  • Patent number: 9184095
    Abstract: In sophisticated semiconductor devices, the contact structure may be formed on the basis of contact bars formed in a lower portion of an interlayer dielectric material, which may then be contacted by contact elements having reduced lateral dimensions so as to preserve a desired low overall fringing capacitance.

  • Publication number: 20150228490
    Abstract: Performance and/or uniformity of sophisticated transistors may be enhanced by incorporating a carbon species in the active regions of the transistors prior to forming complex high-k metal gate electrode structures. For example, a carbon species may be incorporated by ion implantation into the active region of a P-channel transistor and an N-channel transistor after selectively forming a threshold adjusted semiconductor material for the P-channel transistor, while the active region of the N-channel transistor is still masked.

  • Patent number: 9087716
    Abstract: The present disclosure provides an improved method for forming a thin semiconductor alloy layer on top of a semiconductor layer. The proposed method relies on an implantation of appropriate impurity species before performing deposition of the semiconductor alloy film. The implanted species cause the semiconductor alloy layer to be less unstable to wet and dry etches performed on the device surface after deposition. Thus, the thickness uniformity of the semiconductor alloy film may be substantially increased if the film is deposited after performing the implantation. On the other hand, some implanted impurities have been found to decrease the growth rate of the semiconductor alloy layer. Thus, by selectively implanting appropriate impurities in predetermined portions of a wafer, a single deposition step may be used in order to form a semiconductor alloy layer with a thickness which may be locally adjusted at will.

  • Patent number: 9076815
    Abstract: A known problem when manufacturing transistors is the stress undesirably introduced by the spacers into the transistor channel region. In order to solve this problem, the present invention proposes an ion implantation aimed at relaxing the stress of the spacer materials. The relax implantation is performed after the spacer has been completely formed. The relax implantation may be performed after a silicidation process or after an implantation step in the source and drain regions followed by an activation annealing and before performing the silicidation process.
