Inventor: ISHII YOSHIAKI
IPC: H01L21/68
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To automatically detect an abnormality during transporation of wafer. SOLUTION: Vibration sensors 13a to 13e are attached to tweezers 12a to 12e supported by the fitting block 14 of a wafer transporation device 11. When picking up a wafer 10 loaded on the boat 4 of a batch-type CVD system 1, a controller monitors detected outputs from the vibration sensors 13a to 13e and compares the present detected outputs with the predetermined set values. When the tweezer 12 rubs the surface of the wafer 10, a friction signal is issued by the vibration sensor, and a difference between the set value in the normal operation and the present detected output from the vibration sensor is observed, thereby detecting a contact with the wafer 10 accompanied with the deformation of the tweezers 12a to 12e. Therefore, a damage of wafer during transportation can be suppressed as much as possible by detecting contact of the tweezer with the wafer automatically and quickly.

If the reference call is a part of the TC connection, it is decided whether another reference call of the same caller is already switched to an output channel of an out-line 11 of the group 10. Then the apparatus 8 secures and switches one of two related output channels secured by the decision to transfer the reference call to the group 10 and to transfer an inter-call to a single out-line 12. Thus, the apparatus 8 can process both incoming reference call and inter-call.
