N4

TSMC this week announced a new fabrication process that is tailored specifically for high-performance computing (HPC) products. N4X promises to combine transistor density and design rules of TSMC's N5-family nodes with the ability to drive chips at extra high voltages for higher frequencies, which will be particularly useful for server CPUs and SoCs. Interestingly, TSMC's N4X can potentially enable higher frequencies than even the company's next-generation N3 process. One of the problems that is caused by shrinking sizes of transistors is shrinking sizes of their contacts, which means increased contact resistance and consequent problems with power delivery. Various manufacturers use different ways of tackling the contact resistance issue: Intel uses cobalt contacts instead of tungsten contacts, whereas other makers opted to forming contacts using selective...
