Abstract
A thin film semiconductor device includes a substrate, a stack of thin film material layers on the substrate, and a scribe fill material in the gap. The stack includes a scribe gap in at least one thin film material layer of the stack. The scribe fill material includes one or more coloring elements selected according to a difference between a baseline optical characteristics spectrum for the stack and an optical characteristics spectrum for thin film material remaining in the scribe gap.
Claims20
A thin film semiconductor device comprising:
- a substrate;
- a stack of thin film material layers on the substrate;
- and
- a scribe fill material located within a scribe gap, wherein:
- the scribe gap is an area defined by an absence of at least one thin film material layer of the stack of thin film material layers;
- and
- the scribe fill material includes at least one coloring element that is selected according to a difference between (i) a first optical characteristics spectrum for the stack of thin film material layers and (ii) a second optical characteristics spectrum for thin film material layers remaining beneath the scribe gap.
