Abstract:
포토레지스트 패턴의 형성방법이 개시된다. 대상물 상에 상기 대상물의 소정부위를 노출시키는 예비 포토레지스트 패턴을 형성한다. 상기 예비 포토레지스트 패턴에 린스액을 제공하여 상기 예비 포토레지스트 패턴의 표면을 화학적으로 용융시켜 상기 소정 부위보다 작은 부위를 노출시키는 포토레지스트 패턴을 형성한다. 따라서 패턴의 형태나 소밀에 영향을 받지 않아 패턴 의존성을 최소화 하면서 라인 앤 스페이스(line-&-space), 콘택홀 등의 임계치수를 효과적으로 제어할 수 있으며 또한, 노광된 빛의 상호 간섭현상에 의해서 발생하는 패턴 세화현상(pattern thinning)을 광근접성보정(optical proximity correction)등과 같은 추가적인 보정 기술이 없이도 용이하게 보정할 수 있다.
Abstract:
Disclosed is a method for manufacturing a semiconductor device by employing a dual damascene process. After a first insulation film including a conductive pattern is formed on a substrate, at least one etch stop film and at least one insulation film are alternatively formed on the first insulation film. A via hole for a contact or a trench for a metal wiring is formed through the insulation film, and then the via hole or the trench is filled with a filling film including a water-soluble polymer. After a photoresist film is coated on the filling film, the photoresist film is patterned to form a photoresist pattern and to remove the filling film. The DOF and processing margin of the photolithography process for forming the photoresist pattern can be improved because the photoresist film can have greatly reduced thickness due to the filling film.

PURPOSE: A method for planarizing a semiconductor device to reduce a step of the surface of a substrate and improve planarization by interposing an interlayer dielectric between upper and lower photoresist layers. CONSTITUTION: A planarization pattern of the first photoresist layer is formed in a predetermined region of a stepped upper surface of a substrate. An interlayer dielectric is formed on the upper surface of the pattern of the first photoresist layer. The second photoresist layer for planarization is formed on the upper surface of the interlayer dielectric. The pattern of the first photoresist layer is flowed at a temperature of 160 deg.C.

PURPOSE: A method for forming a pattern of a semiconductor device and a photo mask used for the same are provided to be capable of reducing proximity effect. CONSTITUTION: A semiconductor device is defined with the first and second region. At this time, a plurality of first patterns(12) are regularly spaced apart from each other as much as the first interval at the first region. At the time, a plurality of second patterns(14) are regularly spaced apart from each other as much as the second interval. Preferably, the second interval is larger than the first interval. A photo mask(30) is installed at the upper portion of the semiconductor device for forming the first and second patterns. The photo mask includes the first and second mask patterns(22,24) corresponding to the first and second patterns of the semiconductor device, respectively. The second mask pattern has a fine space(26) at the center portion for minimizing proximity effect.
Abstract:
PURPOSE: A method for fabricating a photoresist pattern and a blanket exposure apparatus is provided to uniformly form a photoresist layer only on the sidewall of the opening of the photoresist pattern by exposing the front surface of the photoresist pattern including the photoresist layer. CONSTITUTION: The first photoresist material is formed on a substrate(50) to form the first photoresist layer. The first photoresist layer is selectively removed to form the first opening of the first line width. The first photoresist pattern is formed in which the substrate is exposed. The second photoresist material is continuously formed on the sidewall and the bottom of the first photoresist pattern and the first opening to form the second photoresist layer. An exposure process is performed on the front surface of the second photoresist layer. The exposed second photoresist layer is eliminated so that the second photoresist layer exists only on the sidewall of the first photoresist pattern and the second photoresist pattern(60b) including the second opening of the second line width is formed.

PURPOSE: A method for forming a capacitor of a semiconductor device using a damascene process is provided to improve capacitance of a capacitor by making a dielectric layer remain on a side wall of a contact hole. CONSTITUTION: The third photoresist patterns are removed. The third poly silicone layer is formed on a front surface including the second contact hole. The third poly silicone layer is selectively etched and removed so that the second interlayer dielectric(28) is exposed on a surface thereof by using a chemical mechanical polishing process. A storage electrode(32) is formed so as for the third poly silicon layer to remain on a side wall of the contact hole and the second contact hole. An interlayer dielectric having an opening part is formed on a semiconductor substrate. A photoresist pattern is formed on the interlayer dielectric by using a damascene process. When the interlayer dielectric is partially removed by using the photoresist pattern as a mask, a side wall of the opening part remains as it is. A conductive layer is formed on the opening part and a side wall of the opening part.
