Patent number: 7056783Abstract: An architecture for creating multiple operating voltage MOSFETs. Generally, an integrated circuit structure includes a semiconductor area with a major surface formed along a plane and first and second spaced-apart doped regions formed in the surface. A third doped region forming a channel of different conductivity type than the first region is positioned over the first region. A fourth doped region of a different conductivity and forming a channel is positioned over the second region. The process of creating the gate structure for each of the two transistors allows for the formation of oxide layers of different thickness between the two transistors. The transistors are therefore capable of operating at different operating voltages (including different threshold voltages). Each transistor further includes fifth and sixth layers positioned respectively over the third and fourth regions and having an opposite conductivity type with respect to the third and fourth regions.Type: GrantFiled: October 14, 2003Date of Patent: June 6, 2006Assignee: Agere Systems Inc.Inventors: Paul Arthur Layman, John Russell McMacken, J.

Patent number: 6759730Abstract: A structure and a process for fabricating a bipolar junction transistor (BJT) that is compatible with the fabrication of a vertical MOSFET is disclosed. In the process, at least three layers of material are formed sequentially on a semiconductor substrate, where the substrate includes a buried collector region for the BJT and a source region for the MOSFET. After the at least three layers are formed on the substrate, two windows or trenches are formed in the layers. The first window terminates at the surface of the silicon substrate where the source region has been formed; the second window terminates at the buried collector region. Both windows are then filled with semiconductor material. For the BJT, the bottom portion of the window is filled with material of a conductivity type matching the conductivity of the buried collector, while the upper region of the semiconductor material is doped the opposite conductivity to form the BJT base.Type: GrantFiled: September 18, 2001Date of Patent: July 6, 2004Assignee: Agere Systems Inc.Inventors: Samir Chaudhry, Paul Arthur Layman, John Russell McMacken, Ross Thomson, Jack Qingsheng Zhao
