摘要： A photoresist layer comprising an optically active component is provided, so that after an incident linearly polarized light penetrates the photoresist layer, the intensity ratio of an S wave polarization and a P wave polarization divided from the linearly polarized light is effectively 1:1 so improving astigmatism.

摘要： A photoresist with adjustable polarized light response and a photolithography process using the photoresist. The photoresist and the photolithography process are suitable for use in an exposure optical system with a high numerical aperture. The photoresist includes a photosensitive polymer that can absorb the exposure light source to generate an optical reaction. The photosensitive polymer can also be oriented along a direction of an electric field or a magnetic field. The response for the photosensitive upon a polarized light is determined by an angle between the predetermined direction and the polarized light. In addition, the photolithography process adjusts the orientation of the photosensitive polymer, so that the P-polarized light has a weaker response than that of the S-polarized light to compensate for the larger transmission coefficient of the P-polarized light with a high numerical aperture, so as to prevent the photoresist pattern deformation.

摘要： Semiconductor devices, having dual silicides, include a first fin, having N-type impurities, and a second fin, having P-type impurities, on a substrate. A first gate electrode and a first source/drain area are on the first fin. A second gate electrode and a second source/drain area are on the second fin. An etch stop layer is on the first source/drain area and the second source/drain area. An insulating layer is on the etch stop layer. A first plug connected to the first source/drain area and a second plug connected to the second source/drain area are formed through the insulating layer and the etch stop layer. A first metal silicide layer is in the first source/drain area. A second metal silicide layer having a material different from the first metal silicide layer and having a thickness smaller than the first metal silicide layer is in the second source/drain area.
