TOOL APPLICATIONS OF CVD DIAMOND THICK FILMS ARE REVIEWED. THE FIRST APPLICATION IS CUTTING TOOLS. CUTTING PERFORMANCES OF SMALL-DIAMETER ENDMILLS AND INSERTS WERE EXAMINED. THE SECOND IS WEAR RESISTANT TOOLS; TAB (TAPE AUTOMATED BONDING) TOOLS. THESE ARE USED IN BONDING SEMICONDUCTOR DEVICES WITH LEAD WIRES. EXPERIMENTAL RESULTS ON CVD DIAMOND TAB TOOLS ARE DESCRIBED.
