  • Patent number: 7396749
    Abstract: The invention relates to a method for contacting parts of a component integrated into a semiconductor substrate (1). According to the inventive method, a first contact hole is produced in an insulating layer (2), said contact hole being then filled with contact material (16) and connected to a line. The aim of the invention is to minimise the processes required for contacting parts of a component integrated into a semiconductor substrate. To this end, the hard mask (3) used to produce the contact hole is also used to structure the line.

  • Patent number: 6835612
    Abstract: A gate layer stack formed with at least two layers is firstly patterned anisotropically and then thelower layer is etched. An isotropic, preferably selective etching step effects a lateral undercutting, i.e. removal of the lower layer as far as the predetermined channel length to form a dimensionally accurate T-gate transistor with a very short channel length.

  • Publication number: 20040157380
    Abstract: A gate layer stack formed with at least two layers is firstly patterned anisotropically and then the lower layer is etched. An isotropic, preferably selective etching step effects a lateral undercutting, i.e. removal of the lower layer as far as the predetermined channel length. This allows a T-gate transistor with a very short channel length to be fabricated dimensionally accurately, in a simple manner and cost-effectively. Its electrical switching properties are better than those of other T-gate transistors formed by conventional methods.
