摘要: Methods are provided for manufacturing well-controlled, solid-state nanopores and arrays thereof. In one aspect, methods for manufacturing nanopores and arrays thereof exploit a physical seam. One or more etch pits are formed in a topside of a substrate and one or more trenches, which align with the one or more etch pits, are formed in a backside of the substrate. An opening is formed between the one or more etch pits and the one or more trenches. A dielectric material is then formed over the substrate to fill the opening. Contacts are then disposed on the topside and the backside of the substrate and a voltage is applied from the topside to the backside, or vice versa, through the dielectric material to form a nanopore. In another aspect, the nanopore is formed at or near the center of the opening at a seam, which is formed in the dielectric material.

摘要: A silicon substrate processing method includes forming an etching mask which has an opening portion, on a surface of a silicon substrate, forming an etching guide hole in the opening portion on the silicon substrate, and forming a through-hole which passes through the silicon substrate, by applying an etching treatment onto the silicon substrate in which the etching guide hole is formed. In the forming of the guide hole, the etching guide hole passing through the silicon substrate is formed by irradiating the opening portion with a laser beam a plurality of times, with a cooling period between each instance of irradiation with the laser beam.

摘要: A technique relates to a nanogap array. A substrate has been anisotropically etched with trenches that have tapered sidewalls. A sacrificial layer is on bottoms and the tapered sidewalls of the trenches. A filling material is formed on top of the sacrificial layer in the trenches. Nanogaps are formed where at least a portion of the sacrificial layer has been removed from the tapered sidewalls of the trenches while the sacrificial layer remains on the bottoms of the trenches. Each of the nanogaps is formed between one tapered sidewall of the substrate and a corresponding tapered sidewall of the filling material. The one tapered sidewall of the substrate opposes the corresponding tapered sidewall. A capping layer is disposed on top of the substrate and the filling material, such that the nanogaps are covered but not filled in.

摘要: A method is provided for fabricating a nanopore in a membrane. The method includes: applying an electric potential across the membrane, where value of the electric potential is selected to induce an electric field which causes a leakage current across the membrane; monitoring current flow across the membrane while the electric potential is being applied; detecting an abrupt increase in the leakage current across the membrane; and removing the electric potential across the membrane in response to detecting the abrupt increase in the leakage current.
