    摘要: A semiconducting device with a dual sidewall spacer and method of forming are provided. The method includes: depositing a first spacer layer over a patterned structure, the first spacer layer having a seam propagating through a thickness of the first spacer layer near an interface region of a surface of the substrate and a sidewall of the patterned structure, etching the first spacer layer to form a residual spacer at the interface region, where the residual spacer coats less than the entirety of the sidewall of the patterned structure, depositing a second spacer layer on the residual spacer and on the sidewall of the patterned structure not coated by the residual spacer, the second spacer layer being seam-free on the seam of the residual spacer, and etching the second spacer layer to form a second spacer coating the residual spacer and coating the sidewall of the patterned structure not coated by the residual spacer.

    摘要: A method of forming a semiconductor structure may include forming a semiconductor substrate having an array region and a support region, forming a semiconductor substrate and a gate stack over the support region of the substrate and applying a critical mask over the support region and the array region. The critical mask may have a first opening at an area corresponding to the array region and a second opening at an area corresponding to the support region. Contact holes may be formed in a glass layer at areas corresponding to the first and second opening. After removing the critical mask, a first blockout mask may be applied over the array region and a first conductive type dopant may be added to exposed polysilicon corresponding to openings of the blockout mask or gate contacts may be formed.

    摘要: The stresses commonly induced in the dielectrics of integrated circuits manufactured using metal patterning methods, such as reactive ion etching (RIE) and damascene techniques, can be reduced by rounding the lower corners associated with the features which are formed as part of the integrated circuit (e.g., the interconnects) before applying the outer (i.e., passivation) layer. In connection with the formation of metal lines patterned by a metal RIE process, such corner rounding can be achieved using a two-step metal etching process including a first step which produces a vertical sidewall and a second step which tapers lower portions of the vertical sidewall or which produces a tapered spacer along the lower portions of the vertical sidewall. This results in a rounded bottom corner which improves the step coverage of the overlying dielectric, in turn eliminating the potential for cracks. For metal lines patterned by damascene, such corner rounding can be achieved using a two-step trench etching process including a first step which produces a vertical sidewall, and a second step which produces a tapered sidewall along lower portions of the vertical sidewall.
