<p>METHOD OF FORMING CURRENT TRACKS ON SEMICONDUCTORS AbstractMethods of making current tracks for semiconductors are disclosed. The methods involve selectively depositing a hot melt ink resist containing rosin resins and waxes on a silicon dioxide or silicon nitride layer coating a semiconductor followed by etching uncoated portions of the silicon dioxide or silicon nitride layer with an inorganic acid etch to expose the semiconductor and simultaneously inhibit undercutting of the hot melt ink resist. The etched portions may then be metallizaed to form a plurality of substantially uniform current tracks.NO FIGURE</p> |
