Appeal No. 2003-1656
Application No. 09/725,973
Oozu by requiring a microlens layer and by requiring that the
infrared filter layer be formed as a planarizing layer.
According to the Examiner, it would have been obvious for an
artisan with ordinary skill to dispose a microlens layer on the
infrared filter layer 315 of Oozu in view of and for the reasons
taught by Chiulli (see the paragraph bridging columns 7 and 8),
and, toward this end, it would have been obvious to form Oozu’s
infrared filter layer 315 as a planarizing layer in order to
obtain the planarizing benefits taught by Jedlicka with respect
to planarizing his infrared filter layer 40 (e.g., see the
paragraph bridging columns 4 and 5 and lines 34-52 in column 5).
In this regard, Jedlicka teaches that one of the functions of his
planarizing (and infrared filter) layer 40 is “so that subsequent
layers ... will be applied evenly over the relatively smoothed out
surface of polyimide layer 40" (column 5, lines 49-52), and this
teaching would have led the artisan to form Oozu’s infrared filter
layer 315 as a planarizing layer so that the subsequent microlens
layer formed thereon will be applied evenly and uniformly in
accordance with the teachings of Chiulli (again see the paragraph
bridging columns 7 and 8 and especially the “uniform layer”
desideratum in line 11 of column 8).
