Susceptor Unit and Apparatus in Which the Susceptor Is Installed

摘要

Affords a susceptor unit in which the temperature uniformity of the susceptor baseplate is enhanced, and devices in which such a susceptor unit is installed. The susceptor unit is made up of a susceptor baseplate for carrying an object to be heated and performing heating operations on the object, and a containment for shielding the susceptor baseplate. In this susceptor unit, the shielding containment shields at least the surface of the susceptor baseplate that forms a lateral side with respect to the baseplate's heated-object-carrying face; and the difference between the maximum and the minimum separations in the encompassing interval between the lateral side of the susceptor baseplate and, facing onto the baseplate lateral side, the inside surface of the shielding containment is not more than 2.2 mm. In implementations including a cooling block, the shielding extends over the lateral side of the cooling block as well.
