Abstract


With the development of information technology, the integration of integrated circuits have become increasingly demanding, but also increasingly the increasing diameter silicon graphics linewidth shrinking, their movement dedicated production equipment lithography control requirements higher. Lithography machines commonly used PC, embedded motion control motion control card, powerful information processing capabilities of the PC and open with motion control card combined motion control capabilities to meet the needs of the lithography machine motion control. This paper focus on the design and implementation of the motion control card and its driver, the the lithography machine's motion control system to provide hardware and software support. First of all, we understand lithography machine and its motion control technology based on combining the performance of the control system of the lithography machine, make overall planning of the motion control card hardware. The motion control card access to the host computer's bus VME bus interface chip for the the VME bus dedicated interface chip VIC068A/VAC068A. DSP TMS320F2812, master chip dual-port RAM as data buffer channel interface chip and between the master chip DSP avoid bottlenecks clogging of the motion control card and PC communication. Motion control card through the D / A and switch input output access linear motor or voice coil motor drive, its motion control. Secondly, the combination of the planning of the motion control card, discuss in detail the concrete implementation of the hardware circuit of the motion control card. DSP peripheral circuit design, such as power supply, power supply monitoring and reset, simulation interface design; motion control card input and output; VME bus interface circuit realization. The motion control card is characterized by compact structure, high reliability. Finally, the motion control card can not do without the support of the driver, the motion control card driver in VxWorks, to further ensure the VxWorks hard real-time performance of the lithography system. The concrete realization of the first board support package, according to the system of the host computer hardware environment developed based environment for the development and testing of the driver. Hardware features, and then combined with the motion control card developed motion control card driver in VxWorks. The motion control card driver is a character device driver module, its drivers through of VxWorks the standard I / O system.
