Samsung is reportedly dealing with defects in its foundry products – and that doesn’t look good for its burgeoning foundry business. According to the report by Business Korea, the defects stemmed from the use of contaminated equipment on one of the firm’s 8-inch wafer lines located in the company’s Giheung Plant.
According to a Samsung Electronics official the contaminated process has been cleaned up, preventing any further damage. Contamination of this kind is often disastrous, as the results of foreign particles making their way into the lithographic chip-making process is only spotted in the final wafer, and each contaminated wafer could contain hundreds of dies. Samsung estimates the recent damage to tally at billions of Korean won – or millions of US dollars.
One industry insider speculates that the damage could be far greater than initial reports, however. They claim “Samsung has not calculated the exact amount of the damage yet,” and that “the loss can be much larger than the company’s estimate.” We won’t know the full extent of the damage likely until Samsung’s next financial reports come around.
