Which Other U.S. Semi Makers Stand to Gain From Taiwanese Deal?

Also, Iomega insanity and an interview with yours truly.

A late-in-the-day dispatch

yesterday of this column noted how "wild card" assets finally might be getting value at

S3

(SIII)

and

Alliance Semiconductor

(ALSC)

. Several years ago both participated in a joint venture with Taiwan's

United Microelectronics

to create

United Semiconductor

, a private Taiwanese company that runs a semiconductor plant. Only problem: There was no way to put a value on the investment because United Semi was private.

Then, yesterday, United Micro announced plans to buy United Semi and several other joint-venture fabs in return for United Micro stock, which is traded in Taiwan. Based on the price of United Micro's publicly traded stock, analysts calculated attractive values for the S3 and Alliance holdings.

S3 and Alliance, as it turns out, weren't the only U.S. semi companies to hold stakes in the fabs being bought by United Micro.

Oak Technology

(OAKT)

, for example, owns 9.3% of

United Integrated Circuits

. Same goes for

Trident Microsystems

(TRID)

, which holds 9.3% of United Integrated assets as well. (Meanwhile,

Integrated Silicon Solution

(ISSI)

agreed to sell its position in United Integrated back to United Micro in April for its original acquisition cost, although it says it will record a gain of about $1.8 million in the June quarter on the sale. Timing is everything!) Then there's

Xilinx

(XLNX) - Get Report

, which actually records its proportional interest in

United Silicon

, another United Micro venture, as part of its own income.

Adding to the intrigue was United Micro CEO John Hsuan's comments, reported by

Bloomberg

, that efficiencies created by consolidating the fabs could cause his company's earnings to double next year.

The purchases are part of United Micro's efforts to play catch-up to

Taiwan Semiconductor

(TSM) - Get Report

, whose ADRs are the closest thing U.S. investors can get to a pure play in fabs. Most U.S. semi companies have ditched their fabs over the years. (See my colleague

Marcy Burstiner's

story on the semi shakeout.) "It used to be that foundries were nothing more than glorified

Kinkos

," says analyst Tad LaFountain of

Needham & Co.

"But during the past down cycle, Taiwanese foundries kept investing, and what they've done is shifted the bar on a process technology basis. So instead of being technology laggards, foundries are now leaders, because they can do as sophisticated a process as virtually any semi company."

Which is why U.S. companies have joint-ventured with the Taiwanese and others. Avoid the downside; participate in the upside.

No press release from Iomega

(IOM)

, but:

Treasurer Rob Simmons, who negotiated many of Iomega's financial deals with its banks, and chief spokesman Tyler Thatcher have left the company to join an upstart Internet operation. In addition, according to

SEC

filings, Simmons sold 56,000 Iomega shares, his remaining stake, at $4.94 a piece. What's more, Iomega still hasn't hired a chief financial officer to replace Len Purkis, who left a little more than a year ago. Iomega officials were not available for comment.
