Abstract:
1. A process for the manufacture of a wafer substrate for use in the semiconductor industry, comprising: arranging a first compressive rotatable roller member and a second compressive rotatable roller member in an opposed, compressibly displaceable, spaced-apart relationship, with a pattern plate disposed therebetween, said pattern plate having a plurality of aligned through-holes arranged thereon; filling said through-holes with a molten solder; compressing said solder and pattern plate between said first and second opposed compressive rotatable roller members to compact said solder therein and cleans said pattern plate of excess solder; chilling said pattern plate to solidify said molten solder in said through-holes; and removing said pattern plate from said spaced-apart compressive rotatable roller members.
