Patent
Nonvolatile semiconductor memory device and method for manufacturing same
Shigeki Hattori,Reika Ichihara,Masaya Terai,Hideyuki Nishizawa,Tsukasa Tada,Koji Asakawa,Hiroyuki Fuke,Satoshi Mikoshiba,Yoshiaki Fukuzumi,Hideaki Aochi +9 more
TL;DR: In this article, a nonvolatile semiconductor memory device, including a stacked structural unit including a plurality of insulating films alternately stacked with a multiplicity of electrode films in a first direction, is described.
Patent
Method for manufacturing porous structure and method for forming pattern
TL;DR: In this article, the ratio between N/(Nc−No) values of monomer units constituting respective polymer chains is 1.4 or more, where N represents total number of atoms in the monomer unit, Nc represents the number of carbon atoms in monomeres unit, No represents the amount of oxygen atoms in a monomere unit.
Patent
Light-emitting device and method for manufacturing the same
TL;DR: In this article, a nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved by selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface.
Journal ArticleDOI
Nanopatterning with Microdomains of Block Copolymers using Reactive-Ion Etching Selectivity
Koji Asakawa,Toshiro Hiraoka +1 more
TL;DR: In this article, the authors attempted to transfer the microdomains onto substrates by only using the reactive-ion etching (RIE) method, which is widely used in semiconductor manufacturing processes.
Journal ArticleDOI
Aluminum nanowire polarizing grids: Fabrication and analysis
Vincent Pelletier,Koji Asakawa,Koji Asakawa,Mingshaw Wu,Douglas H. Adamson,Richard A. Register,Paul Chaikin,Paul Chaikin +7 more
TL;DR: In this article, a metal wire grid with 33nm periodicity was used as a transmission polarizer for visible and near-ultraviolet (ultraviolet) lights, which achieved a near 50% efficiency in the visible.
