Method for fabricating interconnect having support members for preventing component flexure

Abstract

A test carrier and an interconnect for testing semiconductor components, such as bare dice and chip scale packages, are provided. The carrier includes a base on which the interconnect is mounted, and a force applying mechanism for biasing the component against the interconnect. The interconnect includes interconnect contacts configured to make temporary electrical connections with component contacts (e.g., bond pads, solder balls). The interconnect also includes support members configured to physically contact the component, to prevent flexure of the component due to pressure exerted by the force applying mechanism. The support members can be formed integrally with the interconnect using an etching process. In addition, the support members can include an elastomeric layer to provide cushioning and to accommodate Z-direction dimensional variations.
