摘要:
A method of manufacturing a mask includes dividing an upper surface of a template having a design pattern into a plurality of regions, the template being arranged over a polymer layer on a mask substrate, correcting a distorted region among the regions, pressing the polymer layer with the template to form a mask pattern corresponding to the design pattern on the polymer layer; and curing the mask pattern.

A method of measuring an overlay of an object is provided. In the method, first information of a first structure may be obtained. A preliminary structure may be formed on the first structure. Second information of the preliminary structure may be obtained. The first information and the second information may be processed to obtain virtual information of a second structure that would be formed on the first structure if a process is performed on the preliminary structure. A virtual overlay between the first structure and the second structure may be measured using the virtual information.

The energy distribution of exposure light directed passing through the slit of an exposure apparatus is determined. A photoresist layer on a substrate is exposed over a plurality of shots while changing the intensity of the exposure light for each shot. Then the photoresist layer is developed to form a sample photoresist layer. An image of the developed sample photoresist layer is analyzed for color intensity. Values of the color intensity across a selected one of the shots are correlated with values of the intensity of the exposure light to produce an energy distribution of the exposure light along the length of the slit. The energy distribution is used to change the slit so that a more desirable energy distribution may be realized when the slit is used in a process of manufacturing a semiconductor device.

A liquid crystal display (LCD) module includes a bottom case; a reflector on the bottom case; a plurality of lamps on the reflector; a driving voltage supply portion supplying driving voltages to the lamps and coupled with the bottom case using a screw; a side supporter crossing and covering one end portions of the lamps and including a protrusion facing a head of the screw, wherein a distance between the protrusion and the screw is less than a height of the screw; a plurality of optical sheets on the side supporter; a liquid crystal panel on the optical sheets; a main supporter surrounding the optical sheets and the liquid crystal panel; and a top case covering a peripheral region of the liquid crystal panel.
摘要:
A method of reworking a semiconductor substrate and a method of forming a pattern of semiconductor device using the same without damage to an organic anti-reflective coating (ARC) is provided. The method of reworking a semiconductor substrate includes forming a photoresist pattern on a substrate having the organic ARC formed thereon. An entire surface of the substrate having the photoresist pattern formed thereon may be exposed when a defect is present in the photoresist pattern. The entire-surface-exposed photoresist pattern may be removed by performing a developing process without damage to the organic ARC.

Mask sets are provided which may be used to define a first pattern region that has a first pitch pattern and a second pattern region that has a second pitch pattern during the fabrication of a semiconductor device. These mask sets may include a first mask that has a first exposure region in which a first halftone pattern defines the first pattern region and a first screen region in which a first shield layer covers the second pattern region. These mask sets may further include a second mask that has a second exposure region in which a second halftone pattern defines the second pattern region and a second screen region in which a second shield layer covers the first pattern region. The second shield layer also extends from the second screen region to cover a portion of the second halftone pattern.
