  • Patent number: 10600799
    Abstract: When a memory cell is formed over a first fin and a low breakdown voltage transistor is formed over a second fin, the depth of a first trench for dividing the first fins in a memory cell region is made larger than that of a second trench for dividing the second fins in a logic region. Thereby, in the direction perpendicular to the upper surface of a semiconductor substrate, the distance between the upper surface of the first fin and the bottom surface of an element isolation region in the memory cell region becomes larger than that between the upper surface of the second fin and the bottom surface of the element isolation region in the logic region.

  • Patent number: 10410957
    Abstract: Field-effect transistor (FET) devices are described herein that include one or more body contacts implemented near source, gate, drain (S/G/D) assemblies to improve the influence of a voltage applied at the body contact on the S/G/D assemblies. For example, body contacts can be implemented between S/G/D assemblies rather than on the ends of such assemblies. This can advantageously improve body contact influence on the S/G/D assemblies while maintaining a targeted size for the FET device.

  • Patent number: 10262990
    Abstract: A robust electrostatic (ESD) protection device is provided. In one example, the ESD protection device is configured to accommodate three nodes. When used with a differential signal device, the first and second nodes may be coupled with the differential signal device's BP and BM signal lines, respectively, and the third node may be coupled to a voltage source. This allows for a single ESD protection device to be used to protect the signal lines of the differential signal device, thus providing significant substrate area savings as compared to the conventional means of using three dual-node ESD protection devices to accomplish substantially the same protection mechanism. Moreover, the ESD protection device may be structurally designed to handle high voltage ESD events, as required by the FlexRay standard.

  • Patent number: 10204789
    Abstract: Over a semiconductor substrate, a memory gate electrode for a nonvolatile memory cell is formed via a first insulating film having an internal charge storage portion. A dummy control gate electrode is formed so as to be adjacent to the memory gate electrode via a second insulating film. The memory and the dummy control gate electrodes are made of different materials. A third insulating film is formed so as to cover the memory and the dummy control gate electrodes and then polished to expose the memory and the dummy control gate electrodes. Then, etching is performed under a condition in which the memory gate electrode is less likely to be etched than the dummy control gate electrode to remove the dummy control gate electrode. Then, in a trench as a region from which the dummy control gate electrode is removed, a control gate electrode for the memory cell is formed.
