Abstract
The present invention provides a thin-film structure that includes an etch-stop layer having a first side and a second side, a patterned compensation layer for dissipating thermal energy, and an etch-vulnerable layer, where the etch-stop layer substantially impedes etching. The patterned compensation layer is adjacent the first side of the etch-stop layer, and the etch-vulnerable layer is adjacent the second side of the etch-stop layer.
