[0003] In the indium phosphide substrate processing technology, in order to provide a crystal orientation reference for subsequent processes such as slicing, polishing and device fabrication, and to ensure that the crystal orientation of the final substrate meets the design requirements, and to avoid device performance degradation or failure due to crystal orientation deviation, one side of the crystal rod is ground into a flat surface before slicing the crystal rod to mark the specific crystal orientation of the crystal rod.

Move from bottom to top so that the grinding wheel 21 installed on the connecting frame 23 grinds one side of the crystal rod 6. The turntable 12 rotates so that the processed crystal rod 6 corresponds to the unloading assembly 4. The clamping driver 141 drives the two clamping plates 142 to move away from each other to release the crystal rod 6. The unloading assembly 4 removes the processed crystal rod 6. In summary, the grinding surface device of this utility model can complete the processes of loading, clamping and fixing, grinding surface, releasing and unloading without manual intervention.
