Abstract

The invention relates to a graphic data high-speed transmission device of direct-writing photoetching equipment. The device comprises a graphic display device, a data receiving and processing board connected with the graphic display device through a rigid-flex board, a data conversion board connected with the data receiving and processing board through a multimode optical fiber, and a host connected with the data conversion board. The data receiving and processing board comprises a first FPGA chip, a high-speed connector, a DLP module, an SFP+ optical module and a first QSFP+ optical module, wherein the high-speed connector, the DLP module, the SFP+ optical module and the first QSFP+ optical module are connected with the first FPGA chip. The high-speed connector is connected with one end of the rigid-flex board. The data conversion board comprises a second FPGA chip, a second QSFP+ optical module and a PCI-E 3.0 X8 interface. The second FPGA chip is connected with the second QSFP+ optical module and the PCI-E 3.0 X8 interface. The first QSFP+ optical module is connected with the second QSFP+ optical module through a multimode optical fiber. According to the invention, the transmission rate of the graphic data of the direct-writing photoetching equipment can be effectively improved; rapid and accurate exposure of a graph is realized; and the unit time productivity of the direct-writing photoetching equipment is greatly improved.

Description

technical field [0001] The invention relates to the technical field of high-speed transmission of graphic data of direct-writing lithography equipment, in particular to a high-speed transmission device and method for graphic data of direct-writing lithography equipment. Background technique [0002] Laser direct writing lithography equipment is a key equipment in the production of IC (integrated circuit) and high-precision PCB (printed circuit board), in which high-speed transmission of graphic data has always been a key link in the improvement of equipment performance. After the user graphics are input into the lithography equipment, the user's original graphics need to be processed according to the extracted actual substrate parameters. A large amount of processed graphic data needs to be sent to a dedicated graphic display device (DMD) for display exposure in a short time. The speed of graphics sending directly restricts the speed of graphics exposure. [0003] With the...
