1. A method of manufacturing an electrochromic window unit, the method comprising:
- (a) fabricating an electrochromic device on a non-tempered glass sheet;
(b) defining a cutting pattern for cutting the non-tempered glass sheet in order to create one or more electrochromic window panes, said cutting pattern defined, at least in part, by characterizing one or more physical features of the non-tempered glass sheet and/or electrochromic device after fabrication of the electrochromic device;
(c) cutting the non-tempered glass sheet according to the cutting pattern to create said one or more electrochromic window panes, including a first electrochromic window pane;
(d) fabricating an insulated glass unit (IGU) comprising the first electrochromic window pane; and
then(e) strengthening the first electrochromic window pane by laminating a second pane to the first electrochromic window pane of the IGU previously fabricated in (d).

Abstract
Methods of manufacturing electrochromic windows are described. An electrochromic device is fabricated to substantially cover a glass sheet, for example float glass, and a cutting pattern is defined based on one or more low-defectivity areas in the device from which one or more electrochromic panes are cut. Laser scribes and/or bus bars may be added prior to cutting the panes or after. Edge deletion can also be performed prior to or after cutting the electrochromic panes from the glass sheet. Insulated glass units (IGUs) are fabricated from the electrochromic panes and optionally one or more of the panes of the IGU are strengthened.
