Abstract: A method of forming a semiconductor structure includes forming a substrate, forming an anchor layer, and forming one or more self-aligned nanotip pillar pairs disposed vertically between the substrate and the anchor layer. A given one of the nanotip pillar pairs comprises a bottom nanotip pillar and a top nanotip pillar, the bottom nanotip pillar comprising a base portion disposed on a top surface of the substrate and the top nanotip pillar comprising a base portion disposed in the anchor layer. The bottom nanotip pillar and the top nanotip pillar comprise sidewalls that taper to points as distance from the respective base portions increases.

Abstract: A semiconductor device is proposed. The semiconductor device comprises a membrane structure having an opening. Furthermore, the semiconductor device comprises a first backplate structure, which is arranged on a first side of the membrane structure, and a second backplate structure, which is arranged on a second side of the membrane structure. The semiconductor device furthermore comprises a vertical connection structure, which connects the first backplate structure to the second backplate structure. In this case, the vertical connection structure extends through the opening.

Abstract: A three-dimensional micro-structure has a plurality of adjacent micro-columns which are arranged at a distance from each other and essentially parallel in relation to the respective longitudinal extension. The micro-columns are made of at least one micro-column material having respectively an aspect ratio in the region of 20-1000 and respectively a micro-column diameter in the region of 0.1 μm-200 μm. A micro-column intermediate chamber is arranged between adjacent micro-columns having a micro-column distance selected from between the adjacent micro-columns in the region of 1 μm-100 μm. According to a method for producing the three-dimensional micro-structures: a) a template is provided with template material, b) the micro-column material is arranged in the column-like cavities, and c) the template is at least partially removed.

Abstract: A technique related to sorting entities is provided. An inlet is configured to receive a fluid, and an outlet is configured to exit the fluid. A nanopillar array, connected to the inlet and the outlet, is configured to allow the fluid to flow from the inlet to the outlet. The nanopillar array includes nanopillars arranged to separate entities by size. The nanopillars are arranged to have a gap separating one nanopillar from another nanopillar. The gap is constructed to be in a nanoscale range.
