Abstract: Disclosed herein are methods for forming wall oxide films in flash memory devices and methods for forming isolation films. After trenches are formed in the substrate, an ISSG (In-Situ Steam Generation) oxidization process is performed to form wall oxide films on sidewalls of the trenches. This process prohibits formation of facets at the top and bottom edge portions of the trenches. Thus, the top edges of the trenches are rounded. Furthermore, the ISSG oxidization process is performed at a low temperature for a relatively short time. Therefore, thermal stress due to carrying out an oxidization process for a long time is reduced and a dislocation phenomenon is thus prevented from occurring.

Abstract: Disclosed is a method of manufacturing the semiconductor devices. The method comprising the steps of forming a gate electrode on a semiconductor substrate, depositing an oxide film for a spacer on the gate electrode, implementing an anisotropic dry etch process for the oxide film for the spacer to form spacers at the sidewalls of the gate electrode, and implementing a rapid thermal annealing process for the spacers under an oxygen atmosphere in order to segregate hydrogen contained within the spacers toward the surface. Therefore, hydrogen contained within the spacer oxide film is not diffused into the tunnel oxide film and the film quality of the tunnel oxide film is thus improved. As a result, program or erase operation characteristics of the flash memory device and a retention characteristic of the flash memory device could be improved.

Abstract: Disclosed is a method of manufacturing a semiconductor device. A gate is formed on a given region of a semiconductor substrate. Spacers are then formed using DCS-HTO or TEOS. Hydrogen remaining within the spacers is removed by a RTA process under nitrogen atmosphere and nitride films are formed on the spacers at the same time. In case of a flash memory device, a retention characteristic can be improved. A process of forming the nitride film additionally required in a subsequent contact hole formation process may be omitted. The sheet resistance of the gate could be improved by promoting growth of a crystal grain of a tungsten silicide film constituting a control gate.

Abstract: An MPEG-4 encoder utilizing an H.263 multimedia chip. The MPEG-4 encoder includes a DC (Direct Current) predictor for predicting a DC component of the image frame encoded by an H.263 standard upon receiving a prescribed MPEG-4 quantization value, and an MPEG-4 reconstruction image memory for converting the H.263 reconstruction image into an MPEG-4 reconstruction image, and storing the MPEG-4 reconstruction image. The MPEG-4 encoder removes spatial redundancy from source image data entered in frame units using a prescribed H.263 quantization value, predicts a DC component of an image frame having no spatial redundancy using a prescribed MPEG-4 quantization value, performs a VLC (Variable Length Coding) process on the image frame using the predicted DC component, and outputs the VLC-processed image frame in the form of an MPEG-4 bit stream. The MPEG-4 encoder reconstructs the image frame having no spatial redundancy, stores the reconstructed image frame, converts the reconstructed image frame into an MPEG-4 frame, stores the MPEG-4 frame, compares the stored image frame with a newly-entered next frame, and removes temporal redundancy according to a result of the comparison.
