Title: Semiconductor manufacturing equipment
Inventor: MATSUNAGA TATSUHISA
IPC: H01L21/31
Filed: 2000-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent the thermal effect of a diffusion CVD system on wafers by suppressing the size increase of the CVD system. SOLUTION: A first temporary placing stage 5 on which treated board 21A is temporarily placed, and a second temporary placing stage 6 on which an empty boat 21B is temporarily placed, are set up at positions from a heat treatment stage 4 set up on the axial line of a process tube. Boat transferring equipment 30 which transfers the boards 21A and 21B is provided among the stages 4, 5, and 6. Since the high-temperature treated boat 21A carried out of a treatment chamber is transferred to the first temporary placing stage 5 and retreated, the thermal effect of the boat 21A on the new wafers transferred to the empty boat 21B is prevented. Since the radius of gyration of the arm of the boat transferring equipment 30 can be reduced by executing the replacement and transfer of old and new boats among the stages 4, 5, and 6, the size increase of the diffused CVD system can be suppressed.
