Problems solved by technology

[0003] The existing semiconductor chips need to be cleaned during the production and processing process. After cleaning, they need to be dried and dehumidified. Therefore, a dehumidification device is required to use the existing dehumidification method for dehumidification. However, the existing dehumidification method is relatively simple, just using a fan Air-dry the chips conveyed on the surface of the conveyor belt, but the surface in contact with the conveyor belt cannot be dried, and the dehumidification and drying effect is not good, and the dehumidification is not complete, which affects the subsequent process

Abstract

The invention belongs to the field of semiconductor chip processing, and particularly relates to a semiconductor chip dehumidification method. A dehumidification system used in the dehumidification method comprises a first conveyor belt, a first fan, a second conveyor belt and a second fan, wherein the first fan is mounted on the upper side of the surface of the first conveying belt, and an air outlet of the first fan directly faces the upper surface of the first conveying belt. According to the method, when a single surface of a chip is air-dried and dehumidified through the fan, a water absorption cotton layer on the surface of the first conveying belt can absorb water molecules on the other surface of the chip, and then the surface of the semiconductor chip is air-dried and moisture-absorbed again through a guide plate, so that the semiconductor chip can be thoroughly dried, therefore, the situation that the subsequent process is influenced by incomplete dehumidification is effectively avoided.

Description

technical field [0001] The invention relates to the field of semiconductor chip processing, in particular to a semiconductor chip dehumidification method. Background technique [0002] Semiconductor chip: A semiconductor device that can realize a certain function is made by etching and wiring on a semiconductor sheet. Not only silicon chips, but also gallium arsenide (gallium arsenide is poisonous, so some inferior circuit boards should not be curious to decompose it), germanium and other semiconductor materials. Semiconductors are also trendy like cars. In the 1970s, American companies such as Intel had the upper hand in the dynamic random access memory (D-RAM) market. However, in the 1980s when high-performance D-RAM was required due to the emergence of large-scale computers, Japanese companies came out on top. [0003] The existing semiconductor chips need to be cleaned during the production and processing process. After cleaning, they need to be dried and dehumidified...
