    摘要: A method of preventing toxic gas formation after an implantation process is disclosed. Certain dopants, when implanted into films disposed on a substrate, may react when exposed to moisture to form a toxic gas and/or a flammable gas. By in-situ exposing the doped film to an oxygen containing compound, dopant that is shallowly implanted into the layer stack reacts to form a dopant oxide, thereby reducing potential toxic gas and/or flammable gas formation. Alternatively, a capping layer may be formed in-situ over the implanted film to reduce the potential generation of toxic gas and/or flammable gas.

    摘要: Implementations of the present disclosure generally relate to methods and apparatuses for epitaxial deposition on substrate surfaces. More particularly, implementations of the present disclosure generally relate to methods and apparatuses for surface preparation prior to epitaxial deposition. In one implementation, a method of processing a substrate is provided. The method comprises etching a surface of a silicon-containing substrate by use of a plasma etch process, where at least one etching process gas comprising chlorine gas and an inert gas is used during the plasma etch process and forming an epitaxial layer on the surface of the silicon-containing substrate.

    摘要: Embodiments of the invention relate to methods for fabricating a passivation layer stack for photovoltaic devices. In one embodiment, the passivation layer stack comprises a first dielectric layer of AlxOy (or SiOx) and a second dielectric layer of SixNy having a refractive index less than 2.1. The passivation layer stack has contact openings formed therethrough by a series of pulsed laser beams having a wavelength of about 300-700 nm and a pulse width of about 0.01 nanosecond to about 3 nanoseconds. Lowering the refractive index of SixNy capping AlxOy (or SiOx) in the passivation layer stack makes pulsed laser beams less selective since the SixNy absorbs less laser energy. Therefore, desired regions of the entire passivation layer stack can be removed smoothly in a single pass of pulsed laser beams at a shorter wavelength without causing damage to the neighborhood of the passivation layer stack.
