摘要:
A support boat for objects-to-be-processed including a plurality of support shelves formed in multi-stages spaced from each other by a vertical pitch for mounting a plurality of objects-to-be-processed which are to be heat treated in a vertical heat treatment apparatus; and a plurality of support bars for interconnecting the support shelves vertically spaced from each other and holding the same, the support boat comprising a light shielding plate disposed above an uppermost one or below a lowermost one of the support shelves for blocking heat rays from a heater for heating, whereby abrupt heating of central parts of those of the objects-to-be-processed which are positioned near the top or the bottom of the support boat is suppressed, and all the objects-to-be-processed can have substantially the same heat history.
