  • Publication number: 20230352518
    Abstract: An integrated circuit die includes a silicon chromium (SiCr) thin film resistor disposed on a first oxide layer. The SiCr thin film resistor has a resistor body and a resistor head. A second oxide layer overlays the SiCr thin film resistor. The second oxide layer has an opening exposing a surface of the resistor head. A metal pad is disposed in the opening in the second oxide layer and is contact with the surface of the resistor head exposed by the opening. Further, an interlevel dielectric layer is disposed on the second oxide layer overlaying the SiCr thin film resistor. A metal-filled via extends from a top surface of interlevel dielectric layer through the interlevel dielectric layer and contacts the metal pad disposed in the opening in the second oxide layer.

  • Patent number: 11506687
    Abstract: In one embodiment, a method of forming a semiconductor device may include forming a sense resistor to receive a high voltage signal and form a sense signal that is representative of the high voltage signal. An embodiment of the sense resistor may optionally be formed overlying a polysilicon resistor. The method may also have an embodiment that may include forming a plurality of capacitors in parallel to portions of the sense resistor wherein the plurality of capacitors are connected together in series.

  • Publication number: 20220181462
    Abstract: In a general aspect, a transistor can include a fin having a proximal end and a distal end. The fin can include a dielectric portion longitudinally extending between the proximal end and the distal end, and a semiconductor layer disposed on the dielectric portion. The semiconductor layer can longitudinally extend between the proximal end and the distal end. The transistor can further include a source region disposed at the proximal end of the fin, and a drain region disposed at the distal end of the fin. The transistor can also include a gate dielectric layer disposed on a channel region of the semiconductor layer. The channel region can be disposed between the gate dielectric layer and the dielectric portion. The channel region can be longitudinally disposed between the source region and the drain region. The transistor can further include a conductive gate electrode disposed on the gate dielectric layer.
