Abstract
Substrates for use with semiconductor devices are provided. The substrates include a barcode laser etched into a metallic surface or layer of the substrate. A wall of non-metallic material may be formed on the metallic surface or layer and frame the barcode. Separately or in combination, an optically transparent encapsulant may cover a region of the metallic surface or layer that includes the barcode, where the optically transparent encapsulant reduces oxidation of metallic debris produced by laser etching of the barcode and that remains on or near the barcode. Separately or in combination, the substrate may include an electrically insulative body covered by the metallic layer and a trench formed in the metallic layer along a perimeter of the barcode and that exposes the electrically insulative body. Methods of improving readability of the barcode are also provided.
