Hi mderfox,
I understand your concern, but there are no other recourse but to stay domestic/ingenious. Luckily SMEE new DUVL 28NM lithograph is due this year and SMIC is building one now in BEIJING. Its might take a year or two for SMIC to proficiently handle the equipment but this machine can do 14nm and 7nm or even 5nm? with multi patterning. As WTAN had posted before all domestic 14nm equipment will be ready 2021 , 7nm maybe at 2022. We had to wait next year to verified all of these. hopefully you stay , a lot of news and info regarding China IC will leak out and WTAN, KYLi, Skywatcher and other experts will provide it for us. It will be an exciting year.
