Abstract
A method implemented by a system for manufacturing a device having a coated transparent substrate is provided. The method includes providing the device having a transparent substrate. The method also includes coating the transparent substrate with a first transparent conductive oxide (TCO) layer in accordance with one or more parameters. The coating the transparent substrate comprises performing a physical deposition process on the transparent substrate. The method further includes determining a resistance across the first TCO layer. In addition, the method includes determining whether the resistance across the first TCO layer is within a resistance range. The method also includes in response to determining that the resistance across the first TCO layer is within the resistance range, coating the device with a second TCO layer in accordance with the one or more parameters to provide a resistance across the second TCO layer that is within the resistance range.
