The method includes etching a source region and a drain region adjacent to the gate structure using the dielectric layer as a protective layer and depositing silicon germanium material into the source region and the drain region to fill the etched source region and the etched drain region. The method causes a channel region between the source region and the drain region to be strained in compressive mode from at least the silicon germanium material formed in the source region and the drain region. The method includes forming a second protective layer overlying surfaces and performing an anisotropic etching process to form spacer structures to seal the gate structure.

    摘要: A method of fabricating an MRAM device includes patterning a magnetic stack material layer (142) using a herd mask (146) formed by a “plate-through” technique. A resist (144) is deposited over magnetic stack material (142), and the resist (144) is patterned, exposing regions of the magnetic stack material (142). A hard mask (146) is formed over the magnetic stack material (142) exposed regions through the resist (144), and the hard mask (146) is used to pattern magnetic tunnel junctions (MTJ's) of the MRAM device. Electroplating, electro-less plating, sputtering, physical vapor deposition (PVD), evaporation deposition, or combinations thereof are used to deposit a material comprising a metal over the magnetic stack material (142) exposed regions to form the hard mask (146).
