Embodiment Construction

[0039]Embodiments of the invention generally relate to an apparatus and methods of chemical vapor deposition (CVD), such as metallic-organic CVD (MOCVD) processes. As set forth herein, embodiments of the invention are described as they relate to an atmospheric pressure CVD reactor and metal-organic precursor gases. It is to be noted, however, that aspects of the invention are not limited to use with an atmospheric pressure CVD reactor or metal-organic precursor gases, but are applicable to other types of reactor systems and precursor gases. To better understand the novelty of the apparatuses of the invention and the methods of use thereof, reference is hereafter made to the accompanying drawings.

[0040]According to one embodiment of the invention, an atmospheric pressure CVD reactor is provided. The CVD reactor may be used to provide multiple epitaxial layers on a substrate, such as a gallium arsenide substrate. These epitaxial layers may include aluminum gallium arsenide, gallium ar...

Abstract

Embodiments of the invention generally relate to apparatuses and methods for chemical vapor deposition (CVD) processes. In one embodiment, a CVD reactor has a reactor lid assembly disposed on a reactor body and containing a first showerhead assembly, an isolator assembly, a second showerhead assembly, and an exhaust assembly consecutively and linearly disposed next to each other on a lid support. The CVD reactor further contains first and second faceplates disposed on opposite ends of the reactor body, wherein the first showerhead assembly is disposed between the first faceplate and the isolator assembly and the exhaust assembly is disposed between the second showerhead assembly and the second faceplate. The reactor body has a wafer carrier disposed on a wafer carrier track and a lamp assembly disposed below the wafer carrier track and containing a plurality of lamps which may be utilized to heat wafers disposed on the wafer carrier.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Embodiments of the invention generally relate to apparatuses and methods for vapor deposition, and more particularly, to chemical vapor deposition systems, reactors, and processes thereof.[0003]2. Description of the Related Art[0004]Photovoltaic or solar devices, semiconductor devices, or other electronic devices are usually manufactured by utilizing a variety of fabrication processes to manipulate the surface of a substrate. These fabrication processes may include deposition, annealing, etching, doping, oxidation, nitridation, and many other processes. Epitaxial lift off (ELO) is a less common technique for fabricating thin film devices and materials in which layers of materials are deposited to and then removed from a growth substrate. An epitaxial layer, film, or material is grown or deposited on a sacrificial layer which is disposed on the growth substrate, such as a gallium arsenide wafer, by a chemical vapor depos...
