Abstract: An apparatus for inspecting wafer carriers is disclosed. In one example, the apparatus includes: a housing; a load port; a robot arm inside the housing; and a processor. The load port is configured to load a wafer carrier into the housing. The robot arm is configured to move a first camera connected to the robot arm. The first camera is configured to capture a plurality of images of the wafer carrier. The processor is configured to process the plurality of images to inspect the wafer carrier.

Abstract: The invention relates to a method for preparing silica modified by a silane coupling agent. The method comprises the following steps: preparing a kind of coupling agent sol solution by mixing the solvent, water, catalyst and coupling agent; uniformly dispersing silica into the sol solution by means of ultrasonic dispersion or shear dispersion to achieve a turbid solution with uniform dispersion and ideal particle size; and then stirring the turbid solution at a constant speed to make the coupling agent sol reacting with silica to prepare highly hydrophobic silica modified by the coupling agent through controlling the temperature and reaction time. The coupling agent sol solution is obtained by a sol-gel process and silica is uniformly dispersed in the coupling agent sol solution through combined action of various dynamic means to ensure the sufficient reaction between silica and coupling agent, thus to obtain silica modified by the coupling agent.

Abstract: An overall lead-free X-ray shielding rubber compound material. The overall lead-free X-ray shielding rubber compound material uses rare earth mixture to replace lead, simultaneously adds metal tin and compounds thereof, metal tungsten and compounds thereof and bismuth and compounds thereof as shielding main materials and is further compounded with rubber to prepare the compound material which can realize the overall shielding and the complete lead-free property within the energy range of 40-170 kVp. When rare earth and bismuth materials are used, the way of combined use of two metal element inorganic compounds and unsaturated organic complexes is adopted, and the in-situ reaction and the compounding with a polymer matrix are carried out, thereby leading the shielding element disperse phase to form nano-micro-level dispersed particles.
