KOSDAQ-listed Sigetronics(429270) jumped more than 9% in early trading on the 15th. Buying appears to be pouring in after news that it will mass-produce silicon (Si) avalanche photodiode (APD) optical sensors used in artificial intelligence (AI)-based robots and drones.
As of 9:25 a.m. on the 15th, Sigetronics was trading at 3,380 won on the KOSDAQ market, up 280 won (9.03%) from the previous session. Sigetronics at one point rose to 4,030 won, up nearly 24% intraday, before paring gains.
Earlier in the day, Sigetronics said it is mass-producing silicon APDs for short-range measurement with wavelengths of 540 nanometers (nm) and 660 nm in the visible light range. An APD is a high-sensitivity optoelectronic device that detects faint light and amplifies signals. It is used as a key light-receiving component responsible for distance measurement in laser rangefinders as well as robots, drones, and 3D scanners.
Sigetronics analyzed that demand for precise distance measurement is increasing as AI technology expands across Smart Factory, autonomous driving, and the broader robotics industry. In step with this, it plans to complete mass production of 905 nm infrared APDs for automotive and industrial LiDAR by the end of this year. In the initial phase of the business, it will supply the currently running 540 nm and 660 nm APDs mainly to specific customers and industrial applications to build a supply chain on the order of several million units per year.
