US Patent:

8487304, Jul 16, 2013

Filed:

Apr 30, 2010

Appl. No.:

12/771697

Inventors:

S. Jay Chey - Hartsdale NY, US
Dustin M. Fregeau - South Burlinton VT, US
Aparna Prabhakar - North White Plains NY, US
Pavan Samudrala - White Plains NY, US
Mohammed S. Shaikh - Essex Junction VT, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H01L 23/58
H01L 23/48
H01L 23/52

US Classification:

257 48, 257750, 257758

Abstract:

An electrical connection includes a first electrical contact made of electrically conductive material. The first electrical contact is formed with a depression therein. Also included are a deformable pad, having a Young's modulus of less than 1,000,000 psi, which bears on the first contact; and a second electrical contact, made of electrically conductive material, which contacts the first electrical contact and is at least partially received into the depression. The deformable pad at least partially causes at least one lateral force on the first electrical contact, so as to induce the first electrical contact to make an electrical connection with the second electrical contact. An array of such contacts is also contemplated, as is an array of cantilevered contacts, which may or may not have depressions, and which are supported by at least one elastomeric pad, having a Young's modulus of less 72,500 psi.
