    Abstract: One embodiment is a method for semiconductor processing. In this method, a precursor film is provided over a semiconductor substrate, where the precursor film is made of a structural former and porogen. Prior to cross-linking, the porogen is removed by exposure to UV radiation having one or more wavelengths in the range of 150 nm to 300 nm, while a temperature of 300° C. to 500° C. is applied to the semiconductor substrate. Meanwhile, a Argon:Helium flow rate of 80>Ar>10 slm, 80>He>10 slm is set for the ambient substrate environment where the ratio of Ar:He ranges from 0:1 to 1:0 by volume or molality.

    Abstract: A structure includes a gate stack over a semiconductor region, a source/drain region on a side of the gate stack, a contact etch stop layer over a part of the source/drain region, an inter-layer dielectric over the contact etch stop layer, a silicide region over the source/drain region, a source/drain contact plug over and contacting the silicide region, and an isolation layer encircling the source/drain contact plug. In a top view of the source/drain contact plug, the source/drain contact plug is elongated, and the isolation layer includes an end portion at an end of the source/drain contact plug, and a middle portion between opposing ends of the source/drain contact plug. An end-portion thickness of the end portion is greater than a middle-portion thickness of the middle portion.

    Abstract: A representative method includes forming a photo-sensitive material over a substrate, and forming a cap layer over the photo-sensitive material, and patterning the cap layer. Using the patterned cap layer, a first portion of the photo-sensitive material is selectively exposed to a pre-selected light wavelength to change at least one material property of the first portion of the photo-sensitive material, while preventing a second portion of the photo-sensitive material from being exposed to the pre-selected light wavelength. One, but not both of the following steps is then conducted: removing the first portion of the photo-sensitive material and forming in its place a conductive element at least partially surrounded by the second portion of the photo-sensitive material, or removing the second portion of the photo-sensitive material and forming from the first portion of the photo-sensitive material a conductive element electrically connecting two or more portions of a circuit.
