Abstract

The invention provides a monitoring device and a monitoring method of photoresist surplus, and a chip manufacturing device. The monitoring device comprises an acquisition unit, a computing unit and a storage unit, wherein the acquisition unit is used for acquiring the shipping quantity of various products; the computing unit is connected with the acquisition unit, and used for determining the photoresist surplus of each photoresist according to the shipping quantity of the various products, the unit photoresist dosage of the different photoresists used by the various products, and the initial quantity of each photoresist; and the storage unit is connected with the computing unit, and used for storing the photoresist surplus of each photoresist and updating the initial quantity of each photoresist. The photoresist surplus of each photoresist can be determined according to the information, so that working personnel can monitor the photoresist surplus in real time, a reliable reference base is provided for the working personnel for reasonable arrangement of a production schedule, use rates of the photoresists are increased, production waste is reduced, and the production efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of semiconductor manufacturing, and more specifically, to a monitoring device, a monitoring method and a chip manufacturing device for remaining amount of photoresist. Background technique [0002] Wafer refers to the silicon wafer used in the production of silicon semiconductor integrated circuits. Because of its circular shape, it is called a wafer; it can be processed into various circuit element structures on the silicon wafer and become a product with specific electrical functions. . [0003] In the process of manufacturing wafers, silicon wafers need to be photolithographically processed. In the prior art, a chip manufacturing device (such as a photolithography machine) is used for photolithography process, and the silicon wafer enters the interior of the chip manufacturing device, and photoresist needs to be coated on the surface of the deposited silicon wafer for photolithography. [0004...
