Publication number: 20230259034Abstract: In a method, a resin layer of a stack (e.g., resin layer over sacrificial layer over transparent substrate) is imprinted to form a convex region including first region with first height and second region with second height <first height. Stack portions are etched around the convex region to expose a substrate portion. The stack is utilized to develop a curable layer to define a cured layer over the exposed substrate portion. The convex region and cured layer are etched. The resin layer and a sacrificial layer portion underlying the second region are removed. A second substrate portion is exposed and a third substrate portion remains covered by a remaining sacrificial layer portion. The cured layer is substantially co-planar with the remaining sacrificial layer portion. A depression is formed extending to the second substrate portion. The remaining sacrificial layer portion is utilized to define functionalized layers over different depression regions.Type: ApplicationFiled: December 19, 2022Publication date: August 17, 2023Inventors: Jeffrey S.

Publication number: 20230137978Abstract: A metal film is formed over a resin layer including a plurality of multi-depth depressions (MDP) separated by interstitial regions, each MDP including a deep portion and an adjacent shallow portion. A sacrificial layer is formed over the metal film. The sacrificial layer and metal film are sequentially dry etched to expose a resin layer surface at the shallow portion and interstitial regions. Resin layer portions are removed i) at the shallow portion to form a depression region having a surface directly adjacent to a surface at the deep portion and ii) at the interstitial regions to form new interstitial regions surrounding the deep portion and the depression region. First functionalized layer is deposited over the metal film, depression region, and new interstitial regions. The metal film is removed from the deep portion. Second functionalized layer is deposited over the surface at the deep portion. New interstitial regions are polished.Type: ApplicationFiled: May 9, 2022Publication date: May 4, 2023Inventors: Jeffrey S. Fisher, Anthony Flannery, Sahngki Hong, Brinda Kodira Cariappa, Lewis J.

Publication number: 20220382147Abstract: In an example of a method for making a flow cell, a light sensitive material is deposited over a resin layer including depressions separated by interstitial regions, wherein the depressions overlie a first resin portion having a first thickness and the interstitial regions overlie a second resin portion having a second thickness that is greater than the first thickness. A predetermined ultraviolet light dosage that is based on the first and second thicknesses is directed through the resin layer, whereby the light sensitive material overlying the depressions is exposed to ultraviolet light and the second resin portion absorbs the ultraviolet light, thereby defining an altered light sensitive material at a first predetermined region over the resin layer. The altered light sensitive material is utilized to generate a functionalized layer at the first predetermined region or at a second predetermined region over the resin layer.Type: ApplicationFiled: May 26, 2022Publication date: December 1, 2022Inventors: Brinda Kodira Cariappa, Wayne N.
