Electronic cart for wafer carrying

Abstract

The invention discloses an electronic cart for wafer carrying, which comprises a mobile platform, damping wheels are arranged at the bottom of the mobile platform, a bearing platform is arranged on the surface of the mobile platform, a weighing sensor is arranged between the mobile platform and the bearing platform, and a reader is further arranged at the bottom of the bearing platform. The surface of the bearing platform is used for placing a wafer box, an electronic tag is arranged on the wafer box, a fence is further arranged on the portion, on the periphery of the bearing platform, of the movable platform, a push-pull handrail is arranged on one side of the movable platform, and a display module is arranged on the push-pull handrail. A battery and a controller are arranged in the mobile platform, the controller is connected with the reader, the weighing sensor and the display module, and the battery supplies power to the weighing sensor, the reader, the display module and the controller. The effect of transmitting materials and corresponding information in the conveying process can be achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor manufacturing, in particular to an electronic cart used for wafer handling. Background technique [0002] Wafers are the basic raw materials for the manufacture of semiconductor devices. Ultra-high purity semiconductors are prepared into wafers through crystal pulling, slicing and other processes. The wafers undergo a series of semiconductor manufacturing processes to form extremely tiny circuit structures, which are then cut, packaged, and tested to become chips, which are widely used in various electronic equipment. . [0003] There are many links in the manufacturing process of semiconductor wafers. It is necessary to turn the wafers through the wafer box. Since the whole process cannot be monitored in the logistics link, there is a lack of information, especially the transportation of the wafer box. In the process, it leads to the need for retrospective verification, which affects the ...
