A semiconductor device defective inspection system

Abstract

The invention discloses a defective detection system for semiconductor devices, which comprises a machine base, a frame, a transmission roller shaft, a conveyor belt and a detection mechanism. The inner side of the circumscribed sleeve body is rotatably connected with a rotating shaft, the outer end of the rotating shaft is fixedly connected with a support arm, the lower end of the shelf plate is slidably connected with a sliding joint plate, and the lower ends of the two sets of sliders are fixedly connected with A splint, and a counting and statistical mechanism is installed on the outer end of the base. In the present invention, first, the semiconductor device is clamped by the splint, so that the detection system can accurately capture the defective chips, preventing the defective chips from affecting the user experience; Devices are transported separately to help manufacturers quickly screen defective semiconductor devices. Finally, the production yield of semiconductor devices is calculated, which is conducive to the staff's control of product quality in the later stage.

Description

technical field [0001] The invention relates to the technical field of semiconductor production, in particular to a detection system for defective semiconductor devices. Background technique [0002] Semiconductors refer to materials whose conductivity is between conductors and insulators at room temperature. Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields. For example, diodes are devices made of semiconductors. . [0003] No matter from the perspective of technology or economic development, the importance of semiconductors is very huge. The core units of most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. After the existing semiconductor devices are processed and produced, some semiconductor devices will have certain defects. They need to go through a series of tests to screen ...

Problems solved by technology

[0003] No matter from the perspective of technology or economic development, the importance of semiconductors is huge. The core units of most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors. After the existing semiconductor devices are processed and produced, some semiconductor devices will have certain defects. They need to go through a series of tests to screen out these defective products to ensure that the manufactured semiconductor devices can be used when they are put into use. However, after the existing semiconductor device inspection system detects defective semiconductor devices, it is difficult to distinguish defective products from normal semiconductor devices in a timely and effective manner, resulting in some missed defective products not being screened in time Going out, affecting product quality after entering the market
