Intel's 14nm process delay sends Irish workers home

Keywords:P1272? 14nm process? FinFET technology? 14XM process?

In a recent report by the Irish Times, Intel was sending up to 600 Irish staffers home early from production training in the United States after deciding to delay the introduction of the P1272 14nm process at Fab 24 in Leixlip.

The workers had been training on 14nm tools in preparation for bringing that process online at Leixlip. Intel confirmed earlier this year that Fab 24 would be the overseas fab to join D1X in Oregon and Fab 42 in Arizona as sites that would run the 14nm process. Intel is thought to be spending more than $1 billion to refurbish Fab 24, and this was seen as guaranteeing the future of Intel manufacturing in Ireland for at least another iteration of Moore's Law.

The嚙確imes嚙緝eported that the ramp of 14nm production in Ireland has been pushed out six months to late 2013, attributing the delay to a slowdown in demand rather than technical problems. However, the reported delay is driving concerns that Intel may be reconsidering the ramp of the 14nm process in Ireland.

That would cause disquiet across Europe, where Intel is the biggest private-sector employer with 4,500 skilled workers.

The presence of leading-edge manufacturer in Ireland has been encouraged by the European Union. The EU sees nanoelectronics as a key enabling technology, and is reluctant to see these skills leave the continent even where they are owned by offshore companies like Intel and Globalfoundries.

This brings us to one of Intel's competitors. It is interesting to note that Intel's 14nm technology will be its second process node based on FinFET technology while Globalfoundries' 14XM process is essentially a 20nm manufacturing process with FinFETs dropped in as replacements for planar transistors.

That means Globalfoundries' 14XM due in 2014 will be among the first to transition between manufacturing process nodes without a die footprint shrink as a cost-saving driver. Along with reduced die area comes reduced power consumption, something prized by mobile chip companies.

Intel's 1272, due in 2013, should represent a shrink from the previous P1270 22nm process as well as a reduction in power consumption 每 maybe. Nothing is easy or automatic about miniaturisation at this atomic scale. Even though Intel has said it doesn't require extreme ultraviolet lithography to make it work, the use of multi-pass patterning with 193nm optical lithography is likely to have an impact on both the cost of manufacturing and yield.

If Intel can deliver the P1272 in 2013 每 whether from two or three production wafer fabs 每 it will preserve its reputation as a chip maker that, whatever its architecture and design decisions, understands semiconductor manufacturing better than others.

On the other hand, if it turns out that P1272 14nm has technical problems that require a fix 每 such as the use of silicon-on-insulator wafers as the starting point 每 a delay in delivery into 2014 will constitute a serious blow to Intel's reputation and to its position as the world's leading chip company.
