Description

Method for accelerating driving program of optical fiber loop main controller of ion implanter

Technical Field

The method is applied to the ion implanter software, can improve the driving speed of the optical fiber loop main controller, and can avoid the problem of data display jamming in the beam-adjusting interface, thereby improving the use experience and the beam-adjusting efficiency of the software.

Background

Ion implanters are important equipment in microelectronic fabrication. In the ion implanter software, the fiber loop main controller driver is a very important driver. It controls the input and output of nearly thousands of digital and analog quantities in an ion implanter. These digital and analog ports, in turn, control the power supplies, valves, and pumps of the ion implanter. In establishing a beam interface of ion implanter software, a large amount of power supply and Faraday cup feedback data need to be displayed in real time. These data are all from the fibre loop master controller driver. When the driving speed of the optical fiber loop main controller is low, the problem of blockage of data updating of the beam adjusting interface can occur, and the use experience and the beam adjusting efficiency of software can be reduced. Therefore, the speed of driving the optical fiber loop main controller is significant.

Disclosure of Invention

The invention discloses a method for accelerating a driver of an optical fiber loop main controller of an ion implanter, which is mainly used in ion implanter software. There is a need for real-time display of a large amount of power supply and faraday cup feedback data in a beam-conditioning interface of an ion implanter. The method can improve the driving speed of the optical fiber loop main controller, and avoid the problem of data display jamming of the beam-adjusting interface.

The invention is realized by the following technical scheme: the optical fiber loop main controller board card (1), the memory buffer (2), the timer (3), the driver (4) and the interface program (5).

The method is characterized in that: and after sending a read operation command to the optical fiber loop main controller board card (1) each time, the driver (4) backs up all IO (input/output) returned by the optical fiber loop main controller board card into a predefined memory buffer (2), and simultaneously starts a timer (3) to start timing. When the interface program (5) calls the driving program (4) to read a certain IO amount, if the timing value of the timer (3) is smaller than a set value at the moment, the driving program (4) directly reads the backup IO amount required by the interface program (5) from the memory buffer (2), if the timing value is larger than the set value, the reading operation command is sent to the optical fiber loop main controller board (1) again, all digital and analog port IO amounts returned by the optical fiber loop main controller board (1) are backed up in the memory buffer (2), the timing value of the timer (3) is reset at the same time, and finally the IO amount required by the interface program (5) is returned.
