pads each coupled to respective ones of a second of the three terminals, and at least one of the plurality of pads coupled to a third of the three terminals. The TM provides at least 2 pin transistor selection for uniquely selecting from the plurality of test transistors for testing.

  • Patent number: 7268394
    Abstract: Junction field effect transistors (JFETs) can be fabricated with an epitaxial layer that forms a sufficiently thick channel region to enable the JFET for use in high voltage applications (e.g., having a breakdown voltage greater than about 20V). Additionally or alternatively, threshold voltage (VT) implants can be introduced at one or more of the gate, source and drain regions to improve noise performance of the JFET. Additionally, fabrication of such a JFET can be facilitated forming the entire JFET structure concurrently with a CMOS fabrication process and/or with a BiCMOS fabrication process.

  • Patent number: 7018880
    Abstract: The present invention provides, in one embodiment, a method of reducing 1/f noise in a metal oxide semiconductor (MOS) device (100). The method comprises forming an oxide layer (110) on a silicon substrate (105) and depositing a polysilicon layer (115) on the oxide layer (110). The method further includes implanting a fluorine dopant (130) into the polysilicon layer (115) at an implant dose of at least about 4×1014 atoms/cm2. The polysilicon layer (115) is thermally annealed such that a portion of the fluorine dopant (130) is diffused into the oxide layer (110) to thereby reduce a 1/f noise of the MOS device (100). Other embodiments of the provide a MOS device (300) manufactured by the above-described method and a method of manufacturing an integrated circuit (500) that includes the above-described method.
