ABSTRACT:
A method and apparatus for molding a structure on the top surface of a substrate. Mold material is dispensed onto an area of the top surface of the substrate. The mold apparatus is positioned over the area. The mold portion of the mold apparatus is positioned above the mold material and the mold material is surrounded with a shroud of the mold apparatus. A seal is formed between the shroud and the top surface of the substrate. The pressure is reduced within the shroud to below the ambient pressure. The mold portion of the mold apparatus is lowered toward the top surface of the substrate, so that at least the outer edge of the mold portion is in contact with the mold material. The pressure within the shroud is raised to at least the ambient pressure, and the mold material is cured to form the structure.
