According to the graph on the linked page below, the cost per transistor hit a minimum at 28nm (which was the last of the planar designs), and has risen slightly with FinFET (which is not as reliable as planar). "The chart below is from Marvell’s 2020 investor day. The bar for 28nm was approximately 2011-2012." Cost is per 100 million gates. 90nm - $4.01 65nm - $2.82 45/50nm - $1.94 28nm - $1.30 20nm - $1.42 16/14nm - $1.43 10nm - $1.45 7nm - $1.52 https://www.fabricatedknowledge.com/p/the-rising-tide-of-semiconductor https://www.fabricatedknowledge.com/p/the-rising-tide-of-sem...
