Abstract: An apparatus for monitoring beam currents of an implanter is provided. The apparatus includes a beam-sensing unit for sensing the beam currents; a position-determining unit for determining scan positions; and a computing unit. The computing unit is configured to perform the functions of receiving the beam currents from the beam-sensing unit; receiving the scan positions from the position-determining unit; and determining a drift status of the implanter from the beam currents, wherein the computing unit is configured to receive the beam currents and the scan position periodically between a starting time and an ending time of a scan process of the implanter.

Abstract: A system for acquiring semiconductor process status information. An equipment server outputs a start command according to a HSMS protocol to a computer system server, which converts the start command from the HSMS protocol to a RS232 protocol and outputs the converted command to a protocol converter. The protocol converter converts the start command from the RS232 protocol to a RS485 protocol and outputs the converted command to an AD/DA module. The AD/DA module converts the start command from the RS485 command to an analog signal and outputs the converted command to an external sensor, which acquires semiconductor equipment status information as initiated by the start command. The acquired status information is then sent on a reverse path to the start command, undergoing successive conversion and output until reaching the equipment server.
