  • Publication number: 20140246698
    Abstract: When forming sophisticated P-channel transistors, a semiconductor alloy layer is formed on the surface of the semiconductor layer including the transistor active region. When a metal silicide layer is formed contiguous to this semiconductor alloy layer, an agglomeration of the metal silicide layer into isolated clusters is observed. In order to solve this problem, the present invention proposes a method and a semiconductor device wherein the portion of the semiconductor alloy layer lying on the source and drain regions of the transistor is removed before formation of the metal silicide layer is performed. In this manner, the metal silicide layer is formed so as to be contiguous to the semiconductor layer, and not to the semiconductor alloy layer.

  • Patent number: 8772878
    Abstract: A silicon/germanium material and a silicon/carbon material may be provided in transistors of different conductivity type on the basis of an appropriate manufacturing regime without unduly contributing to overall process complexity. Furthermore, appropriate implantation species may be provided through exposed surface areas of the cavities prior to forming the corresponding strained semiconductor alloy, thereby additionally contributing to enhanced overall transistor performance. In other embodiments a silicon/carbon material may be formed in a P-channel transistor and an N-channel transistor, while the corresponding tensile strain component may be overcompensated for by means of a stress memorization technique in the P-channel transistor. Thus, the advantageous effects of the carbon species, such as enhancing overall dopant profile of P-channel transistors, may be combined with an efficient strain component while enhanced overall process uniformity may also be accomplished.
