摘要: An SOI transistor has a self-aligned body contact formed through an extension to the gate, thereby forming the body contact with minimal increase in area and also avoiding the need to tie the source to the body, as in prior art schemes that passed the body contact through the source. The body contact aperture is formed by raising the source and drain to define an initial aperture, depositing a conformal layer that is etched to create aperture-defining sidewalls and etching the contact aperture using these sidewalls to define sidewall support members that support insulating sidewalls to isolate the collection electrode from both the gate and from the source and drain.

摘要: A planarizing method involves a first polishing step in which a relatively hard, low compressibility pad removes excess material of a first layer and planarizes the first layer. Deep defects emanating from the polishing surface formed during the first polishing step are then enlarged and filled with a second layer. After filling, and optionally annealing, the second layer is planarized by polishing with a relatively soft and high compressibility pad or by anisotropic etching.

摘要: A method for fabricating microminiature, planar semiconductor devices in which the number of defects, in particular, pipes, is minimized. The thicknesses of the thermally grown silicon dioxide and of the silicon nitride masking layers which are used for the formation of limited impurity regions by high temperature diffusion processes within the semiconductor substrate have a specified, limited range. The thickness of the silicon dioxide is between 800A - 3000A and the thickness of the silicon nitride is between around 250A and 600A, preferably 500A. The method is particularly useful in forming extremely small emitter regions in bipolar transistors.

摘要: A structure, and a method for fabricating the structure, for the isolation of electronic devices is disclosed. The electronic devices are processed in substrates comprising a SiGe based layer underneath a strained Si layer. The isolation structure comprises a trench extending downward from the substrate top surface and penetrating into the SiGe based layer, forming a sidewall in the substrate. An epitaxial Si liner is selectively deposited onto the trench sidewall, and subsequently thermally oxidized. The trench is filled with a trench dielectric, which protrudes above the substrate top surface.
