Abstract:
본 발명은 물질의 결정구조를 이용한 패턴 형성장치를 이용함으로써, 노치(notch)가 규칙적으로 형성된 마그네틱 나노선(magnetic nanowire)을 용이하게 형성할 수 있는 레이스트랙 메모리(racetrack memory)의 제조방법에 관한 것이다. 본 발명에 따른 레이스트랙 메모리 제조방법은 격자이미지가 노치가 규칙적으로 형성되어 있는 나노선 패턴인 대상물질을 챔버에 위치시킨 후, 대상물질에 전자빔을 조사한다. 그리고 자성물질과 전자빔 레지스트가 순차적으로 적층되어 있는 기판에 대상물질을 통과한 전자빔을 조사한 후, 현상 및 식각하여 노치가 규칙적으로 형성되어 있는 마그네틱 나노선을 형성한다.
Abstract:
PURPOSE: A method for manufacturing a racetrack memory is provided to easily form a magnetic nano line by using a pattern forming device using a crystal structure of materials. CONSTITUTION: An object is a nano line pattern and is arranged on a chamber. An electron beam(500) is radiated to the object. A substrate(510) is exposed to the electron beam which passes through the object. An electron beam resister(530) exposed to the electron beam passing through the object is developed. The electron beam resister nano line pattern is formed. A magnetic nano line is formed by etching a magnetic material(520).
Abstract:
PURPOSE: An electron resist, a manufacturing method thereof are provided to simplify a manufacturing process by using an electron beam resist with conductivity and transparency. CONSTITUTION: An electron beam resist includes an HSQ(hydrogen silsesquioxane) and a carbon nanotube. An electron beam resist layer(720) is formed on the patterned target. An electron beam resist pattern(725) is formed on the electron beam resist layer. The target is patterned by using the electron beam resist pattern.
