ABSTRACT:
A semi-conductor based imager includes a microlens array having microlenses with modified focal characteristics. The microlenses are made of a microlens material, the melting properties of which are selectively modified to obtain different shapes after a reflow process. Selected microlenses, or portions of each microlens, are modified, by exposure to ultraviolet light, for example, to control the microlens shape produced by reflow melting. Controlling the microlens shape allows for modification of the focal characteristics of selected microlenses in the microlens array.
