A method for fabricating a composition of Zr-rich bulk amorphous alloy includes providing a weld member and a base, both made of Zr-rich bulk amorphous alloy, and welding the weld portion of the weld member to the base by a pulsed laser in a protective gas environment. Embodiments of the invention may monitor an existing network application and generate a profile on the network application based on what responses and data updates are triggered by various requests from a user. The method also includes forming an oxide layer over the nitride layer and along sidewalls and bottom of the via.
