Abstract: Disclosed herein are transistor arrangements of field-effect transistors with dual thickness gate dielectrics. An example transistor arrangement includes a semiconductor channel material, a source region and a drain region, provided in the semiconductor material, and a gate stack provided over a portion of the semiconductor material that is between the source region and the drain region. The gate stack has a thinner gate dielectric in a portion that is closer to the source region and a thicker gate dielectric in a portion that is closer to the drain region, which may effectively realize tunable ballast resistance integrated with the transistor arrangement and may help increase the breakdown voltage and/or decrease the gate leakage of the transistor.

Abstract: Embodiments herein relate to a temperature-sensing circuit for a semiconductor device. The circuit has a remote temperature-sensing element (RTSE) including a metal thermistor formed in a metal layer on the front side or backside of a substrate. The metal thermistor may be serpentine or spiral shaped. The RTSE communicates with a separate sense circuit at another location such as on the substrate. The RTSE can further include a thin film resistor (TFR) in an adjacent dielectric layer of the stack or within the sense circuit. The RTSE is driven alternately at opposing ends to cancel out the effects of power supply variations. An output voltage which represents a sensed temperature is obtained from a point between the metal thermistor and the TFR for processing by an analog-to-digital converter.

Abstract: An integrated circuit structure includes a sub-fin having (i) a first portion including a p-type dopant and (ii) a second portion including an n-type dopant. A first body of semiconductor material is above the first portion of the sub-fin, and a second body of semiconductor material is above the second portion of the sub-fin. In an example, the first portion of the sub-fin and the second portion of the sub-fin are in contact with each other, to form a PN junction of a diode. For example, the first portion of the sub-fin is part of an anode of the diode, and wherein the second portion of the sub-fin is part of a cathode of the diode.
