Abstract

A fall-proof apparatus for cleaning semiconductor devices is provided. The fall-proof apparatus comprises: a nozzle (102) connecting with a carrier (101); a megasonic/ultrasonic device (105) fixing on the carrier (101); and a sensor (104) detecting the distance between the megasonic/ultrasonic device (105) and the carrier (101) to determine whether the megasonic/ultrasonic device (105) is loose and going to fall. The megasonic/ultrasonic device works with the nozzle during a cleaning process. A chamber with the fall-proof apparatus is also provided.
