Abstract: Disclosed herein is a method for forming an isolation film of a semiconductor memory device. According to the disclosure, in a pre-treatment cleaning process performed before a tunnel oxide film is formed, a SC-1 cleaning process is performed at a temperature ranging from 60° C. to 70° C. Therefore, oxide films in a cell region and a peripheral region are recessed even in the SC-1 cleaning process as well as a DHF cleaning process. A DHF cleaning time can be thus reduced. Accordingly, the method can minimize loss of a silicon substrate by DHF and can thus control the depth of a moat.

Abstract: The present invention relates to a porcine uroplakin II gene promoter, an expression vector containing the promoter, and a method for producing useful proteins using the vector. The promoter of the present invention promotes the bladder-specific expression of a target protein at high efficiency. An animal, which was transformed using the inventive promoter so as to express the target protein, secretes the target protein in its urine at high concentration, and the protein thus produced shows a superior physiological activity to that of the same kind of the existing protein. As a result, the inventive promoter, the expression vector and transgenic animal using the promoter, can be advantageously used in the production field of useful proteins that are medicinally valuable.

Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance. <IMAGE>
