Problem
Advanced High-Quality Silicon Nitride Substrate and Probe Guide Manufacturing Technology for High-Spec System Semiconductor Inspection Equipment
The demand for high-spec semiconductors (high concentration, high-bandwidth, ultra-fast) for 5G and AI applications is rapidly rising
Advanced inspection equipment requires precision probe guides with ultra-fine laser-processed square holes on silicon nitride substrates. This component is essential for guiding probes with high durability and heat resistance, making it a critical and increasingly in-demand solution
The stringent specifications and complex manufacturing process of silicon nitride substrates for semiconductor inspection equipment are currently dominated by a few foreign competitors. Their methods involve high-cost, high-temperature, and high-pressure techniques, leading to expensive products and limited supply
