Abstract: Embodiments of the present disclosure provide a chuck structure of a semiconductor cleaning apparatus and a semiconductor cleaning apparatus. The chuck structure includes a chuck base, a gas inlet control device, and a first gas channel and a second gas channel arranged in the chuck base and both configured to spray a gas toward the to-be-processed workpiece. A gas spray direction of the first gas channel is inclined toward the outside of the surface of the to-be-processed workpiece that is opposite to the chuck base. A gas spray direction of the second gas channel is perpendicular to the surface of the to-be-processed workpiece that is opposite to the chuck base. The gas inlet control device is configured to selectively supply the gas to at least one of the first gas channel and the second gas channel to cause the to-be-processed workpiece to be able to float at different height positions.

Abstract: The present invention provides a nanolayer-lubricated diamond grinding wheel grinding method based on a shock wave cavitation effect. In the method, after a gas pressure regulation valve is turned on, a shock wave generated by an acceleration tube pushes nanoparticles to move forward, and the nanoparticles are then accelerated by a small de Laval nozzle to acquire a high initial velocity. One wave source of a shock wave speed-increase module generates a high-frequency high-strength shock wave, to impact nanoparticles with an initial velocity, to enable the nanoparticles to be continuously accelerated downward in an axial direction of a large de Laval nozzle, until the nanoparticles are embedded on a grinding wheel surface at a maximum speed to form a nanolayer. The other wave source is used to clean impurities on the grinding wheel surface.

Abstract: An apparatus and a method for deblocking a lens, wherein the lens is blocked with a block material on a block piece. The block material is preheated by radiation. The blocked lens, the deblocked lens, and the deblocked block piece are handled by means of separate grippers. For deblocking, the lens and the block piece are held by opposing holding devices in a rotating manner, while a fluid jet acts on the block material from the side. After the deblocking, the lens and the block piece are cleaned simultaneously. Then, a holding device together with the deblocked lens pivot out from a working space. The deblocked lens is placed with the block side upward in a transport carrier. This makes possible a simple design and an optimized process sequence.
