Witryna13 kwi 2024 · April 13th, 2024 - By: Brian Bailey. While only 12 years old, finFETs are reaching the end of the line. They are being supplanted by gate-all-around (GAA), starting at 3nm [1], which is expected to have a significant impact on how chips are designed. GAAs come in two main flavors today — nanosheets and nanowires.
