  • Patent number: 12628411
    Abstract: A method of manufacturing a semiconductor device includes forming a stack of epitaxially grown layers alternating between a first semiconductor material and a second semiconductor material that is etch selective to the first semiconductor material. Fin structures are formed from the stack. The fin structures include channel structures formed of the first semiconductor material. The channel structures have opposing ends that are uncovered. Sidewall constraints are formed at the opposing ends of the channel structures. Each pair of the sidewall constraints laterally bounds a respective source/drain (S/D) region at a respective end of the channel structures while having a respective top opening for accessing the respective S/D region. S/D structures are formed on the opposing ends of the channel structures by epitaxially growing a third semiconductor material between each pair of the sidewall constraints.

  • Patent number: 12622180
    Abstract: Reciprocal quantum logic (RQL) bias-level sensors are fabricated on an RQL integrated circuit (IC) to sample AC or DC bias values provided to operational RQL circuitry on the RQL IC. The bias-level sensors, or samplers, include Josephson transmission lines (JTLs) or logic gates having strengthened or weakened bias taps as compared to bias taps of JTLs or logic gates in the operational RQL circuitry. Sampler JTLs or logic gates with weakened bias taps to AC clock resonators can have lower limits of their operational ranges placed near an optimal bias point at the centroid of the operating region of the operational RQL circuitry. Staging relative strengths of the bias taps of the samplers in an ensemble of samplers allows for outputs of wrapper circuitry to be indicative of whether a provided bias value is an improvement or optimization of the bias value when varied over a range.
