Gas injectors including a funnel- or wedge-shaped channel for chemical vapor deposition (CVD) systems and CVD systems with the same
Abstract:
The present invention provides improved gas injectors for use with CVD (chemical vapor deposition) systems that thermalize gases prior to injection into a CVD chamber. The provided injectors are configured to increase gas flow times through heated zones and include gas-conducting conduits that lengthen gas residency times in the heated zones. The provided injectors also have outlet ports sized, shaped, and arranged to inject gases in selected flow patterns. The invention also provides CVD systems using the provided thermalizing gas injectors. The present invention has particular application to high-volume manufacturing of GaN substrates.
