In a method of fabricating local interconnection, a selective epitaxial growth seed layer pattern is formed on a region of a semiconductor substrate where a local interconnection is to be formed. A selective epitaxial layer is formed by performing epitaxial growth on the resultant structure. The resistance of the selective epitaxial layer is reduced to complete the local interconnection.

Method of fabricating local interconnection using selective epitaxial growth

A quick charging control circuit of a paging receiver and a control method thereof for minimizing introduction of error during reception of data by differently controlling the operation of a quick charging circuit in response to a data transmission or reception state. The quick charging control circuit of a paging receiver having a battery, a radio frequency (RF) receiving circuit, a waveform shaping circuit with a charging circuit and a quick charging circuit includes preamble detecting and synchronization code detectors for respectively detecting a preamble signal and a synchronization code among data generated from the waveform-shaping circuit, a data processor for processing batch data among the data generated from the waveform-shaping circuit, and switch controller for providing the battery saving signal to the RF receiving circuit and waveform-shaping circuit and for providing the quick charge signal to the quick charging circuit by switching the voltage of the battery with a period of a first operating state for, detecting first and second predetermined codes, and controlling an output period of the battery saving signal and the quick charge signal with a second operating state for detecting a third predetermined code in response to outputs of the preamble and synchronization code detector.

Quick charging battery saving control circuit and method for a paging

An automatic paging telephone set comprising first and second DTMF transmitters, a mode selector for selecting either a pager number recording mode, a paging mode, or a general communication mode, and a controller for controlling the telephone set according to the mode selected by the mode selector. When the telephone set is in the recording mode, the pager number data is stored into the memory of the controller. When the telephone set is in the paging mode, the controller stores the caller's telephone number into the memory thereof, and then transmts the pager number and the caller's telephone number to the paging system subscriber.
