The present invention provides a Cu line and method of forming the same, by which reliability can be enhanced by replacing SiN by HfOx, which plays a role as a protective layer andor an etch stop layer on a Cu line, prevents or inhibits galvanic corrosion due to Cu oxide, and inhibits or reduces additional formation of Cu oxide by gathering or scavenging oxygen atoms from \u2014OH, O2, and H2O. In a first aspect of the present invention, a method of restoring an information handling system utilizing a restore medium to provide software components over a network includes accessing the restore medium by the information handling system and loading a first set of software components capable of supplying data suitable for making the information handling system operational. The linear track provides foreaft movement substantially orthogonal to a line tangent to the center of the lateral arc. The housing is also disposed to retain the light sensor and the light attenuating filter at a fixed orientation.
