Abstract: An etch method includes etching a masked substrate to form a recess with a first sidewall in the substrate. A thin surface layer of the substrate on the first sidewall is then converted into a passivation layer. The masked substrate is etched again to deepen the recess in the substrate. A surface layer of the substrate on the second sidewall of the recess is then converted into a passivation layer. In one embodiment, upon removal of the passivation layers from both sidewalls, the first and second sidewalls of the high aspect ratio recess are aligned to within 10 ? of each other to provide a high aspect ratio recess having a vertical profile.

Abstract: A divided Media Access Control (MAC) protocol structure, a data transmission and reception method, and a handover method and system using the structure in a wireless communication system for efficiently managing session information in handover of an MSS (Mobile Subscriber Station). In the MAC protocol structure, a MAC is divided into a MAC-high layer and a MAC-low layer. The MAC-high layer performs session information-related functions and the MAC-low layer performs functions sensitive to a time delay in relation to handover of an MSS. In the handover method, when an MSS in the wireless communication system performs handover between Access Points (APs), session information is managed at a fixed position by an Access Point Controller (APC) including an MAC-high layer or a serving AP. Therefore, the system load can be reduced and communication quality can be improved.

Upon receipt of the location update message, the centralized database updates dormant state information for the mobile station to connect the target BSC to the source BSC. The centralized database transmits a location update result message indicating complete update of the dormant state information to the target BSC.
