Abstract

The invention discloses an inspection system and method for a semiconductor integrated circuit device. The inspection system includes an inspection module, a control module, an alarm module and a cloud platform. The cloud platform is used for storing and analyzing inspection data. The invention is scientific and reasonable, and can be used Safe and convenient, use the database in the cloud platform to store the detection results of each single electronic component pin, and use the data analysis sub-module, data extraction sub-module and data combination sub-module to process the stored data, which can effectively Extracting and judging the checked pin data can effectively understand which electronic components are prone to failure during the production process of semiconductor integrated circuits, which is convenient for improving the production process of semiconductor integrated circuits in the later stage, and can effectively Improving the production quality of semiconductor integrated circuits can continuously improve the production of semiconductor integrated circuits.

Description

technical field [0001] The invention relates to the technical field of semiconductor integrated circuits, in particular to an inspection system and method for semiconductor integrated circuit devices. Background technique [0002] Semiconductor integrated circuits are active components such as transistors and diodes and passive components such as resistors and capacitors, interconnected according to a certain circuit, and integrated on a semiconductor single chip to complete specific circuit or system functions. [0003] However, after the semiconductor integrated circuit is manufactured, if the electronic components have a false soldering phenomenon, the semiconductor integrated circuit will be unusable. The traditional method does not store and process the inspected data when inspecting the semiconductor integrated circuit, making it impossible Summarizing defects in the production process based on previous inspection records cannot improve and improve the production proce...
