US8795559B2
Method for forming imagers
Publication/Patent Number: US8795559B2 Publication Date: 2014-08-05 Application Number: 13/589,492 Filing Date: 2012-08-20 Inventor: Li, Jin   Boettiger ulrich c   Assignee: Micron Technology, Inc.   IPC: B29D11/00 Abstract: A micro-lens array with reduced or no empty space between individual micro-lenses and a method for forming same. The micro-lens array is formed by patterning a first set of micro-lens material in a checkerboard pattern on a substrate. The first set of micro-lens material is reflowed and cured into first micro-lenses impervious to subsequent reflows. Then, a second set of micro-lens material is patterned in spaces among the first micro-lenses, reflowed and cured into second micro-lenses. The reflows and cures can be conducted under different conditions, and the micro-lenses may be differently sized. The conditions of the reflows can be chosen to ensure that the focal lengths of micro-lenses are optimized for maximum sensor signal.
