METHOD AND APPARATUS FOR CREATING A BOND BETWEEN OBJECTS BASED ON FORMATION OF INTER-DIFFUSION LAYERS

摘要

The present disclosure provides a method of creating a bond between a first object and a second object. For example, creating a joint or die attach between a semiconductor chip and an electronic substrate, especially for harsh and high temperature environments. The method may include a step of filling a space between the first object and the second object with a filler material. Further, the method may include a step of heating the filler material to facilitate formation of a plurality of inter-diffusion layers. Accordingly, a first inter-diffusion layer may be formed between the filler material and the first object. Further, a second inter-diffusion layer may be formed between the filler material and the second object. Furthermore, in some embodiments, the first inter-diffusion layer may be contiguous with the second inter-diffusion layer. The contiguity may be facilitated by placement of at least one insert between the first object and the second object, in which the inter-diffusion of the filler material and the at least one insert may produce the third inter-diffusion layer, wherein the third inter-diffusion layer is contiguous with each of the first inter-diffusion layer and the second inter-diffusion layer.
