摘要:
A method of fabricating an integrated circuit device includes forming first and second gate patterns on surfaces of a semiconductor substrate in PMOS and NMOS regions, respectively, of the substrate. P-type source/drain regions are epitaxially grown on opposite sides of the first gate pattern in the PMOS region to exert compressive stress on a first channel region therebetween adjacent the first gate pattern. N-type source/drain regions are epitaxially grown on opposite sides of the second gate pattern in the NMOS region to exert tensile stress on a second channel region therebetween adjacent the second gate pattern. Related devices are also discussed.

Provided is a device for resizing a JPEG image having a nonstandard size at a predetermined ratio to output the resized image on a display unit without distortion in a mobile communication terminal. A method for processing a JPEG image in a mobile communication terminal comprises extracting image sizes (X, Y) from JPEG data of a JPEG file stored in an image data storing unit, comparing display area sizes (dx, dy) of the display unit with the image sizes (X, Y), and resizing the image sizes (X, Y) while maintaining the ratio of width:length in consideration of the display area sizes (dx, dy) to output the resized image to the display unit.

A method of manufacturing a bipolar device including pre-treatment using germane gas and a bipolar device manufactured by the same. The method includes forming a single crystalline silicon layer for a base region on a collector region; and forming a polysilicon layer for an emitter region thereon. Here, before the polysilicon layer is formed, the single crystalline silicon layer is pre-treated using germane gas. Thus, an oxide layer is removed from the single crystalline silicon layer, and a germanium layer is formed on the single crystalline silicon layer, thus preventing Si-rearrangement.

In a metal-oxide semiconductor (MOS) transistor with an elevated source/drain structure and in a method of fabricating the MOS transistor with the elevated source/drain structure using a selective epitaxy growth (SEG) process, a source/drain extension junction is formed after an epi-layer is formed, thereby preventing degradation of the source/drain junction region. In addition, the source/drain extension junction is partially overlapped by a lower portion of the gate layer, since two gate spacers are formed and two elevated source/drain layers are formed in accordance with the SEG process. This mitigates the short channel effect and reduces sheet resistance in the source/drain layers and the gate layer.

A method for manufacturing a high-transmittance optical filter for image display devices, which may include the steps of coating a photocatalytic compound on a transparent substrate to form a photocatalytic film, selectively exposing the photocatalytic film to light and growing a metal crystal thereon by plating to form a metal pattern, and selectively etching and removing the photocatalytic compound remaining on the transparent substrate using a buffered oxide etchant (BOE). According to the method, a high-transmittance, high-resolution and low-resistivity optical filter can be manufactured in a simple manner at low costs.

A multi-layered structure of a semiconductor device includes a substrate, and a heteroepitaxial layer having a low dislocation defect density on the substrate. The heteroepitaxial layer consists of a main epitaxial layer and at least one intermediate epitaxial layer sandwished in the main epitaxial layer. At their interface, the heteroepitaxial layer, i.e., the bottom portion of the main epitaxial layer, and the substrate have different lattice constants. Also, the intermediate epitaxial layer has a different lattice constant from that of the portions of the main epitaxial layer contiguous to the intermediate epitaxial layer. The intermediate epitaxial layer also has a thickness smaller than the net thickness of the main epitaxial layer such that the intermediate epitaxial layer absorbs the strain in the heteroepitaxial layer. Thus, it is possible to obtain a multi-layered structure comprising an epitaxial layer that is relatively thin and has a low dislocation defect density.
