  • Method of forming a solid article
    Patent number: 5219712
    Abstract: In a method of forming a solid article of predetermined shape from a liquid which can be cured by exposure to radiation, a surface upon which the article is to be formed is provided. A predetermined region of the surface is exposed to a beam of radiation. Liquid is then supplied to an unexposed region of the surface such that a solid barrier, defining a surface of the solid article, is created at the interface of the liquid and the beam. The solid barrier is effective as a mold to contain the liquid which has been supplied but not yet cured until this liquid is cured. Such a method can be used to encapsulate a microelectronic device.
