Dear Junko - thank you very much for publishing Rockchip CEO's reply to my question on the new 2-core A-9 application processor in 28nm. So it will be in wirebond. But with plans for flip-chip also.

Hi, sranje. Rockchip's VP Chen just got back to me on your question. Here's what he wrote in his e-mail: "It’s not flipchip, still cu-wire bond, we are planning flipchip though."

I think I am the guilty one here, not articulating this whole "design" process well in the story. I will correct the story accordingly. Meanwhile, here's an e-mail I just received from Rockchip's Chen. He clarified this for us as follows: "What I meant was, after we got the chip, we were able to get the chip in end products in less than 2 months."

Dear Junko, Another very informative article - many thanks. I do have an interesting question - since you are quoting Rockchip's CEO: The RK31xx is a dual core Cortex A9 product designed for tablets and smartphones. Using Globalfoundries' high-k 28-nm process, “we can reduce cost, gain performance, but most importantly, we will reduce power consumption for tablets,” said Chen Will the package interconnect for this application processor be Cu-wire wirebond or flip-chip bumps? I am curious how much wirebond for multi-core application processors even in 28nm. Many thanks in advance if you can find and provide the answer.

Wow, a single iteration at 28nm is expensive....3-4 of those blows my mind how these guys can be competitive at all in either cycle time or cost.

Rockchip outsources most of the design work to GUC which is a TSMC affliate. My sources told me it usually takes 3 iterations (sometimes 4) to get it right. So the March to May time frame could be the 3rd try, which could be a simple metal change, or from MPW shuttle to full-mask.

I am a little doubtful about that timeline, you can't even make it through the fab in 30 days using an advanced node.

It is amazing to finish a chip design in just 2 months (started a chip in March, showed it in trade show in April and then shipped the samples in May). How much faster can they shorten the design cycle? I have no idea how innovation can take place if there is just little time for chip design to sit down to work, not even think. Personally, I don't think this can help the company to grow healthily and such strategy can't last long.
