GlobalFoundries produces zero defect wafers

2 posts in this topic

Getting back on the subject, we were checking several things - 32nm SOI test pattern, 28nm Bulk test pattern and mass-produced quad-core and sexa-core dies. Even though we only saw couple of hundred wafers, the number of defects was well, surprisingly low and in orders of magnitude better than some other clean room facilities we had privilege visiting. Naturally, we do not have specific information about the overall yields on the parts, as we only saw few hundred out of 35,000 wafer starts per month.

For instance, on 28nm bulk CMOS test sample, we saw three wafers that had several dozen defects, but those defects would still result in a yield substantially higher than what TSMC is able to achieve with its 40nm process [this sadly, confirms the tale of GlobalFoundries being ahead of its customers]....


32nm wafer


28nm wafer

can't wait till intel finally has some up to date competition. :)
