The Taiwanese company pleaded guilty to the crime late last year and agreed to pay a US$220 million fine.

Former President Jau-Yang Ho pleaded guilty to participating in the conspiracy from September 2001 through November 2006, the DOJ said. He agreed to pay a $50,000 fine and serve 14 months in jail. He also said he'll help the DOJ in its ongoing investigation into the conspiracy.

Ho's colleague, Chu-Hsiang Yang, formerly a director of sales at Chi Mei, also pleaded guilty to participating in the scheme, from April 2004 through November 2006. He was sentenced to pay a $25,000 fine and spend nine months in jail.

The agency said the men, both residents of Taiwan, met with other TFT-LCD makers and agreed to sell the panels at certain prices.

So far, six companies including Chi Mei have pleaded guilty for their involvement in the plan, the DOJ said. They've been ordered to pay fines totaling $860 million. Also, 11 people have been charged.
