摘要:
A semiconductor device having multi-gate insulating layers and methods of fabricating the same are provided. The semiconductor device includes an isolation region disposed at a predetermined region of a semiconductor substrate. The isolation region defines at least one first active region and at least one second active region. The first active region is covered with a first gate insulating layer, and the second active region is covered with a second gate insulating layer which is thinner than the first gate insulating layer. Preferably, the top surface of the first gate insulating layer has the same height as the that of the second gate insulating layer. The isolation region is filled with an isolation layer which preferably covers the entire sidewalls of the first and second gate insulating layers. A typical method includes the step of selectively forming a first gate insulating layer at a predetermined region of a semiconductor substrate. A second gate insulating layer which is thinner than the first insulating layer is selectively formed at the surface of the semiconductor substrate adjacent to the first gate insulating layer. Preferably, the bottom surface of the first gate insulating layer is lower than that of the second gate insulating layer. The first and second gate insulating layers are covered with a conductive layer. The conductive layer, the first and second gate insulating layers, and the substrate are etched to form an isolation region, for example, a trench region, defining a first active region under the first gate insulating layer and a second active region under the second gate insulating. An isolation layer is formed in the trench region. The isolation layer preferably covers the entire sidewalls of the first and second gate insulating layers.

Methods of forming a semiconductor device may include providing a feature layer having a first region and a second region. The methods may also include forming a dual mask layer on the feature layer. The methods may further include forming a variable mask layer on the dual mask layer. The methods may additionally include forming a first structure on the feature layer in the first region and a second structure on the feature layer in the second region by patterning the variable mask layer and the dual mask layer. The methods may also include forming a first spacer on a sidewall of the first structure and a second spacer on a sidewall of the second structure. The methods may further include removing the first structure while maintaining at least a portion of the second structure.

A flash memory management method is provided. According to the method, when a request to write the predetermined data to a page to which data has been written is made, the predetermined data is written to a log block corresponding to a data block containing the page. When a request to write the predetermined data to the page again is received, the predetermined data is written to an empty free page in the log block. Even if the same page is requested to be continuously written to, the management method allows this to be processed in one log block, thereby improving the effectiveness in the use of flash memory resources.

Disclosed is a wood flooring containing laminated wood and high-density fiberboard using a symmetric structure and a process for manufacturing the same. The wood flooring includes a high-density fiberboard core layer and an upper laminated wood layer and lower laminated wood or veneer layer symmetrically stacked about the high-density fiberboard core layer to achieve a stable structure, and the lower laminated wood or veneer layer has a density of 100±30% of that of the upper laminated wood layer to keep the balance therebetween. With this configuration it is possible to completely eliminate deformation problems caused by variation of environmental conditions such as temperature, humidity, etc., and to impart the natural texture of raw lumber and high durability to the flooring surface.

A method and apparatus for controlling an image in a wireless terminal transmitting/receiving a facial expression photograph in a message transmission/reception mode and a video call mode are provided. If a facial expression photograph attachment option is selected in a message transmission mode, facial expression types are displayed. A facial expression of a photograph to be transmitted is changed to a facial expression selected from the facial expression types, and the selected facial expression is attached as a facial expression photograph. A message attached to the facial expression photograph is then transmitted.
