  • Patent number: 9508708
    Abstract: An integrated circuit containing a metal gate transistor and a thin polysilicon resistor may be formed by forming a first layer of polysilicon and removed it in an area for the thin polysilicon resistor. A second layer of polysilicon is formed over the first layer of polysilicon and in the area for the thin polysilicon resistor. The thin polysilicon resistor is formed in the second layer of polysilicon and the sacrificial gate is formed in the first layer of polysilicon and the second layer of polysilicon. A PMD layer is formed over the second layer of polysilicon and a top portion of the PMD layer is removed so as to expose the sacrificial gate but not expose the second layer of polysilicon in the thin polysilicon resistor. The sacrificial gate is removed and a metal replacement gate is formed.

  • Patent number: 8405154
    Abstract: An integrated circuit is disclosed having symmetric and asymmetric MOS transistors of the same polarity, oriented perpendicularly to each other, formed by concurrent halo ion, LDD ion and/or S/D ion implant processes using angled, rotated sub-implants which vary the tilt angle, dose and/or energy between rotations. Implanted halo, LDD and/or S/D source and drain regions formed by angled subimplants may have different extents of overlap with, or lateral separation from, gates of the two types of transistors, producing transistors with two different sets of electrical properties. A process for concurrently fabricating the two types of transistors is also disclosed. Specific embodiments of processes for concurrently forming symmetric and asymmetric transistors are disclosed.

  • Patent number: 8294243
    Abstract: Conduction between source and drain or emitter and collector regions is an important characteristic in transistor operation, particularly for lateral bipolar transistors. Accordingly, techniques that can facilitate control over this characteristic can mitigate yield loss by promoting the production of transistors that have an increased likelihood of exhibiting desired operational performance. As disclosed herein, well regions are established in a semiconductor substrate to facilitate, among other things, control over the conduction between the source and drain regions of a lateral bipolar transistor, thus mitigating yield loss and other associated fabrication deficiencies. Importantly, an additional mask is not required in establishing the well regions, thus further mitigating (increased) costs associated with promoting desired device performance.
