Title: Wafer boat
Inventor: MORISHIMA KAZUHIRO
IPC: H01L21/22
Filed: 1987-04-20
Abstract: PURPOSE:To make it possible to apply gas on the surface of each wafer uniformly even if the interval between the wafers is close, by alternately setting the neighboring wafers, applying the gas on the protruding part of the wafer, moving the applied gas in the direction of the central part of the wafer, and making the gas flow in this way. CONSTITUTION:When a diffusing furnace 1 is heated and gas is sucked through a sucking port 2, the gas hits the protruding part at the side of a wafer 5. The gas is turned and flows in the direction of the central part of the wafer 5. Thus the gas is uniformly applied on the surface of the wafer 5. In a similar way, the gas is applied to the sideward protruding part of each wafer 5 and flows in the direction of the central part of the wafer 5. Therefore, the gas is uniformly applied on the surface of each wafer. Since the neighboring wafers are deviated, the substantially same state, in which the pitch between the neighboring wafers is made large and the wafers are set, is obtained. Therefore, turning of the gas becomes excellent, and the gas is uniformly applied. Even if a boat 4 is not rotated, the gas is applied on the surfaces of the wafers sufficiently and uniformly.
