Hori acknowledged that camera phones are not generating much nonvoice traffic revenue for operators, since it's far too expensive for users to send digital photos over a cellular network. But many operators are driven by fear that if they miss a beat in the newest trend, they could lose their subscribers to others.

As inventories tighten, price erosion is slowing. Prices that fell an average of 20% the last two years will only decline 2% this year, according to iSuppli.

We have seen steady downward pricing through the fourth quarter of this year,” said Peter Bellavigna, marketing manager of the mixed-signal business unit of Renesas Technology America Inc., a subsidiary of Renesas Technology Corp., a joint venture between Hitachi and Mitsubishi. We expect prices to stabilize but not rise significantly.”

Philips' Potvin believes that while some part prices could rise because of tight supply, such increases would not turn away buyers because the overall long-term pricing trend is downward.

Back in 1997, prices for gates were 4 cents,” Potvin said. They increased the next three years, then fell significantly the last two years. What's interesting is that prices never go as high as they were before.”

As prices begin to firm, suppliers are less apt to cut into profits to win business, according to Carl Cohen, vice president of product marketing for Avnet Silicon, part of the Electronics Marketing Group at distributor Avnet Inc., Phoenix.

They are reacting differently than they were six months ago,” Cohen said.

Also of concern to OEMs is the waning availability of less popular parts that suppliers find unprofitable to carry.

For instance, demand for general-purpose bipolar logic parts is declining, according to iSuppli. The research firm said that this has led one major supplier, Fairchild Semiconductor, to announce that it would discontinue those parts early next year. Fairchild could not be reached for comment by press time.

However, processed wafers have been succesfully thinned as well.

In this context 'processed' means that we have been developing through-wafer vias using reactive ion etching, oxide deposition, filling with poly Si and planarizing by chemical mechnical polishing,” De Moor said.

As these 'pre-fabricated' vias are currently about 30-50 micron deep, the wafers have to be thinned to this degree to obtain a through-wafer interconnect.

The thinning process is not done at IMEC, but using a commercial service – WSI, France. As far as I know, they have been thinning CMOS circuits as well. We are using carrier wafers in order to be able to further process on these thinned wafers. Lithography, etching, dicing and even flip-chip become feasable in this way,” De Moor concluded in an email to Silicon Strategies .

WSI is Wafer Services International of Evry, France.
