Semiconductor device with pre-molding chip bonding
View Patent ↗This disclosure relates generally to a semiconductor device and method of making the semiconductor device by pressing an electrical contact of a chip into a bonding layer on a carrier. The bonding layer is cured and coupled, at least in part, to the electrical contact. A molding layer is applied in contact with the chip and a first major surface of the bonding layer. Distribution circuitry is coupled to the electrical contact.
1. A method of making a semiconductor device, comprising:
pressing an electrical contact of a chip into a bonding layer on a carrier;
curing the bonding layer, wherein the bonding layer, as cured, is coupled, at least in part, to the electrical contact;
applying a molding compound in contact with the chip and a first major surface of the bonding layer;
planarizing the bonding layer; then
coupling distribution circuitry to the electrical contact.
2. The method of claim 1 , wherein planarizing the bonding layer includes exposing a contact surface of the electrical contact, and wherein coupling the distribution circuitry couples the distribution circuitry to the contact surface.
3. The method of claim 2 , wherein planarizing the bonding layer includes planarizing the electrical contact to expose the contact surface of the electrical contact.
4. The method of claim 3 :
wherein the chip comprises a plurality of electrical contacts;
wherein pressing the electrical contact comprises pressing the plurality of electrical contacts into the bonding layer; and
wherein planarizing the electrical contact comprises planarizing the plurality of electrical contacts to make contact surfaces of the electrical contacts substantially co-planar.
5. A method of making a semiconductor device, comprising:
pressing an electrical contact of a chip into a bonding layer on a carrier;
curing the bonding layer, wherein the bonding layer, as cured, is coupled, at least in part, to the electrical contact;
applying a molding compound in contact with the chip and a first major surface of the bonding layer;
coupling distribution circuitry to the electrical contact; and
applying a buildup layer on a second major surface of the bonding layer opposite the first major surface and substantially surrounding the distribution circuitry.
6. The method of claim 5 , further comprising coupling solder bumps to the distribution circuitry, wherein the buildup layer secures, in part, the solder bumps.
