Abstract:
A method of fabricating an interconnection element having a contact tip structure, comprising:forming a contact tip structure on a sacrificial substrate; prior to constructing the contact tip structure, providing a selected topography in an area of the sacrificial substrate by imposing an articulation in the sacrificial substrate, wherein the contact tip structure is formed on the area of the sacrificial substrate which is formed with the selected topography; attaching an interconnection element to the contact tip structure to form a first structure having the interconnection element and the contact tip structure; and removing the contact tip structure from the sacrificial substrate wherein the first structure is resilient after said removing of the contact tip structure.
