Abstract

The invention provides a wafer conveying device which comprises a base and a wafer supporting component fixed on the base, a plurality of supporting assemblies are formed on the inner side face of the wafer supporting component, clamping grooves are formed between the supporting assemblies, and the supporting assemblies are arranged at intervals in the direction perpendicular to the base; moreover, the inner side surface of the wafer supporting part forms an arc matched with the outer peripheral edge of the wafer, so that the wafer is stably arranged at intervals in the wafer conveying device in the direction perpendicular to the base. The wafer conveying time is shortened, the service life of a sealing ring of the wafer pre-pumping device is prolonged, the amount of particles substituted into the main detection module is reduced, and the service life of a pump for pumping air for the wafer pre-pumping device is prolonged.

Description

technical field [0001] The present invention relates to the field of semiconductor technology, in particular to a wafer transfer device, a wafer pre-pumping device and a rapid wafer transfer system. Background technique [0002] In the process of chip production, wafer inspection is a crucial link. When inspecting wafers, a wafer transfer system is required to transfer the wafers to the inspection station of the wafer inspection equipment. , also known as the transfer process. [0003] like figure 1 Shown is a schematic diagram of the bottom surface structure of a wafer transfer device in the prior art, figure 2 Shown is a schematic diagram of a wafer placed on the bottom surface of a wafer transfer device in the prior art. The wafer transfer device in the prior art has a very flat circular bottom surface, and four brackets are provided on the circular bottom surface, and the wafers are placed on the brackets. [0004] In the traditional wafer transfer system, the singl...
