| titleOfInvention | Gas supplying apparatus and method of testing the same for clogs |
| abstract | A gas supplying apparatus of a system for fabricating semiconductor devices is tested for clogs. The gas supplying apparatus includes a carrier gas supplying device for supplying at least one carrier gas, and a plurality of reactive gas supplying devices connected in parallel to the carrier gas supplying device. The reactive gas supplying devices gasify the reactive gas carried by the carrier gas. A wafer, on which a desired layer is to be formed, is situated in a process chamber into which the reactive gas is supplied from the reactive gas supplying devices. The gas supplying apparatus also includes pressure detecing devices for detecting the pressure of the carrier gas near each of the reactive gas supplying devices. The carrier gas is supplied under a predetermined pressure to the reactive gas supplying devices. The reactive gas supplying device to be tested for clogs is rendered operational while the other reactive gas supplying devices are shut down. The pressure of the carrier gas near an outlet of the carrier gas supplying device is compared to the pressure of the carrier gas near an inlet of the reactive gas supplying device being tested to determine if the device is clogged. |
