Patent ID: 8858748

Claim:
A method of making electrochromic (EC) windows, the method comprising: providing a first glass substrate; disposing, on the first substrate, EC device layers comprising at least counter electrode (CE), ion conductor (IC), and EC layers; patterning the EC device layers and cutting the first glass substrate with the EC device layers disposed thereon on as to form a plurality of EC device substrates; providing a plurality of second glass substrates; laminating the plurality of EC device substrates to the plurality of second glass substrates, respectively, such that the second glass substrates provide protection for their corresponding EC device substrates; providing a plurality of third glass substrates; forming a plurality of insulating glass (IG) units, respectively comprising first and second substrates in substantially parallel, spaced apart relation to the third glass substrates, wherein the plurality of second substrates are thermally tempered and the plurality of EC device substrates are not tempered.
