  • Patent number: 9779987
    Abstract: Aspects of the present invention relate to approaches for forming a narrow source-drain contact in a semiconductor device. A contact trench can be etched to a source-drain region of the semiconductor device. A titanium liner can be deposited in this contact trench such that it covers substantially an entirety of the bottom and walls of the contact trench. An x-metal layer can be deposited over the titanium liner on the bottom of the contact trench. A titanium nitride liner can then be formed on the walls of the contact trench. The x-metal layer prevents the nitriding of the titanium liner on the bottom of the contact trench during the formation of the nitride liner.

  • Patent number: 9721835
    Abstract: Recrystallization and grain growth of an interconnect metal, such as Cu, is achieved at higher anneal temperatures of 150° C. to 600° C., for example, for short anneal times of five to 180 minutes by forming a metal stress locking layer on the interconnect metal before anneal and chemical-mechanical polishing. The stress locking layer extends the elastic region of the interconnect metal by suppressing atom diffusion to the free surface, resulting in near zero tensile stress at room temperature after anneal. Stress voiding, which creates reliability problems, is thereby avoided. Improved grain size and texture are also achieved. The stress locking layer is removed after anneal by chemical-mechanical polishing or wet etching leaving the metal interconnect with low stress and improved grain size and texture. Annealing can be done in a forming gas or nitrogen gas atmosphere.

    Abstract: Provided are a low-cost semiconductor device manufacturing method and a semiconductor device made using the method. The method includes forming multiple body regions in a semiconductor substrate, forming multiple gate insulating layers and multiple gate electrodes in the body region; implementing a blanket ion implantation in an entire surface of the substrate to form a low concentration doping region (LDD region) in the body region without a mask, forming a spacer at a side wall of the gate electrode, and implementing a high concentration ion implantation to form a high concentration source region and a high concentration drain region around the LDD region. According to the examples, devices have favorable electrical characteristics and at the same time, manufacturing costs are reduced. Since, when forming high concentration source region and drain regions, tilt and rotation co-implants are applied, an LDD masking step is potentially omitted.
