        Laser Micro Trimming Equipment LMT-HR Series

        With our unique optical design and alignment technology, the LMT-HR Series offer best solution for the analogue memory semiconductors' fuse cutting.

        Made-in-Japan parts are adopted for the major parts (such as laser light source, optical system, and stage etc.) to ensure stable supply.
        The size request from 4~12 inches can be accommodated.
        Our unique optical design and alignment technology enabled ultra-accurate trimming accuracy. The defective wires on the semiconductor wafer can be cut and the fuses within the IC chips can be trimmed to adjust the resistance.
