Patent ID: 8244482

Claim:
A method of performing process control in a manufacturing process for a semiconductor product, said method comprising: monitoring a gaseous organometallic compound using a system adapted to supply the gaseous organometallic compound to a gaseous organometallic compound-utilizing manufacturing process region in said process, the system comprising (a) a sampling region for analyzing the gaseous organometallic compound, (b) a monitor in sensory communication with the sampling region, the monitor being constructed and arranged to responsively generate an output signal correlative of presence or concentration of any of (i) said gaseous organometallic compound, and (ii) at least one decomposition byproduct of said gaseous organometallic compound or a species thereof, and (c) a process controller arranged to receive the output signal of the monitor and to responsively control one or more process conditions in and/or affecting the gaseous organometallic compound-utilizing manufacturing process region; and controlling one or more process conditions in and/or affecting the gaseous organometallic compound-utilizing manufacturing process region responsive to the output signal of the monitor.
