  • Patent number: 10700219
    Abstract: A method for manufacturing a semiconductor component includes forming first mesa and second mesa structures from a semiconductor material by etching trenches into the semiconductor material. A doped region having a multi-concentration dopant profile is formed in at least the first mesa structure and doped polysilicon is formed in the trenches. The trenches are formed in a geometric pattern. A contact having three contact types is formed, wherein a first contact type is formed to the first mesa structure, a second contact type is formed to the second mesa structure, and a third contact type is formed to the doped polysilicon in the trenches. The first contact type has electrical properties between a conventional Schottky contact and a conventional Ohmic contact without being a conventional Schottky contact or a conventional Ohmic contact, the second contact type is a Schottky contact, the third contact type is an Ohmic contract.

  • Publication number: 20200013717
    Abstract: A vertical OTP fuse formed in a semiconductor device has a substrate and an insulating layer formed over the substrate with an opening through the insulating layer extending to the substrate. A conductive layer, such as silicide, is formed over a sidewall of the opening. A resistive material, such as polysilicon, is deposited within the opening over the first conductive layer to form a first vertical OTP fuse. A plurality of vertical OTP fuses can be arranged in an array. A PN junction diode or transistor is formed in the substrate aligned with the first vertical OTP fuse. A second conductive layer is formed over the first vertical OTP fuse. The first vertical OTP fuse can be disposed between the second conductive layer and a third conductive layer. A second vertical OTP fuse can be formed over the first vertical OTP fuse for redundancy.
