>> They passed because the costs of owning a fab exceeded the value of having one.

I guess now I have another thing I have to learn. Such as whether it was 200mm or 300mm ? How up-to-date or obsolete the equipment was ? etc.... If I can find some info, I'll post what I see.

About that SIS fab.

Now just because I found this article outlining some of SiS fab problesm does not mean they are all true. It looks like the SiS fab was 8", not up-to-date, its owner was having trouble getting enough output, needed more expertise or expense to upgrade its process, etc.... Likely, VIA didn't think it could make it work any better for itself.

It seems that it is not so profitable for Taiwanese core-logic developers to own a manufacturing facility these days. SiS has been unable to fulfil the demand on its products for a long time already. On the other hand they did not succeed in building additional 12-inch fab due to loads of reasons: initially, the location of the fab was chosen in the Tainan Science-Based Industrial Park (TSIP), but it was unveiled afterwards that a high-speed rail-line would be build nearby, creating vibrations that would affect the manufacturing process of semiconductors. Later the company decided to found their fab in Luchu Science-Based Industrial Park (LSIP) in Kaohsiung County, but delayed its plans due to global economic downturn and overall market conditions. Since the company now formed their strategic alliance with one of the biggest contract manufacturers, it does not make sense to build another own fab. Moreover, it is logical to sell even the current fab off so that not to spend money on development and deployment the new manufacturing processes. At the moment there are rumours floating around that UMC is likely to buy SiS’ 8-inch fab even despite of the fact that the former already owns a number of 8-inch facilities in Taiwan.
