I heard the rumor that the current yield rate of 28nm @TSMC for QCOM is approx. 30~50%.... Is it really true? What would be the standard yield for this process?

There is rarely acknowledged connection between yield and capacity in the sense that in many cases the most direct way to fix a yield problem is to restrict certain processes to go through a limited subset of available equipment. I know that we resorted to this technique many times in my past doing yield enhancement. By artificially constraining the toolset or dedicating specific pairings of tools, you get less variability in the mfg parameters and get more predictable yield. You hide the yield problem in a capacity problem.

An interesting point for this discussion: AMD paid dearly for the right to have 28-nm products manufactured at other foundries, yet 28-nm capacity is constrained. I assume that before AMD took that step they made sure they could get the capacity they needed.

Both Qualcomm and TSMC say they are happy with yields and that yields are as expected. But I don't think anyone has put a number on that.

Similarly, AMD also recently stopped relying on GlobalFoundries solely for 28 nm.

I think it's partly due to yield problems.

Hi Qualcomm, what is the current yield rate for 28nm process over at TSMC? Is it like 30%? To waht extent (%) will each OEM will be allocated for your MSM8960?

@Ricardo, since there are relatively few 28 nm customers, though growing, I suspect fewer good tools for 28 nm. It should be true across the board, i.e., for other foundries.

Better get those 28-nm capacity, if you're going to hit revenue goals. I wonder what's the reason for the shortage? High in demand? -Ricardo Member of the Patexia Semiconductor Group (http://bit.ly/HeyQJO)
