ABSTRACT:
In a baking oven for baking a relatively planar work such as semiconductor substrates, LCD panels and integrated circuit boards, a laterally elongated slot is formed in a shutter door which is moveable in the vertical direction. The oven main body is internally provided with a rack having a plurality of shelves which are each associated with the slot of the shutter door in such a manner that the work supported by each of the shelves of the rack may be aligned with the slot of the shutter door by appropriately determining the vertical position of the shutter door. Thus, by minimizing the area of the access opening of the oven main body, not only the loss of energy is minimized but also undesirable fluctuations in the internal temperature of the oven main body is minimized.
