  • Publication number: 20080200020
    Abstract: A method is proposed for the fabrication of the gate electrode of a semiconductor device such that the effects of gate depletion are minimized. The method is comprised of a dual deposition process wherein the first step is a very thin layer that is doped very heavily by ion implantation. The second deposition, with an associated ion implant for doping, completes the gate electrode. With the two-deposition process, it is possible to maximize the doping at the gate electrode/gate dielectric interface while minimizing risk of boron penetration of the gate dielectric. A further development of this method includes the patterning of both gate electrode layers with the advantage of utilizing the drain extension and source/drain implants as the gate doping implants and the option of offsetting the two patterns to create an asymmetric device.

  • Publication number: 20080191196
    Abstract: The present invention generally relates to nanoscale heterostructures and, in some cases, to nanowire heterostructures exhibiting ballistic transport, and/or to metal-semiconductor junctions that that exhibit no or reduced Schottky barriers. One aspect of the invention provides a solid nanowire having a core and a shell, both of which are essentially undoped. For example, in one embodiment, the core may consist essentially of undoped germanium and the shell may consist essentially of undoped silicon. Carriers are injected into the nanowire, which can be ballistically transported through the nanowire. In other embodiments, however, the invention is not limited to solid nanowires, and other configurations, involving other nanoscale wires, are also contemplated within the scope of the present invention. Yet another aspect of the invention provides a junction between a metal and a nanoscale wire that exhibit no or reduced Schottky barriers.

  • Patent number: 7335590
    Abstract: In a method of fabricating a semiconductor device by selectively forming a diffusion barrier layer, and a semiconductor device fabricated thereby, a conductive pattern and an insulating layer, which covers the conductive pattern, are formed on a semiconductor substrate. The insulating layer is patterned, thereby forming an opening for exposing at least a portion of the conductive pattern. Then, a diffusion barrier layer is formed on the semiconductor substrate having the opening, using a selective deposition technique. The diffusion barrier layer is formed to a thickness that is less on the exposed conductive pattern than the thickness of the diffusion barrier layer on the insulating layer exposed inside the opening. Then, the diffusion barrier layer is etched, thereby forming a recessed diffusion barrier layer. In this manner, metal atoms are prevented from being diffused from a metal plug filling the opening or a metal interconnect to the insulating layer.

  • Patent number: 7314835
    Abstract: A method for depositing a film on a substrate using a plasma enhanced atomic layer deposition (PEALD) process includes disposing the substrate in a process chamber configured to facilitate the PEALD process. A first process material is introduced within the process chamber, and a second process material is introduced within the process chamber. Electromagnetic power of more than 600 W is coupled to the process chamber during introduction of the second process material in order to generate a plasma that accelerates a reduction reaction between the first and second process materials at a surface of the substrate. The film is formed on the substrate by alternatingly introducing the first process material and the second process material.

  • Patent number: 7300815
    Abstract: Described is a process to pattern adhesion and top contact layers in such a way that at least some portion of the top contact layers overlaps the adhesion layer, while another portion of the top contact layer overlaps with the bottom contacts, but does not overlap with the adhesion layer. The overlap between the top contact layer and the adhesion layer helps to hold the top contact layer onto the sacrificial layer. Because there is no overlap between the adhesion layer and the bottom contact, the removal of adhesion layer is no longer necessary, leading to better contacts and simplifying the fabrication process.

  • Publication number: 20070040277
    Abstract: A method and structure for suppressing localized metal precipitate formation (LMPF) in semiconductor processing. For each metal wire that is exposed to the manufacturing environment and is electrically coupled to an N region, at least one P+ region is formed electrically coupled to the same metal wire. As a result, few excess electrons are available to combine with metal ions to form localized metal precipitate at the metal wire. A monitoring ramp terminal can be formed around and electrically disconnected from the metal wire. By applying a voltage difference to the metal wire and the monitoring ramp terminal and measuring the resulting current flowing through the metal wire and the monitoring ramp terminal, it can be determined whether localized metal precipitate is formed at the metal wire.
