  • Patent number: 11728383
    Abstract: A P-type field effect transistor (PFET) device and a method for fabricating a PFET device using fully depleted silicon on insulator (FDSOI) technology is disclosed. The method includes introducing germanium into the channel layer using ion implantation. This germanium implant increases the axial stress in the channel layer, improving device performance. This implant may be performed at low temperatures to minimize damage to the crystalline structure. Further, rather than using a long duration, high temperature anneal process, the germanium implanted in the channel layer may be annealed using a laser anneal or a rapid temperature anneal. The implanted regions are re-crystallized using the channel layer that is beneath the gate as the seed layer. In some embodiments, an additional oxide spacer is used to further separate the raised source and drain regions from the gate.

  • Patent number: 11646356
    Abstract: Describe is a resonator that uses anti-ferroelectric (AFE) materials in the gate of a transistor as a dielectric. The use of AFE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, additional current drive is also achieved from the piezoelectric response generated to due to AFE material. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above or below the AFE based transistor. Increased drive signal from the AFE results in larger output signal and larger bandwidth.

  • Patent number: 11637191
    Abstract: Describe is a resonator that uses ferroelectric (FE) materials in the gate of a transistor as a dielectric. The use of FE increases the strain/stress generated in the gate of the FinFET. Along with the usual capacitive drive, which is boosted with the increased polarization, FE material expands or contacts depending on the applied electric field on the gate of the transistor. As such, acoustic waves are generated by switching polarization of the FE materials. In some embodiments, the acoustic mode of the resonator is isolated using phononic gratings all around the resonator using the metal line above and vias' to body and dummy fins on the side. As such, a Bragg reflector is formed above the FE based transistor.
