As part of AMD's efforts to recover from the damaging delay of its Barcelona quad-core processor in 2007, the chip maker wants to spin off its two manufacturing plants, called fabs, as part of a strategy called asset light. The move will turn AMD into a fabless chip maker, reliant on contract chip makers to produce all of its chips but no longer saddled with the massive capital expenditures and R&D programs required to keep pace with advances in semiconductor technology.

Spinning off the manufacturing division would also give AMD, which is burdened with US$5 billion in long-term debt, a badly needed infusion of cash. AMD executives hope this strategy will turn the company into a more formidable competitor for Intel.

There's just one problem: AMD hasn't found a buyer.

AMD has two plants, Fab 36 and Fab 38, both located in Dresden, Germany. The newer plant, Fab 36, makes chips using 300-millimetre wafers, which offer better economies of scale than the 200mm wafers used in older plants. The other one, Fab 38, started out using 200mm wafers and is in the process of switching to 300mm wafers, a transition that should be complete early next year.

One of the reasons AMD hasn't found a buyer for these plants is that the company continues to lose money, to the tune of US$1.2 billion during the second quarter alone. That loss helped push down the value of shareholders' equity in the chip maker to $1.5 billion, down from $3 billion at the end of 2007.

During the same period, the amount of cash held by the company fell from $1.9 billion to $1.6 billion.

Coupled with expectations that AMD will continue to report net losses for the rest of this year, these financial factors make it more difficult to sell off the chip plants, said Craig Berger, an analyst at Friedman, Billings, Ramsey & Co, in a research note.
