    Abstract: An imprint lithography stamp includes a stamp body having a patterned surface and formed from a fluorinated ethylene propylene copolymer. The imprint lithography stamp further includes a backing plate with a plurality of through-holes with portions of the stamp body extending into the through-holes to adhere the stamp body to the backing plate. The patterned surface of the stamp body has a plurality of protrusions extending from the stamp body, which are used to form high aspect ratio features at high processing temperatures. A mold design for forming the imprint lithography stamp and an injection molding process for forming the imprint lithography stamp are also provided.

    Abstract: The present disclosure generally relates to apparatus and methods for forming a low-k dielectric material on a substrate. The method includes various substrate processing steps utilizing a wet processing chamber, a solvent exchange chamber, and a supercritical fluid chamber. More specifically, a dielectric material in an aqueous solution may be deposited on the substrate and a solvent exchange process may be performed to prepare the substrate for a supercritical drying process. During the supercritical drying process, liquids present in the solution and remaining on the substrate from the solvent exchange process are removed via sublimation during the supercritical drying process. The resulting dielectric material formed on the substrate may be considered a silica aerogel which exhibits a very low k-value.

    Abstract: Method and apparatus for forming a patterned magnetic substrate are provided. A patterned resist is formed on a magnetically active surface of a substrate. An oxide layer is formed over the patterned resist by a flowable CVD process. The oxide layer is etched to expose portions of the patterned resist. The patterned resist is then etched, using the etched oxide layer as a mask, to expose portions of the magnetically active surface. A magnetic property of the exposed portions of the magnetically active surface is then modified by directing energy through the etched resist layer and the etched oxide layer, which are subsequently removed from the substrate.
