TSMC says its supply of 28nm chips continues to be low
28nm sector. Production of such chips will rise dramatically in 2013 with the number of wafer starts by TSMC expected to triple in 2013. When Mr. Chang announced last month that TSMC had close to a 100% market share in the 28nm category, analysts said that it might have indicated that the long rumored deal to supply Apple had been reached. Since Apple would be a big buyer in that market segment, the lack of another foundry name to show up in market share would seem to confirm that TSMC is selling to the iPhone and iPad manufacturer. Neither Apple nor TSMC have made any announcement about the latter supplying the Cupertino based Apple with chips.

But their 28nm is still LP process with Poly/Sion technology. HPM (HK+MG) process is still not available.

Are you sure? TSMC claims it otherwise:

They say Poly/Sion was used for 40nm, but HPM for 28nm.

"The 28nm generation represents TSMC's most energy-efficient and high-performance method of manufacturing to date. 28nm is the first generation that foundry industry starts to use high-K metal gate (HKMG) process. Still, poly/oxynitride process is offered to meet customer's time-to-market need."

Im sure its because of their low yield rate.
