G 4 MOCVD
The Aixtron G 4 MOCVD is a metal organic chemical vapor deposition system. The Aixtron G 4 MOCVD supports 4-inch wafers. The Aixtron G 4 MOCVD is configured for EPI processing.[1][2][3]
What it is
General reference — not yet source-verifiedA metal organic chemical vapor deposition system is a deposition tool used to grow thin films on wafers from reactive precursor gases. MOCVD tools are commonly used where crystalline or compound semiconductor layers must be formed with controlled composition and thickness.
How it works
General reference — not yet source-verifiedMOCVD systems generally deliver vapor phase precursors into a heated reactor, where the gases decompose or react at the wafer surface to form a deposited layer. MOCVD reactors generally combine gas delivery, pressure control, pumping, and temperature control so that film growth occurs under controlled chemical conditions.
Where it fits in the process flow
General reference — not yet source-verifiedDeposition tools such as MOCVD systems are used in process flows after a substrate has been prepared and before later patterning, etch, implant, metallization, or passivation steps, depending on the device design. Epitaxial deposition tools are used when a process requires a grown layer with specific material properties before downstream device fabrication continues.
