  • Patent number: 10510743
    Abstract: An Electro-Static-Discharge (ESD) protection device has a Fin Field-Effect Transistor (FinFET) with a silicon fin with a step separating a top fin and a bottom fin. The gate wraps around the top fin but not the bottom fin. Normal gate-controlled channel conduction occurs in the top fin between a source and a drain in the top fin. Underneath the conducting channel is a buried conducting region in the bottom fin that conducts after a breakdown voltage is reached during ESD. A ledge, abrupt slope change in the sidewalls of the fin, or a doping increase occurs at the step between the top fin and bottom fin. The bottom fin is 2-3 times wider than the top fin, causing the resistance of the buried conducting region to be 2-3 times less than the resistance of the conducting channel, steering breakdown current away from the channel, reducing failures during breakdown.

  • Patent number: 10510876
    Abstract: A novel doping technology for semiconductor wafers has been developed, referred to as a “quantum doping” process that permits the deposition of only a fixed, controlled number of atoms in the form of a monolayer in a substitutional condition where only unterminated surface bonds react with the dopant, thus depositing only a number of atoms equal to the atomic surface density of the substrate material. This technique results in providing a “quantized” set of possible dopant concentration values that depend only on the additional number of layers of substrate material formed over the single layer of dopant atoms.

  • Patent number: 10490635
    Abstract: In a semiconductor substrate having a silicon carbide substrate and an epitaxial film, a concentration ratio between a hydrogen concentration in the silicon carbide substrate and a hydrogen concentration in the epitaxial film is in a range between 0.2 and 5, preferably in a range between 0.5 and 2. Thus, hydrogen diffusion at a boundary position between the epitaxial film and the SiC substrate is restricted. Further, it is possible to prepare the semiconductor substrate for restricting the reduction of the hydrogen concentration. Thus, it is possible to improve the properties of the SiC semiconductor device using the semiconductor substrate, for example, the bipolar device such as a PN diode.
