Abstract

A method for enhancing hydrogenation of an oxide-coated polycrystalline silicon thin-film transistor or devices includes depositing a metal capping layer on the device prior to hydrogenation. In addition, a method for batch hydrogenation of substrates or plates carrying the oxide-coated polycrystalline silicon devices includes placing the plates in a downstream flow from a hydrogen plasma.
