  • Patent number: 11380766
    Abstract: A transistor includes a quasi-intrinsic region of a first conductivity type that is covered with an insulated gate. The quasi-intrinsic region extends between two first doped regions of a second conductivity type. A main electrode is provided on each of the two first doped regions. A second doped region of a second conductivity type is position in contact with the quasi-intrinsic region, but is electrically and physically separated by a distance from the two first doped regions. A control electrode is provided on the second doped region.

  • Publication number: 20210317559
    Abstract: A method of forming an oxide layer in an in-situ steam generation (ISSG) process, including providing a silicon substrate in a rapid thermal process (RTP) chamber and injecting a gas mixture into the RTP chamber. The method further includes heating a surface of the silicon substrate to a reaction temperature, so that the gas mixture reacts close to the surface to form steam and thereby oxidize the silicon substrate to form the oxide layer on the surface, and wherein the gas mixture comprises hydrogen (H2), oxygen (O2) and nitrous oxide (N2O).

  • Patent number: 10211201
    Abstract: An ESD protection device includes a MOS transistor connected between a first terminal and a second terminal and having a gate region, source/drain region and a well region electrically coupled by a resistive-capacitive circuit configured to control turn on of the MOS transistor in response to an ESD event. The resistive-capacitive circuit has a common part with at least one of the source, gate or drain regions of the MOS transistor and includes a capacitive element and a resistive element. A first electrode of the capacitive element is formed by the resistive element and a second electrode of the capacitive element is formed by at least a portion of a semiconductor film within which the source/drain region is formed.
