A gas injector includes a base plate, a middle plate, and a top plate. The base plate, middle plate, and top plate are configured to flow a purge gas between the base plate and the middle plate and to flow a precursor gas between the middle plate and the top plate. Another gas injector includes a precursor gas inlet, a lateral precursor gas flow channel, and a plurality of precursor gas flow channels. The plurality of precursor gas flow channels extend from the at least one lateral precursor gas flow channel to an outlet of the gas injector. Methods of forming a material on a substrate include flowing a precursor between a middle plate and a top plate of a gas injector and flowing a purge gas between a base plate and the middle plate of the gas injector. |
