| 20090096026 | METHOD OF FABRICATING HIGH VOLTAGE FULLY DEPLETED SOI TRANSISTOR AND STRUCTURE THEREOF - A method of fabricating a high voltage fully depleted silicon-on-insulator (FD SOI) transistor, the FD SOI transistor having a structure including a region within a body on which a gate structure is disposed. The region includes a channel separating the source region and the drain region. Above the source region is disposed a carrier recombination element, which abuts the gate structure and is electrically connected to the region via the channel. The drain region is lightly doped and ballasted to increase breakdown voltage. The FD SOI may be fabricated by forming a body with a thin silicon layer disposed on a buried oxide (BOX). Alternatively, the body may be formed using a partially depleted (PD) SOI where the region formed therein has a reduced thickness in comparison to the overall thickness of the PD SOI. | 04-16-2009 |
| 20090110023 | BOLOMETRIC ON-CHIP TEMPERATURE SENSOR - Disclosed are embodiments of an improved on-chip temperature sensing circuit, based on bolometry, which provides self calibration of the on-chip temperature sensors for ideality and an associated method of sensing temperature at a specific on-chip location.

The comparator is adapted to receive and compare the outputs from both the temperature and reference sensors and to drive the heater with current until the outputs match. Based on the current forced into the heater, the temperature rise of the reference sensor can be calculated, which in this state, is equal to that of the temperature sensor. | 04-30-2009 |

| 20090127595 | SEMICONDUCTOR STRUCTURE WITH FIELD SHIELD AND METHOD OF FORMING THE STRUCTURE - Disclosed is semiconductor structure that incorporates a field shield below a semiconductor device (e.g., a field effect transistor (FET) or a diode). The field shield is sandwiched between upper and lower isolation layers on a wafer. A local interconnect extends through the upper isolation layer and connects the field shield to a selected doped semiconductor region of the device (e.g., a source/drain region of a FET or a cathode or anode of a diode). Current that passes into the device, for example, during back-end of the line charging, is shunted by the local interconnect away from the upper isolation layer and down into the field shield. Consequently, an electric charge is not allowed to build up in the upper isolation layer but rather bleeds from the field shield into the lower isolation layer and into the substrate below. This field shield further provides a protective barrier against any electric charge that becomes trapped within the lower isolation layer or substrate | 05-21-2009 |
