If oxygen from the air or from outgassing of the resist is present in the furnace, the resist layer will be removed. Thus, for each process it is important to include a step with a high nitrogen flow at a lower temperature, before a high temperature for resist pyrolysis is obtained. Pyrolysis of a large amount of resist may also be a problem due to resist outgassing. | If oxygen from the air or from outgassing of the resist is present in the furnace, the resist layer will be removed.

During processing the furnace is rapidly heated by use of six long heating lamps situated around the furnace tube, | During processing the furnace is rapidly heated by use of six long heating lamps situated around the furnace tube, and cooling is done (rather slowly) by use of cooling fans. The furnace is purged with a controlable nitrogen flow. There is no vacuum on the furnace. | ||
