Draft specs:

800°C - 1200°C for thermal oxidation of silicon
Precise temperature ramp for process control
A large enough diameter to hold at least a die at a time (but ideally something that can hold at least 100mm wafers).

Here is a DIY tube furnace: https://www.projectsinflight.com/2023/06/14/high-temp/

I would prefer to get a properly built device but if that isn't happening, it seems we could build our own?
