Latest Patents
Aurélien Sarrazin holds a patent for a "Method for selective etching of a block copolymer." This method involves etching a layer of assembled block copolymer that includes first and second polymer phases. The etching process consists of two steps: the first step utilizes a plasma formed from carbon monoxide or a gas mixture that includes a fluorocarbon gas and a depolymerizing gas. This step partially etches the first polymer phase while depositing a carbon layer on the second polymer phase. The second step employs a different plasma formed from a gas mixture that includes a depolymerizing gas and a gas selected from carbon oxides and fluorocarbon gases. This step effectively etches both the first polymer phase and the carbon layer on the second polymer phase.
