Phonak was groundbreaking with their Sword Chip when they lowered it to 28nM from 65nM. At the time, phone process size was around 5-7nM. From what I gather, it is tremendously expensive to develop chips on very small processes. Smart Phone manufacturers deal in enough volume to make it profitable. I’m not sure about HA manufacturers
This is true, but the good news is that smartphone manufacturers’ demand for leading edge nodes is what makes it (eventually) possible for manufacturers to gain access to smaller process sizes. In other words, once TSMC spends tens of billions of dollars to create a 5nm chip fab, they will keep that fab running as long as possible, even after smartphones have moved onto smaller processes.
I don’t know what the Deepsonic chip is in terms of process size, but I expect that HA manufacturers will continue to benefit from process shrinks, even if they are 5+ years behind what smartphones are using
