The present invention is an improved method of applying electrically conductive bus bars (24) to transparent or non-transparent substrates (22) such as glass, plastic and ceramics such as for an electrochromic device, an automobile window or architectural window and many other substrates which could benefit from being heated. The present invention discloses a method for applying the bus bars with a vapor deposition process using a suitable metal composition resulting in durable bus bars. The vapor deposition process disclosed can be used with numerous metal compositions resulting in bus bars of a relatively thin cross-section without the need for high temperature firing or baking.

Why it's free to use
- Filed May 28, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended May 28, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 28, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
