    • A method of fabricating a semiconductor device forms a shallow source/drain region after a deep source/drain region. First, a gate insulating layer including a gate pattern and a gate electrode are formed on a semiconductor substrate. A buffer insulating layer, a first insulating layer, and a second insulating layer are then sequentially formed on the entire surface of the gate pattern and the semiconductor substrate. A first spacer is formed on the first insulating layer at both sidewalls of the gate pattern by etching the second insulating layer. A deep source/drain region is then formed on the semiconductor substrate as aligned by the first spacer. The first spacer is removed. Next, an offset spacer is formed at both sidewalls of the gate pattern by etching the first insulating layer. Finally, a shallow source/drain region is formed on the semiconductor substrate adjacent to the deep source/drain region as aligned by the offset spacer.
    • 半导体器件的制造方法在深源极/漏极区域之后形成浅的源极/漏极区域。 首先,在半导体基板上形成包括栅极图案和栅电极的栅极绝缘层。 然后在栅极图案和半导体衬底的整个表面上依次形成缓冲绝缘层,第一绝缘层和第二绝缘层。 通过蚀刻第二绝缘层,在栅极图案的两个侧壁的第一绝缘层上形成第一间隔物。 然后在第一间隔物对准的半导体衬底上形成深源/漏区。 第一个垫片被去除。 接下来,通过蚀刻第一绝缘层在栅极图案的两个侧壁处形成偏移间隔物。 最后,在与偏移间隔物对齐的深源/漏区附近的半导体衬底上形成浅源极/漏极区。

    • In a trench isolation method, a semiconductor substrate having an N-MOS region and a P-MOS region is prepared. A first mask pattern exposing an N-MOS field region is formed on the N-MOS region, and a second mask pattern exposing a P-MOS field region is formed on the P-MOS region. A first photoresist pattern is formed to cover the P-MOS region and expose the N-MOS region. First impurity ions are implanted into the N-MOS region, using the first mask pattern and the first photoresist pattern as ion implantation masks, thereby forming a first impurity layer in the N-MOS field region. In this case, a portion of the first impurity layer is formed to extend below the first mask pattern. The first photoresist pattern is removed. The semiconductor substrate is etched using the first and second mask patterns as etch masks, thereby forming trenches in the N-MOS field region and the P-MOS field region and concurrently, forming a first impurity pattern of the first impurity layer remaining below the first mask pattern. A trench isolation layer filling the trenches is then formed.

    • The present invention relates to a scheduling apparatus and a method thereof in an HPi system. A scheduling algorithm is applied appropriate to a characteristic of each multimedia service (e.g., real-time service, non real-time service, best-effort service, etc.) and a transmission order of the IP packets transmitted from a network is determined such that a transmit wait queue is generated. Radio resource allocation is performed in accordance with the order of the data items queued in the transmit wait queue, the size of transmittable data is determined such that a PDU is generated. In addition, frame data formed of bursts of PDUs is generated and transmitted to a physical layer. Therefore, a scheduling algorithm can be applied appropriate to characteristics of each multimedia service. In addition, packet scheduling is performed in two steps in order to schedule traffic corresponding to radio frames such that packets can be efficiently processed.

    • The present invention relates to a method for searching and releasing an abnormal subscriber station in a wireless portable Internet system, and an apparatus using the same. The apparatus searches for an abnormal group including abnormal subscriber stations based on a ranging code provided in a periodic ranging process, and searches for an abnormal subscriber station by transmitting a connection maintenance message to subscriber stations included in the abnormal group so as to check an operation status of the respective subscriber stations. In addition, the apparatus releases a connection of an abnormal subscriber station. Therefore, waste of radio resources allocated to the abnormal subscriber station can be prevented, thereby achieving efficient resource management. Further, a secondary search process is performed only for subscriber stations included in an abnormal group, thereby preventing a system load from occurring when searching for an abnormal subscriber station.
