Abstract

A boat for semiconductor wafers has reduced contact surface area with the wafer, thereby preventing distortion of the wafer during heating. The boat has an upper member; a lower member, a plurality of wafers being loaded between the upper member and the lower member; and a plurality of support members vertically extended between and connecting the upper member to the lower member for supporting the wafers. A plurality of slots are successively and horizontally formed in each of the support members, and the peripheral edge of the wafer is inserted therein, wherein a hemisphere-shaped protrusion is formed inside the slot, and the bottom surface of the wafer contacts and is supported by each hemisphere-shaped protrusion at a single contact point.
