Claim 1
Independent Claim
74 words
A METHOD FOR GROWING A LAYER OF SEMICONDUCTOR MATERIAL ON A SEMICONDUCTOR SUBSTRATE MATERIAL, COMPRISING THE STEPS OF: COATING SAID SUBSTRATE MATERIAL WITH A SEMICONDUCTOR OR METALLIC MELT CONTAINING SAID SEMICONDUCTOR MATERIAL IN SOLUTION THEREIN, WHILE SAID SUBSTRATE MATERIAL AND SAID MELT ARE IMMERSED IN A LIQUID WHICH BOILS AT A TEMPERATURE GREATER THAN THE TEMPERATURE OF SAID MELT, AND COOLING TO FORM AN EPITAXIAL LAYER OF SAID SEMICONDUCTOR MATERIAL ON SAID SUBSTRATE MATERIAL.
