Title: Method for manufacturing a flash memory cell
Inventor: PARK SU YEONG
IPC: H01L21/336
Filed: 2000-08-01
Abstract: PURPOSE: A method for fabricating a flash memory cell is provided to prevent a poor step coverage of layers disposed over a floating gate. CONSTITUTION: A tunnel oxide layer(13) and the first polysilicon layer(14) are sequentially formed on a semiconductor substrate(11) having an isolation layer(12). The first polysilicon layer(14) and the tunnel oxide layer(13) are then patterned to form the floating gate. Next, a spacer(16) is formed on a sidewall of the floating gate. Thereafter, a dielectric layer(17), the second polysilicon layer(18), a tungsten silicide layer(19) and a hard mask layer(20) are formed in sequence on a resultant entire structure and then patterned to form a control gate. Since the spacer(16) serves to reduce the surface morphology of the floating gate, a poor step coverage of layers forming the control gate is improved. Next, impurity ions are implanted into the substrate(11) to form junction regions.

Title: Method for office line recovery in switching system
Inventor: LEE U GYEONG
IPC: H04M3/22
Filed: 2000-09-29
Abstract: PURPOSE: A method of recovering an office line of an exchange is provided to recover an office line when a congestion tone is detected while monitoring signals incoming from the busy office line, so that other office line subscriber can re-occupy the corresponding office line by quickly recovering the office line. CONSTITUTION: A standard pattern of a congestion tone is defined while initializing a system(S10). If a corresponding office line becomes busy due to a call connect request from an office line subscriber(S12), a congestion tone detector confirms signals incoming from the office line at regular intervals, and decides whether the incoming signals are the same as a frequency of a congestion tone(S14,S16). If so, the detector sets a congestion tone detection bit to '1' to shift from the right to the left in a temporary storage. If the signals are not the same as the frequency, the detector sets the bit to '0' to shift from the right to the left in the temporary storage(S18,S20). The detector decides whether the most significant bit is set to '1' while storing congestion tone detection data in the temporary storage(S22). If so, the detector assumes correlations and features between the congestion detection data and the standard pattern, to decide whether the congestion tone detection data is similar to the standard pattern(S24,S26). If so, the detector considers a signal incoming from the office line as a congestion tone, and reports the signal to a call processor(S28). The call processor requests an office line manager to recover the corresponding office line(S30). The office line manager recovers the office line(S32).
