Method for constructing a wafer-interposer assembly
First Claim
1. A method for constructing a wafer-interposer assembly comprising the steps of:
- providing a wafer having a plurality of integrated circuit chips each having a plurality of contact pads; and
connecting the wafer to a wafer receiving portion of a wafer interposer to form a wafer-interposer assembly by electrical and non-temporary mechanical connection of at least some of the contact pads of the integrated circuit chips with contact pads of the wafer receiving portion, the wafer interposer having a handling portion extending outwardly from the wafer receiving portion.

Abstract
A method for reducing the likelihood of damaging a semiconductor wafer (18) and the integrated circuit chips of the semiconductor wafer (18) during handling utilizes a wafer interposer (12) having a wafer receiving portion (28) and a handling portion (30). The wafer receiving portion (28) of the wafer interposer (12) has a plurality of contact pads (22) that are electrically and non-temporarily mechanically connected to the contact pads of the integrated circuit chips of the wafer (18). The handling portion (30) of the wafer interposer (12) extends outwardly from the wafer receiving portion (28) such that the handling portion (30) is accessible to handling equipment without the handling equipment contacting the attached wafer (18).
