摘要： A method is provided of forming a conductive via in contact with a bulk semiconductor region of a semiconductor-on-insulator (“SOI”) substrate. A first opening is formed in a conformal layer overlying a trench isolation region. The trench isolation region may share an edge with an SOI layer of the substrate. Desirably, a dielectric layer is deposited over a top surface of the conformal layer and the trench isolation region. A second opening can then be formed which extends through the dielectric layer and the first opening in the conformal layer. Desirably, portions of the bulk semiconductor region and the top surface of the conformal layer are exposed within the second opening. The second opening can then be filled with at least one of a metal or a semiconductor to form a conductive element contacting the exposed portions of the bulk semiconductor region and the top surface of the conformal layer.

摘要： Embodiments herein present a method for a feed forward suicide control scheme based on spacer height controlling pre-clean time. The method forms field effect transistor gates over a substrate and then forms spacers on the gates. Next, the method measures the spacers using an atomic force microscope to determine a measured spacer height. The method then conducts a pre-cleaning etch, wherein a duration of the pre-cleaning is adjusted according to the measured spacer height. If the measured spacer height is below a predetermined amount, the duration of the pre-cleaning is reduced; and, if the measured spacer height is above a predetermined amount, the duration of the pre-cleaning is increased.
