  • Patent number: 9153684
    Abstract: In a replacement gate approach, the semiconductor material of the gate electrode structures may be efficiently removed during a wet chemical etch process, while this material may be substantially preserved in electronic fuses. Consequently, well-established semiconductor-based electronic fuses may be used instead of requiring sophisticated metal-based fuse structures. The etch selectivity of the semiconductor material may be modified on the basis of ion implantation or electron bombardment.

  • Patent number: 9082876
    Abstract: Integrated circuits and methods for fabricating integrated circuits are provided herein. In an embodiment of a method for fabricating integrated circuits, a P-type gate electrode structure and an N-type gate electrode structure are formed overlying a semiconductor substrate. The gate electrode structures each include a gate electrode that overlies a gate dielectric layer and a nitride cap that overlies the gate electrode. Conductivity determining ions are implanted into the semiconductor substrate using the P-type gate electrode structure and the N-type gate electrode structure as masks to form a source region and a drain region for the P-type gate electrode structure and the N-type gate electrode structure. The nitride cap remains overlying the N-type gate electrode structure during implantation of the conductivity determining ions into the semiconductor substrate to form the source region and the drain region for the N-type gate electrode structure.

  • 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.

  • Patent number: 9034744
    Abstract: In a replacement gate approach, the exposure of the placeholder material of the gate electrode structures may be accomplished on the basis of an etch process, thereby avoiding the introduction of process-related non-uniformities, which are typically associated with a complex polishing process for exposing the top surface of the placeholder material. In some illustrative embodiments, the placeholder material may be exposed by an etch process based on a sacrificial mask material.

  • Patent number: 9012956
    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: 8951877
    Abstract: When forming cavities in active regions of semiconductor devices in order to incorporate a strain-inducing semiconductor material, an improved shape of the cavities may be achieved by using an amorphization process and a heat treatment so as to selectively modify the etch behavior of exposed portions of the active regions and to adjust the shape of the amorphous regions. In this manner, the basic configuration of the cavities may be adjusted with a high degree of flexibility. Consequently, the efficiency of the strain-inducing technique may be improved.
