Abstract: Composition and methods including powder aggregates formed from tacking fine composition particles to agglomerates. The compositions provide powder aggregates where component segregation and dusting is reduced, and composition flow is improved. Embodiments can include a powder composition having an agglomeration greater than about 100 microns in diameter coated with a tacking agent; and a fine particle less than about 100 microns tacked to the agglomeration by the tacking agent. The agglomeration can be maltodextrin, flavorings, tea solids, and juice solids. The fine particles can be APM, Ace-k, sucralose, vitamins and minerals. The tacking agent can be acetylated monoglyceride, propylene glycol or a caprylic/capric triglyceride.

Abstract: A layer of photoresist provides a stress relief (or cushion) layer between a lift-off polymer layer and a barrier of multi-level lift-off structures. When multiple evaporation steps are required using the same lift-off pattern, the adhesion between organosilicon and organic film is stressed by a first blanked metal film. To prevent delamination between the lift-off polymer layer and RIE barrier photoresist is applied on top of the lift-off polymer and sandwiched between the organosilicon and organic materials. This photoresist acts as a cushion and as an adhesion promoter to reduce delamination after the metal deposition(s).
