  • Publication number: 20160204229
    Abstract: Embodiments of mechanisms for forming dislocations in source and drain regions of finFET devices are provided. The mechanisms involve recessing fins and removing the dielectric material in the isolation structures neighboring fins to increase epitaxial regions for dislocation formation. The mechanisms also involve performing a pre-amorphous implantation (PAI) process either before or after the epitaxial growth in the recessed source and drain regions. An anneal process after the PAI process enables consistent growth of the dislocations in the source and drain regions. The dislocations in the source and drain regions (or stressor regions) can form consistently to produce targeted strain in the source and drain regions to improve carrier mobility and device performance for NMOS devices.

  • Patent number: 9117843
    Abstract: An engineered epitaxial region compensates for short channel effects of a MOS device by providing a blocking layer to reduce or prevent dopant diffusion while at the same time reducing or eliminating the side effects of the blocking layer such as increased leakage current of a BJT device and/or decreased breakdown voltage of a rectifier. These side effects are reduced or eliminated by a non-conformal dopant-rich layer between the blocking layer and the substrate, which lessens the abruptness of the junction, thus lower the electric field at the junction region. Such a scheme is particularly advantageous for system on chip applications where it is desirable to manufacture MOS, BJT, and rectifier devices simultaneously with common process steps.
