Abstract
A catalytic liquid toner is electrostatically printed on an amorphous silicon layer (or a substrate that is to support such a layer), in an image-wise fashion. After the liquid toner is dried, the amorphous silicon layer is heated, preferably using rapid thermal annealing, to approximately 550° C. for about 2 minutes to cause the toned areas to be converted to polysilicon. The toner used during the printing action is a dispersion of resin particles which contain a metallic catalyst, such as palladium, nickel or chromium.
