Title: Method for automatically controlling density of nitric oxide in process for cleaning stainless steel with nitric acid
Inventor: CHOI SANG GYO
IPC: C23G1/02
Filed: 1998-12-24
Abstract: PURPOSE: A method is provided to control amount of nitric oxide by directly injecting peroxide to a stainless steel or adding peroxide to acid cleaning liquid according to the detected density of nitric oxide. CONSTITUTION: A nitric oxide analyzer(8) analyzes density of nitric oxide generated when a stainless steel is cleaned with acid. According to the density, peroxide is input to an acid cleansing tank while adjusting flux of peroxide. Flux of peroxide is adjusted by turning on and off a peroxide inputting pump(2) and peroxide is injected to a stainless steel in the acid cleansing tank through a nozzle placed at the interval of 30cm.

Title: Mos transistor having metal silicide layer and fabrication method thereof
Inventor: KIM U SIK
IPC: H01L29/78
Filed: 1998-12-29
Abstract: PURPOSE: A MOS transistor having a metal silicide layer and a fabricating method thereof are provided to prevent junction leakage current and to reduce gate contact resistance. CONSTITUTION: To form a MOS transistor, an active region is defined between field oxide layers(104) formed on a semiconductor substrate(102). In the active region, a gate oxide layer(106) and a gate(108) are centrally formed on the substrate(102), and source/drain regions(110,114) are peripherally formed in the substrate(102) around the gate(108). In addition, a first insulating layer(111S) and a spacer(112S) are formed enclosing the gate(108) but exposing upper portions of the gate(108). Moreover, a metal silicide layer(116) is formed covering the source/drain regions(110,114) and capping the upper portions of the gate(108). The silicide layer(116) on the gate(108) is somewhat extended to the sides of the gate(108), so that contact area between the silicide layer(116) and the gate(108) is increased and thereby gate contact resistance is reduced.

Abstract: PURPOSE: A method for assigning the frame offsets and links of a base station is provided to improve the performance of a mobile communication system by allocating resources so that soft hand-off can be generated in frame offset allocation. CONSTITUTION: If a hand-off call channel allocation request is received from a base station controller, the base station stores information transmitted from the base station controller in an internal memory. The base station searches the number of the current users by links. The base station discriminates the status of links. If an abnormal link exists, the base station excepts the abnormal link and confirms whether normal links exists. In case that all links are abnormal, the base station informs the base station controller that hand-off channel allocation has been failed. If all links are normal, the base station arrays links in sequence that the number of users is small.
