    摘要: A semiconductor layout structure for an electrostatic discharge (ESD) protection circuit is disclosed. The semiconductor layout structure includes a first area, in which one or more devices are constructed for functioning as a silicon controlled rectifier, and a second area, in which at least one device is constructed for functioning as a trigger source that provides a triggering current to trigger the silicon controlled rectifier for dissipating ESD charges during an ESD event. The first area and the second area are placed adjacent to one another without having a resistance area physically interposed or electrically connected therebetween, such that the triggering current received by the silicon controlled rectifier is increased during the ESD event.

    摘要: A process for forming an isolation region comprised of shallow trench-deep trench configuration, wherein a smooth top surface topography is obtained for the isolation region and for adjacent active device regions in the semiconductor substrate, has been developed. The process features initially forming an insulator filled shallow trench shape, planarized via a first chemical mechanical polishing procedure, allowing reduced complexity to be realized during the subsequent formation of a narrow diameter, deep trench opening, in the insulator filled shallow trench shape and in an underlying portion of semiconductor substrate. Formation of a recessed polysilicon plug located in the bottom portion of the deep trench opening is followed by formation of an insulator plug located in a top portion of the deep trench opening, overlying the recessed polysilicon plug. This is accomplished via photolithographic and selective dry definition procedures, and a second chemical mechanical polishing procedure, resulting in a filled, deep trench opening exhibiting a smooth top surface topography.

    摘要: During the conventional manufacture of HBTs, implant damage occurs which leads to enhanced internal base diffusion. This problem has been overcome by making the base and base contact area from a single, uniformly doped layer of silicon-germanium. Instead of an ion implant step to selectively reduce the resistance of this layer away from the base, a layer of polysilicon is selectively deposited (using selective epi deposition) onto only that part. Additionally, the performance of the polysilicon emitter is enhanced by means a brief thermal anneal that drives a small amount of opposite doping type silicon into the SiGe base layer.

    摘要: A new method of forming simultaneously both shallow and deep trenches is described. A pad oxide layer is provided over a semiconductor substrate. A silicon nitride layer is deposited overlying the pad oxide layer. A silicon dioxide layer is deposited overlying the silicon nitride layer. A photoresist mask is formed over the silicon dioxide layer wherein the photoresist mask has a first opening having a first width and a second opening having a second width and wherein the second width is larger than the first width. Trench openings are etched through the silicon dioxide, silicon nitride, and pad oxide layers to the underlying semiconductor substrate within the first and second openings. The photoresist mask is removed. The substrate is etched into through the trench openings to form first and second trenches wherein the first trench within the first opening having the first width is a shallow trench having a first depth and wherein the second trench within the second opening having the second width is a deep trench having a second depth greater than the first depth completing the formation of shallow and deep trenches simultaneously in the fabrication of an integrated circuit.
