Abstract:
1. A method comprising: providing a first substrate having a first plurality of electrical connections formed thereon; applying a first material to the first plurality of electrical connections to between about one-half and less than a full height of each of the first plurality of electrical connections; providing a second substrate having a second plurality of electrical connections formed thereon; contacting the first plurality of electrical connections of the first substrate to corresponding ones of the second plurality of electrical connections of the second substrate; and performing a reflow process on the first plurality of electrical connections and the second plurality of electrical connections to form a third plurality of electrical connections between the first substrate and the second substrate, wherein the first material encapsulates a portion of each of the third plurality of electrical connections, and wherein a widest lateral extent of the first material encapsulating the portion of each of the third plurality of electrical connections is greater than a widest lateral extent of each of the second plurality of electrical connections.
