Metal assisted chemical etching for fabricating high aspect ratio and straight silicon nanopillar arrays for sorting applications

Techniques relate to forming a sorting device. A mesh is formed on top of a substrate. Metal assisted chemical etching is performed to remove substrate material of the substrate at locations of the mesh. Pillars are formed in the substrate by removal of the substrate material. The mesh is removed to leave the pillars in a nanopillar array. The pillars in the nanopillar array are designed with a spacing to sort particles of different sizes such that the particles at or above a predetermined dimension are sorted in a first direction and the particles below the predetermined dimension are sorted in a second direction.

Controlling active fin height of FinFET device

Semiconductor devices and methods are provided to fabricate fin field-effect transistor (FinFET) devices having uniform fin height profiles. For example, uniformity of fin height profiles for FinFET devices is obtained by implementing a gate oxide removal process which is designed to prevent etching of an isolation layer (e.g., a shallow trench isolation layer) formed of an oxide material during removal of, e.g., sacrificial gate oxide layers of dummy gate structures during a replacement metal gate process.

Photosensitive resin composition and cured film prepared therefrom

Disclosed herein are a photosensitive resin composition and a cured film prepared therefrom. The photosensitive resin composition introduces a siloxane polymer containing a fluorine atom which has strong water-repellency into a composition including a common siloxane polymer and an epoxy compound, and fluorine groups may be present in the whole region of the cured film so that the water-repellency due to a fluorine component may be maintained even after removing the surface of the cured film is removed via a dry etching process. As a result, the resistance (chemical resistance) to chemicals used in a post-processing can be maximizes to provide a cured film having excellent stability.

Fin reveal forming STI regions having convex shape between fins

Integrated circuit devices include trenches in a material layer that divide the material layer into fins. With such devices, an insulator partially fills the trenches and contacts the material layer. The top surface of the insulator (e.g., the surface opposite where the insulator contacts the material layer) has a convex dome shape between at least two of the fins. The dome shape has a first thickness from (from the bottom of the trench) where the insulator contacts the fins, and a second thickness that is greater than the first thickness where the insulator is between the fins. Further, there is a maximum thickness difference between the first and second thicknesses at the midpoint between the fins (e.g., the highest point of the dome shape is at the midpoint between the fins). Also, the top surface of the first insulator has concave divots where the first insulator contacts the fins.
