  • Patent number: 7776696
    Abstract: Making gates having multiple thicknesses on the same substrate in a given process flow is provided. For example, a method of making a semiconductor structure having at least two gates of different thickness involves forming a first gate layer having a first thickness; patterning a first hard mask over a portion of the first gate layer to define a first gate underneath the first hard mask having a first gate thickness; forming a second gate layer having a second thickness over the first gate layer and the first hard mask; patterning a second hard mask over a portion of the second gate layer to define a second gate underneath the second hard mask having a second gate thickness; removing portions of the first gate layer and the second gate layer that are not under the first hard mask and the second hard mask; and removing the first hard mask and the second hard mask to provide two gates of different thicknesses.

  • Publication number: 20100155789
    Abstract: A low noise (1/f) junction field effect transistor (JFET) is disclosed, wherein multiple implants push a conduction path of the transistor away from the surface of a layer upon which the transistor is formed. In this manner, current flow in the conduction path is less likely to be disturbed by defects that may exist at the surface of the layer, thereby mitigating (1/f) noise.

  • 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: 7084458
    Abstract: A method of fabricating a semiconductor device having a triple LDD (lateral diffused dopants) structure is disclosed. This fabrication method requires a single implant process, leading to reduction in fabrication costs and fabrication time. Moreover, this fabrication method increases the surface area of the gate structure of the semiconductor device that is available for silicide to be formed, leading to lower gate resistance.

  • Patent number: 6930005
    Abstract: A method for reducing the drain resistance of a drain-extended MOS transistor in a semiconductor wafer, while maintaining a high transistor breakdown voltage. The method provides a first well (502) of a first conductivity type, operable as the extension of the transistor drain (501) of the first conductivity type; portions of the well are covered by a first insulator (503) having a first thickness. A second well (504) of the opposite conductivity type is intended to contain the transistor source (506) of the first conductivity type; portions of the second well are covered by a second insulator (507) thinner than the first insulator. The first and second wells form a junction (505) that terminates at the second insulator (530a, 530b). The method deposits a photoresist layer (510) over the wafer, which is patterned by opening a window (510a) that extends from the drain to the junction termination.
