  • Patent number: 11574867
    Abstract: An electrical fuse (e-fuse) includes a fuse link including a silicided semiconductor layer over a dielectric layer covering a gate conductor. The silicided semiconductor layer is non-planar and extends orthogonally over the gate conductor. A first terminal is electrically coupled to a first end of the fuse link, and a second terminal is electrically coupled to a second end of the fuse link. The fuse link may be formed in the same layer as an intrinsic and/or extrinsic base of a bipolar transistor. The gate conductor may control a current source for programming the e-fuse.

  • Patent number: 11574906
    Abstract: A number of monolithic multi-throw diode switch structures are described. The monolithic multi-throw diode switches can include a hybrid arrangement of diodes with different intrinsic regions, all formed over the same semiconductor substrate. In one example, two PIN diodes in a monolithic multi-throw diode switch have different intrinsic region thicknesses. The first PIN diode has a thinner intrinsic region, and the second PIN diode has a thicker intrinsic region. This configuration allows for both the thin intrinsic region PIN diode and the thick intrinsic region PIN diode to be individually optimized. As one example, for a switch functioning in a dedicated transmit/receive mode, the first transmit PIN diode can have a thicker intrinsic region than the second receive PIN diode to maximize power handling for the transmit arm and maximize receive sensitivity and insertion loss in the receive arm.
