Abstract: A method for forming a semiconductor device is provided to suppress generation of particles since an etch mask is formed by etching a coating layer using a spin coating. A method for forming a semiconductor device includes the steps of: forming a coating film(120) on a substrate(110); forming a first photoresist film(130) and a second photoresist film(140) on the coating film; forming a coating film pattern, a first photoresist pattern, and a second photoresist pattern by patterning the coating film, the first photoresist film, and the second photoresist film; and etching the exposed substrate.

Abstract: A method for forming a photoresist pattern is provided to coat a subsequentially formed layer without causing defects by performing a cleaning process for converting the surface of a hard mask layer including an SOG(spin on glass) material into a hydrophilic material. A preliminary hard mask layer including carbon as an SOG material can be formed on a substrate. A hard mask layer including a SOG material is formed on the resultant structure(S100). A cleaning process for surface treatment is performed to make the surface of the hard mask layer have a hydrophilic property(S110). An ARC(anti-reflective coating) is formed on the hard mask layer(S120). A photoresist layer is formed on the ARC(S130). The photoresist layer is patterned to form a photoresist pattern(S140).

Abstract: A method for forming a hard mask is provided to obtain a photoresist pattern with finer line width while reducing standing wave formation in photoresist by forming the photoresist pattern on a spin-on carbon layer that has low reflectivity to ArF laser. A method for forming a hard mask comprises the steps of: forming a first layer(21) above a substrate(1), wherein the first layer is a spin-on carbon that is an amorphous carbon layer; forming a photoresist pattern(32) above the first layer; forming a second layer(41) having a reflectivity higher than that of the first layer, wherein the second layer is a spin-on glass layer that is a silicon oxide layer; removing the second layer until the photoresist pattern is exposed; removing the photoresist pattern to form a second pattern; and etching the first layer using the second pattern as an etching mask, to form a first pattern.
