438253, 438396, 257E21008
Abstract:
The invention relates to a stacked capacitor () comprising a silicon base plate (), a poly-silicon center plate () arranged above the base plate (), a lower gate-oxide dielectric () arranged between the base plate () and the center plate (), a cover plate () made of a metallic conductor and arranged above the center plate (), and an upper dielectric () arranged between the center plate () and the cover plate (). The cover plate () and the base plate () are electrically connected to each other and together form a first capacitor electrode. The center plate () forms a second capacitor electrode. The invention further relates to an integrated circuit with such a stacked capacitor, as well as to a method for fabrication of a stacked capacitor as part of a CMOS process.

Abstract:
An integrated BiCMOS semiconductor circuit has active moat areas in silicon. The active moat areas include electrically active components of the semiconductor circuit, which comprise active window structures for base and/or emitter windows. The integrated BiCMOS semiconductor circuit has zones where silicon is left to form dummy moat areas which do not include electrically active components, and has isolation trenches to separate the active moat areas from each other and from the dummy moat areas. The dummy moat areas comprise dummy window structures having geometrical dimensions and shapes similar to those of the active window structures for the base and/or emitter windows.

Badih El-Kareh - Cedar Park TX, US Hiroshi Yasuda - Munich, DE Scott Gerard Balster - Dallas TX, US Philipp Steinmann - Unterschleissheim, DE Joe R. Trogolo - Plano TX, US
An junction field effect transistor (JFET) is fashioned with a patterned layer of silicide block (SBLK) material utilized in forming gate, source and drain regions. Utilizing the silicide block in this manner helps to reduce low-frequency (flicker) noise associated with the JFET by suppressing the impact of surface states, among other things.

US Classification:
438189, 438190, 257133, 257131
Abstract:
An integrated circuit with gate self-protection comprises a MOS device and a bipolar device, wherein the integrated circuit further comprises a semiconductor layer with electrically active regions in which and on which the MOS device and the bipolar device are formed and electrically inactive regions for isolating the electrically active regions from each other. The MOS device comprises a gate structure and a body contacting structure, wherein the body contacting structure is formed of a base layer deposited in a selected region over an electrically active region of the semiconductor layer, and the body contacting structure is electrically connected with the gate structure. The base layer forming the body contacting structure also forms the base of the bipolar device. The present invention further relates to a method for fabricating such an integrated circuit.

Abstract:
An integrated semiconductor structure that has first and second bipolar transistor structures. The first bipolar transistor structure has a doped tank region in contact with a doped tank region located underneath a contacting sinker. The second bipolar transistor structure has a doped buried region that is the same dopant type as its doped tank region. A method for fabricating an integrated semiconductor structure in a bulk semiconductor wafer. A first patterned photomask is used to form a doped buried region and a doped tank region within the first bipolar transistor structure. A second patterned photomask is used to form a doped buried region and a doped tank region within the second bipolar transistor, plus a doped buried region and a doped tank region underneath a contacting sinker adjacent to the first bipolar transistor.
