In honor of this grand event, Unicom Technology has sponsored this conference and brought several instruments to participate in the exhibition. Among them, the Profilm3D optical profilometer, with its low cost, high precision and an extremely large field of view area, makes optical profilometer measurement more affordable. The Filmetrics R50 four-probe resistivity meter and the Filmetrics film thickness gauge can measure the thickness of all didielectric and semiconductor materials, and are suitable for measuring smooth semi-transparent films.
