TSMC Q1 2021 Process Node Revenue: More 7nm, No More 20nm

This week TSMC has disclosed its full quarterly financial results for Q1 2021. In those results the company often explains where the revenue demand is for its technologies, and the financial split the demand brings. This number is not correlated to wafer production (although TSMC provides an overall number too), given that smaller process nodes have a per-wafer premium, but it does indicate where the demand is in the market right now. As perhaps to be expected, 7nm takes top billing, however a couple of interesting numbers come out of the data.
