Protec Mems Technology

Protec Mems Technology makes probe cards, specialised interface devices that touch the electrical contacts of chips on a semiconductor wafer to check whether each chip works correctly before the wafer is cut apart.

These custom, consumable components are supplied to semiconductor manufacturers as part of the wafer-testing stage of chip production. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company operates as a single business unit focused entirely on MEMS-based probe cards, offering both a three-dimensional and a two-dimensional variant of the product.
