Evolution and Connectivity in Semiconductor Test Equipment Development

1. Overview of Testers:

Semiconductor test equipment, crucial in the chip development process, encompasses the probe table, sorter, and tester. The tester is the focal point for test functionality, with the probe table and sorter executing mechanical tasks.high voltage probe While the probe table handles wafer-level testing, the sorter is designed for chip-level testing after packaging. Testers evaluate semiconductor devices' circuit functions and electrical performance, covering DC and AC parameters, as well as function tests. Functionally, testers apply input signals, collect chip output signals, compare them with expected values, and assess chip parameters and functions under varying conditions.

2. Tester Industry Chain:

The semiconductor special equipment serves wafer manufacturing and sealing measurements, with the former process involving wafer processing equipment and other front-end tools like lithography processing equipment.wafer chuck The latter process comprises test equipment and packaging equipment. Testers play a critical role in chip parameter testing, used from IC design verification to wafer inspection during manufacturing and final product testing post-packaging. Semiconductor test equipment manufacturers primarily serve IC design companies, wafer manufacturers, and packaging test manufacturers.

3. Future Development Trends:

The semiconductor testing industry is evolving in tandem with emerging markets such as the Internet of Things, big data, artificial intelligence, 5G communications, and automotive electronics.manual prober The robust growth of photovoltaics and new energy vehicles, coupled with increasing semiconductor content in various products, fuels strong demand.
