| abstract | METHOD OF FORMING A DEEP ETCH LITHOGRAPHIC PLATE WHICH COMPRISES THE STEPS OF EXPOSING A HYDROPHILIC METAL SUBSTRATE BEARING A LIGHT-SENSITIVE LAYER CAPABLE OF DEVELOPING A RD OF 1.0 TO 2.2 TO ACTINIC RADIATION TO PRODUCE A POTENTIAL RD OF 1.0 TO 2.2, DEVELOPING SAID LIGHT-SENSITIVE LAYER WITH WATER-INSOLUBLE POWDER PARTICLES USING PHYSICAL FORCE TO EMBED THE POWDER PARTICLES IN THE LIGHT-SENSITIVE LAYER, REMOVING NON-EMBEDDED POWDER PARTICLES, FUSING THE WATER-INSOLUBLE POWDER PARTICLES TO THE HYDROPHILIC METAL SUBSTRATE BY HEATING, ETCHING THE HYDROPHILIC METAL SUBSTRATE IN THE AREAS UNPROTECTED BY THE FUSED WATER-INSOLUBLE POWDER PARTICLES, APPLYING A FILM FORMINGG, AROMATIC HYDROCARBON INSOLUBLE, HYDROPHOBIC POLYMER TO THE PLATE FROM A POOR SOLVENT FOR THE FUSED POWDER PARTICLES, AND REMOVING THE FUSED POWDER PARTICLES AND HYDROPHOBIC POLYMER ADHERING THERETO WITH A POOR SOLVENT FOR SAID HYDROPOBIC POLYMER. |
