The invention provides a method of carrying out grinding and chemico-mechanical polishing on a gallium nitride wafer. The method at least comprises the following steps of treating a gallium surface of the gallium nitride wafer: the gallium nitride wafer is fixed to a grinding platform and the gallium surface faces a grinding head; then a grinding basal plane of the gallium nitride wafer is determined by employing an XRD measuring method, the grinding head having a certain mesh number is parallel to the grinding basal plane and is pressed onto the gallium surface, and the gallium surface is ground to reach the first roughness under the action of a grinding fluid; subsequently, a grinding head having a higher mesh number is increased, the previous step is carried out till the gallium surface is ground to reach the second roughness which is less than the first roughness; finally, the gallium nitride wafer is fixed to a chemico-mechanical polishing platform, and the gallium surface is polished to the surface roughness meeting the technological requirements. The method adopts a direct grinding mode, so that the processing steps are simplified, the material consumption is reduced, the processing time is shortened, and the breakage rate is lowered.

The invention discloses a mask template transmission system used for loading a mask template to a mask table or unloading the mask template from the mask table, and the mask template transmission system comprises a template library, a manipulator and a pre alignment device. The template library is used for storing mask templates. The manipulator takes or places the mask template along the mask template storing direction of the template library, and loads the mask template or unloads the mask template along the mask template loading direction of the mask table. The pre alignment device is arranged on a transmission path of the manipulator to perform pre alignment on the mask template when the mask template is taken out from the template library by the manipulator, and after the pre alignment is completed, the manipulator loads the mask template to the mask table. The mask template storing direction of the template library and the mask template loading direction of the mask table are same, so that the manipulator can straightly go in and straightly go out. By use of the mask template transmission system, the manipulator can straightly go in and straightly go out, so that the arc motion can be avoided, the transmission path is simplified, and the system risk is reduced.

An apparatus and corresponding methods are provided for transmitting secure communications. The apparatus includes a transmitter and a receiver having an interface, a processor, and a memory. The processor instances a secure transmission function, links program data to the secure transmission function, and determines a transmission channel that does not have to satisfy security requirements to transmit the program data and the secure transmission functions. The transmitter transmits the program data and the secure transmission function across the transmission channel to the receiver, where the receiver processor instances a secure reception function corresponding to the secure transmission function and specifies a connection between a communication receiver path. The processor attaches a data output to the secure reception function corresponding to the data programmed into the transmitter, and executes and compares the reception function to the transmission function to determine if the linked data should be sent to the receiver interface.
