摘要:
An improved p-type semiconductor alloy film, improved photovoltaic and photoresponsive devices incorporating such films and radio frequency and microwave glow discharge methods for fabricating same. The improved semiconductor alloy films preferably include at least silicon deposited by the glow discharge of a compound containing at least silicon and a boron species that remains substantially mono-atomic as it is incorporated into the silicon matrix. The p-type film is particularly stable, is characterized by a non-narrowed band gap, reduced bulk stress, improved morphology, growth and adhesion and reduced peeling and cracking. The substantially intrinsic film is characterized by substantially reduced Staebler-Wronski degradation. The method includes the novel step of introducing a boron species that does not form higher order boron hydrides or other boron polymers or oligomers in a glow discharge plasma.
摘要:
A method of forming a high flux of activated species (34), such as ions, of an energy transferring gas (A) by employing a substantial pressure differential between the pressure adjacent the aperture (26) in a first conduit (24) through which the energy transferring gas is introduced into a vacuumized enclosure (12) and the background pressure which exists in said enclosure. In one embodiment, the flow rate of the energy transferring gas flowing through said first conduit, when taken in conjunction with said pressure differential, causes the high flux of activated species of the energy transferring gas to collide with a precursor deposition/etchant gas, remotely introduced into the enclosure through a second conduit (60), for forming deposition/etchant species (65) therefrom. In an alternate embodiment, the pressure differential causes those activated species, themselves, to be either deposited upon or etched away from the surface of a remotely positioned substrate (50).
