    摘要: The present invention relates to a semiconductor device that contains a trench metal-insulator-metal (MIM) capacitor and a field effect transistor (FET), and a design structure including the semiconductor device embodied in a machine readable medium. The trench MIM capacitor comprises a first metallic electrode layer located over interior walls of a trench in a substrate, a dielectric layer located in the trench over the first metallic electrode layer, and a second metallic electrode layer located in the trench over the dielectric layer. The FET comprises a source region, a drain region, a channel region between the source and drain regions, and a gate electrode over the channel region. The trench MIM capacitor is connected to the FET by a metallic strap. The semiconductor device of the present invention can be fabricated by a process in which the trench MIM capacitor is formed after the FET source/drain region but before the FET source/drain metal silicide contacts, for minimizing metal contamination in the FET.

    摘要: The present invention relates to a semiconductor device that contains at least one trench metal-oxide-metal (MIM) capacitor and at least one other logic circuitry component, preferably at least one field effect transistor (FET). The trench MIM capacitor is located in a trench in a substrate and comprises inner and outer metallic electrode layers with a dielectric layer therebetween. The FET comprises a source region, a drain region, a channel region, and at least one metal contact connected with the source or drain region. The present invention also relates to a fabrication process, which integrates the processing steps for fabricating the trench MIM capacitor with the conventional middle-of-line processing steps for fabricating metal contacts, so that the inner metallic electrode layer of the trench MIM capacitor and the metal contact of the FET or other logic circuitry components are formed by a single middle-of-line processing step and comprise essentially the same metallic material.

    摘要: A semiconductor structure and a method for forming the same. The structure includes (a) a substrate which includes semiconductor devices and (b) a first ILD (inter-level dielectric) layer on top of the substrate. The structure further includes N first actual metal lines in the first ILD layer, N being a positive integer. The N first actual metal lines are electrically connected to the semiconductor devices. The structure further includes first trenches in the first ILD layer. The first trenches are not completely filled with solid materials. If the first trenches are completely filled with first dummy metal lines, then (i) the first dummy metal lines are not electrically connected to any semiconductor device and (ii) the N first actual metal lines and the first dummy metal lines provide an essentially uniform pattern density of metal lines across the first ILD layer.

    摘要: A low-K value dielectric protection spacer for patterning through substrate vias (TSVs) through a low-K value wiring layer. A method for forming a low-K value dielectric protection spacer includes etching a via opening through a low-K value dielectric interconnect layer. A protective layer is deposited in the via opening and on the low-K value dielectric interconnect layer. At least a portion of the protective layer is etched from the bottom of the via opening and from a horizontal surface of the low-K value dielectric interconnect layer. The etching leaving a protective sidewall spacer on a sidewall of the via opening. A through substrate via is etched through the bottom of the via opening and through the semiconductor substrate. The through substrate via is filled with a conductive material.
