Foxconn announced its $10 billion plan at the White House in July, saying the LCD plant would occupy 1,000 acres in the state's south east.

The outfit said it will begin by setting up a back-end packaging line, high-precision molding line and end-device assembly line. It may also start importing glass from Taiwan, China and Japan.

The three facilities will require a combined investment of under $1 billion, Louis Woo, special assistant to Foxconn Chairman Terry Gou, told Reuters on Monday. The jobs they generate will fall under the 13,000 positions that Foxconn has said its $10 billion investment would directly create, Woo said.

Wisconsin's Republican-controlled state assembly voted last week to approve a bill aimed at establishing a $3 billion incentive package for the plant, despite objections that the sweeteners for the project were far too much and it would take the state 25 years before it got its money back.

The bill next needs approval from the joint finance committee - with members from both the Assembly and state Senate - as well as from the Senate before going to the governor.

Foxconn expects a final decision on the matter in September, and if the bill wins final approval, the firm will immediately begin land survey work, Woo said.

He also said Foxconn is considering investing in other states, but has not finalised any plans.
