TSMC engineer boasts of recent 6% boost to 2nm yields, passing 'billions in savings' to customers

The higher, the better.

TSMC is set to start mass production of semiconductors using its N2 (2nm-class) fabrication process sometime in the second half of next year and right now the company is doing its best to polish off the technology in terms of lowering variability and defect density and therefore improving yields. Keeping in mind that TSMC will only start offering its shuttle test wafer services for 2nm technology in January, it is unlikely that the contract chipmaker will improve yields for prototypes of actual chips that will eventually be made at 2nm. Their design enhances threshold voltage tuning, ensuring reliable operation and allowing further miniaturization of logic transistors and SRAM cells.
