Abstract: In one example, a flow cell includes a base support and a protrusion over the base support, where the protrusion is a different material than the base support. The flow cell further includes a first functionalized layer over a first portion of the protrusion, a second functionalized layer over a second portion of the protrusion, and first and second primer sets respectively attached to the first and second functionalized layers.

Abstract: 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.

Abstract: Registration of a patterned flow cell may utilize fiducials comprising sets or groupings of features (e.g., sites, sample wells, nanowells) having known locations and in which the placement of the features is not in accordance with a periodic pattern or is otherwise distinguishable from the periodic pattern of sites present in non-fiducial regions of the flow cell substrate. In certain embodiments the positioning of the sites that are part of the fiducial represent a break or discontinuity in the periodic pattern of sites that are otherwise present on the surface of a patterned flow cell.

Abstract: 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.

Abstract: An example flow cell includes a multi-layer stack including a transparent base support; a patterned sacrificial layer over the transparent base support; and a transparent layer over the patterned sacrificial layer. The flow cell further includes first and second functionalized layers over different portions of the transparent layer, wherein at least one of the first and second functionalized layers aligns with a pattern of the patterned sacrificial layer; and first and second primer sets respectively attached to the first and second functionalized layer.
