The YES 450 PB Polyimide is a bake oven. The YES 450 PB Polyimide is for 8-inch wafers. The YES 450 PB Polyimide is specified at 3-phase, 50/60 Hz, 208 Vac.[1][2][3]
What it is
General reference — not yet source-verifiedBake ovens in semiconductor processing provide controlled heating for wafer-based materials and films. Polyimide bake ovens are used where a process needs uniform thermal treatment in an enclosed chamber rather than on an open hot plate.
How it works
General reference — not yet source-verifiedWafer bake ovens heat substrates inside an enclosed chamber to drive solvent removal, film densification, cure reactions, or other temperature-dependent changes in deposited materials. Chamber ovens commonly use filtered gas flow and controlled atmosphere options to reduce contamination and to support processes that benefit from inert or reduced-pressure conditions.
Where it fits in the process flow
General reference — not yet source-verifiedThermal bake ovens are placed in wafer process flows wherever a coated or deposited layer requires a controlled heat treatment between patterning, deposition, or etch steps. Polyimide bake steps commonly follow coating and soft-bake operations and can precede later lithography, etch, metallization, or passivation sequences depending on the device flow.
