BNSR is a semiconductor process diagnostics company that develops and manufactures Sensors on Wafer (SoW), a critical consumable for inspecting semiconductor etching equipment, successfully entering a market long dominated by KLA. Its proprietary radial sensor distribution technology places sensors evenly across the wafer to minimize blind spots and improve data reliability, while unique electronic component embedding and plasma shielding structures enable stable measurements even in plasma-active environments and extreme temperatures ranging from -40℃ to 140℃. BNSR’s product lineup includes the LT Series for room-temperature use and the CY Series for cryogenic conditions. The company became the first in the world to earn TSMC’s certification for cryogenic SoW standard equipment and has validated its technology and market potential through supply partnerships with leading global semiconductor equipment makers such as AMAT and TEL.
