In an embodiment, a method is provided for accessing a resource. Embodiments include laser thermal annealing employing an NH3 flow rate of about 200 to about 2,000 sccn. A through via hole, including a first section formed in the lower mold layer and a second section formed on the first section can also be provided. This is followed by heating, forming, and quenching the crystal sufficiently rapid to limit the formation of alloy precipitates to an amount which retains hyperelastic composition and properties of the crystal. The process applies to both cleaning and coating of the workpiece, wherein coating is achieved via sacrificial anodes. The present invention also discloses a display substrate and a display apparatus.
