Contamination at Samsung 8" Giheung Fab

BusinessKorea reports that Samsung foundry was affected by defects at its Giheung fab that manufactures 90nm image sensors among other products. "The defects were caused by the use of contaminated equipment on an 8-inch wafer line located in Samsung Electronics' Giheung Plant in Korea. A Samsung Electronics official acknowledged that defective products were found, but said that the process has already been normalized and that the damage is estimated at billions of Korean won.

However, some experts say that the damage may be much more than estimated by Samsung Electronics. "I understand that Samsung has not calculated the exact amount of the damage yet," said an industry insider. "The loss can be much larger than the company’s estimate.”
