A method for testing TSVs is provided. A plurality of TSVs is formed in a semiconductor substrate. Wiring layers and a first contact array are formed on the front-side of the substrate. The wiring layers couple each of the TSVs to a respective contact of the first contact array. Conductive adhesive is deposited over the first contact array. The conductive adhesive electrically couples contacts of the first contact array. A carrier is bonded to the front-side of the substrate with the conductive adhesive. After bonding the carrier to the substrate, the back-side of the substrate is thinned to expose each of the TSVs on the back-side of the substrate. A second contact array is formed, having a contact coupled to each respective TSV. Conductivity and connections of the TSVs, wiring layers, and contacts are tested by testing for conductivity between contacts of the second contact array.

In one embodiment, a method of forming a multi-die semiconductor device is provided. A plurality of dice is mounted on a semiconductor substrate, and neighboring ones of the dice are separated by a distance at which a first one of the neighboring dice will contact a meniscus of a flange of the neighboring die during underfill to form a capillary bridge between the neighboring dice. Solder bumps are reflowed to electrically connect contact terminals of the plurality of dice to contact terminals on a top surface of the substrate. Underfill is deposited along one or more edges of one or more of the plurality of dice. As a result of the capillary bridge formed between neighboring dice, flow of underfill is induced between the bottom surfaces of the neighboring dice and the top surface of the substrate. The dispensed underfill is cured.
