Abstract
Thin-film devices, for example electrochromic devices for windows, and methods of manufacturing are described. Particular focus is given to methods of patterning optical devices. Various edge deletion and isolation scribes are performed, for example, to ensure the optical device has appropriate isolation from any edge defects. Methods described herein apply to any thin-film device having one or more material layers sandwiched between two thin film electrical conductor layers. The described methods create novel optical device configurations.

121. An electrochromic device comprising:
-
one or more material layers sandwiched between a first conductor layer and a second conductor layer; and a taper on at least one underlying layer of the electrochromic device;
wherein the taper is formed via laser ablation and wherein the taper spans more than one edge of the at least one underlying layer. - View Dependent Claims (122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135)

152. A method of fabricating an electrochromic device comprising one or more material layers sandwiched between a first conductor layer and a second conductor layer, the method comprising:
-
i) fabricating an isolation trench in at least one underlying layer of the electrochromic device;
the isolation trench separating a first section of the electrochromic device from a second section;
wherein each of the first and second sections comprise a tapered edge along the isolation trench; andii) fabricating the overlying layers of the electrochromic device over the at least one underlying layer. - View Dependent Claims (153, 154, 155, 156, 157)
