What it is

The YES 450 PB 6-8 P-G is a polyimide bake oven. The model is 450 PB 6-8 P-G. The oven is designed to operate at 60 Hz with a voltage of 208 Vac, three-phase, three-wire plus ground.[1]

How it works

General reference — not yet source-verified

Polyimide bake ovens typically use forced convection heating to circulate hot gas evenly over the wafers. A programmable logic controller manages the temperature profile, which may include multiple soak and ramp stages. Some systems incorporate an inert gas environment, such as nitrogen, to prevent oxidation during curing.

Where it fits in the process flow

General reference — not yet source-verified

The polyimide bake oven is used after the polyimide precursor has been applied to the wafer by spin coating. The oven performs the thermal curing step that converts the liquid precursor into a solid polyimide film. Downstream processes may include photolithography, etching, or further deposition steps that pattern or encapsulate the polyimide layer.

Applications

General reference — not yet source-verified

Polyimide bake ovens are used to cure polyimide films that serve as stress buffer layers, passivation coatings, or dielectric layers in semiconductor devices. Applications include wafer-level packaging, MEMS, and other processes where polyimide provides thermal stability, electrical insulation, or mechanical stress relief.
