Intel Warns Chip Shortage to Worsen if U.S. Bans Imports of Compound

- Cabot claims Dupont’s Rohm & Haas copied its patented method

Intel Corp. is railing against a proposed import ban on a key chipmaking ingredient, saying the move would worsen an already-perilous shortage of semiconductors.
The company is trying to dissuade the U.S. International Trade Commission from halting imports of so-called chemical mechanical planarization slurries that are sold under the name Optiplane. DuPont’s Rohm & Haas unit makes the products in Taiwan and Japan, and they’ve drawn allegations that they infringe technology owned by Illinois-based CMC Materials Inc. The ITC was scheduled to announce its final decision later Thursday but postponed it until Dec. 16. It gave no reason for the one-week delay.
