Sigetronics

Sigetronics makes small semiconductor components, including protection devices, power devices, and sensors, built from silicon, which are used in products such as LED lighting, wearable health monitors, and defence equipment.

It supplies these components to customers in Korea and internationally. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company both designs and manufactures its products in-house, operating its own fabrication line called 'Multi-project FAB' that also takes on outside production work. It is actively developing power and radio-frequency devices based on gallium nitride, a compound semiconductor material, as a newer product line.
