Publication number: 20130137270Abstract: A method for forming contact holes includes following steps. A substrate including a dense region and an isolation region is provided. A material layer is formed on the substrate. Sacrificed patterns are formed on the material layer in the dense region, wherein there is a first opening between the two adjacent sacrificed patterns. A spacer is formed on each of two sides of each of the sacrificed patterns, wherein the spacers are separated from each other. The sacrificed patterns are removed to form a second opening between two adjacent spacers. A planar layer is formed to fill up the second openings. A first slit is formed in the planar layer, wherein the first slit exposes a portion of the material layer under the second openings. The portion of the material layer exposed by the first slit is removed to form third openings in the material layer.Type: ApplicationFiled: February 1, 2012Publication date: May 30, 2013Applicant: POWERCHIP TECHNOLOGY CORPORATIONInventors: Meng-Feng Tsai, Yi-Shiang Chang, Chia-Chi Lin, I-Hsin Chen, Chia-Ming Wu

Publication number: 20130089986Abstract: A method of forming patterns of a semiconductor device may include forming a photoresist layer that includes a photo acid generator (PAG) and a photo base generator (PBG), generating an acid from the PAG in a first exposed portion of the photoresist layer by first-exposing the photoresist layer, and generating a base from the PBG in a second exposed portion of the photoresist layer by second-exposing a part of the first exposed portion and neutralizing the acid. The method may also include baking the photoresist layer after the first and second-exposing and deblocking the photoresist layer of the first exposed portion in which the acid is generated to form a deblocked photoresist layer, and forming a photoresist pattern by removing the deblocked photoresist layer by using a developer.Type: ApplicationFiled: September 10, 2012Publication date: April 11, 2013Inventors: Jeong-ju PARK, Kyoung-mi KIM, Min-jung KIM, Dong-jun LEE, Boo-deuk KIM
