Semes Ships 5,000th Unit of Mass-Produced Semiconductor Probe Station

On April 8, SEMES, the semiconductor equipment subsidiary of Samsung Electronics, announced that it had held a shipment ceremony for the 5,000th unit of its next-generation inspection equipment, the probe station (SEMPRO).

Since the start of mass production in 2003, SEMES reached the shipment of its 1,000th unit in 2014, the 2,000th in 2020, and has increased by 1,000 units every two years, achieving the 5,000th unit shipment in 22 years.

The probe station is an automated system connected to a tester to inspect the electrical characteristics of each chip (die) formed on a wafer during the semiconductor EDS (Electrical Die Sorting) process, sorting chips into good and defective units.

The SEMES probe station contributes to the efficiency of the EDS process, based on industry-leading heat control during high-bandwidth memory (HBM) testing and improved accuracy for high-load contact. The company is now manufacturing smart factory-type equipment with unmanned automation features.

Choi Byunggab, Head of Test and Packaging, stated, "The shipment of the 5,000th unit is a testament to the quality and reliability of our equipment," adding, "As demand for high-performance semiconductors such as AI and HBM grows and wafer testing processes become more complex, we have secured a technological edge in HBM testing compared to competitors."

The SEMES probe station received the Best of the Best award in the industrial design concept category at the Red Dot Design Awards in 2018, one of the world's top three design awards.
