  • Patent number: 8946041
    Abstract: Embodiments for forming improved bipolar transistors are provided, manufacturable by a CMOS IC process. The improved transistor comprises an emitter having first and second portions of different depths, a base underlying the emitter having a central portion of a first base width underlying the first portion of the emitter, a peripheral portion having a second base width larger than the first base width partly underlying the second portion of the emitter, and a transition zone of a third base width and lateral extent lying laterally between the first and second portions of the base, and a collector underlying the base. The gain of the transistor is larger than a conventional bipolar transistor made using the same CMOS process. By adjusting the lateral extent of the transition zone, the properties of the improved transistor can be tailored to suit different applications without modifying the underlying CMOS IC process.

  • Patent number: 8927420
    Abstract: Among other things, one or more support structures and techniques for forming such support structures within semiconductor devices are provided. The support structure comprises an oxide infused silicon layer that is formed within a trench of a dielectric layer on a substrate of a semiconductor device. The oxide infused silicon layer results from a silicon layer that is exposed to oxide during an ultraviolet (UV) curing process. The oxide infused silicon layer is configured to support a barrier layer against a conductive structure formed on the barrier layer within the trench. In this way, the support structure provides pressure against the barrier layer so that the barrier layer substantially maintains contact with the conductive structure, to promote improved performance and reliability of the conductive structure.

  • Patent number: 8900954
    Abstract: A method that forms a structure implants a well implant into a substrate, patterns a mask on the substrate (to have at least one opening that exposes a channel region of the substrate) and forms a conformal dielectric layer on the mask and to line the opening. The conformal dielectric layer covers the channel region of the substrate. The method also forms a conformal gate metal layer on the conformal dielectric layer, implants a compensating implant through the conformal gate metal layer and the conformal dielectric layer into the channel region of the substrate, and forms a gate conductor on the conformal gate metal layer. Additionally, the method removes the mask to leave a gate stack on the substrate, forms sidewall spacers on the gate stack, and then forms source/drain regions in the substrate partially below the sidewall spacers.

    Abstract: A first species is implanted into an entire surface of a workpiece and helium is implanted into this entire surface with a non-uniform dose. The first species may be, for example, hydrogen, helium, or nitrogen. The helium has a higher dose at a portion of a periphery of the workpiece. When the workpiece is split, this split is initiated at the periphery with the higher dose. The non-uniform dose may be formed by altering a scan speed of the workpiece or an ion beam current of the helium. In one instance, the non-uniform dose of the helium is larger than a uniform dose of the hydrogen.

    Abstract: An improved method of performing pocket or halo implants is disclosed. The amount of damage and defects created by the halo implant degrades the performance of the semiconductor device, by increasing leakage current, decreasing the noise margin and increasing the minimum gate voltage. The halo or packet implant is performed at cold temperature, which decreases the damage caused to the crystalline structure and improves the amorphization of the crystal. The use of cold temperature also allows the use of lighter elements for the halo implant, such as boron or phosphorus.

  • Patent number: 7488638
    Abstract: A method for fabricating integrable PMOSFET semiconductor structures in a P-doped substrate which are distinguished by a high dielectric strength is provided. In order to fabricate the PMOSFET semiconductor structure, a mask is applied to a semiconductor substrate for the definition of a window delimited by a peripheral edge. An N-doped well is thereupon produced in the P-doped semiconductor substrate by means of high-voltage ion implantation through the window delimited by the mask, the edge zone of said N-doped well reaching as far as the surface of the semiconductor substrate. The individual regions for the source, drain and bulk of the PMOSFET semiconductor structure are then produced in the P-doped inner zone enclosed by the well. The P-doped inner zone forms the drift zone of the PMOSFET structure. Since the drift zone has the weak basic doping of the substrate, the PMOSFET has a high dielectric strength.

  • Patent number: 7300851
    Abstract: A fabrication process for a silicon-on-insulator (SOI) device includes defining an active region in an 501 substrate, doping the entire active region with an impurity of a given conductive type, masking a main part of the active region, and doping the peripheral parts of the active region at least two additional times with an impurity of the same conductive type, preferably using different doping parameters each time. The additional, doping creates a channel stop in the peripheral parts of the active region, counteracting the tendency of the transistor threshold voltage to be lowered in the peripheral parts of the active region, thereby mitigating or eliminating the unwanted subthreshold hump often found in the transistor operating characteristics of, for example, fully depleted SOI devices.

  • Patent number: 7112499
    Abstract: A process is described to form a semiconductor device such as MOSFET or CMOS with shallow junctions in the source/drain extension regions. After forming the shallow trench isolations and the gate stack, sidewall dielectric spacers are removed. A pre-amorphizing implant (PAI) is performed with Ge+ or Si+ ions to form a thin PAI layer on the surface of the silicon regions adjacent to the gate stack. B+ ion implantation is then performed to form source/drain extension (SDE) regions. The B+ implant step is then followed by multiple-pulsed 248 nm KrF excimer laser anneal with pulse duration of 23 ns. This step is to reduce the sheet resistance of the junction through the activation of the boron dopant in the SDE junctions. Laser anneal is then followed by rapid thermal anneal (RTA) to repair the residual damage and also to induce out-diffusion of the boron to yield shallower junctions than the just-implanted junctions prior to RTA.

  • Patent number: 7112501
    Abstract: A fabrication process for a silicon-on-insulator (SOI) device includes defining an active region in an SOI substrate, doping the entire active region with an impurity of a given conductive type, masking a main part of the active region, and doping the peripheral parts of the active region at least two additional times with an impurity of the same conductive type, preferably using different doping parameters each time. The additional doping creates a channel stop in the peripheral parts of the active region, counteracting the tendency of the transistor threshold voltage to be lowered in the peripheral parts of the active region, thereby mitigating or eliminating the unwanted subthreshold hump often found in the transistor operating characteristics of, for example, fully depleted SOI devices.
