Abstract:
1. A method of manufacturing a microelectronic component assembly, comprising: juxtaposing a back surface of a substrate with an active surface of a microelectronic component, wherein the substrate has a body, a reduced-thickness base portion, and a passage through the base, the body having a first thickness and the base portion having a second thickness that is less than the first thickness, and the active surface of the microelectronic component carries an array of terminals that is accessible through the passage; attaching the back surface of the substrate to the active surface of the microelectronic component with the body of the substrate having a contact surface that is spaced a body height outwardly from the active surface of the microelectronic component; attaching a first bond wire to a first terminal of the array and to a first bond pad carried by the base portion of the substrate, the first bond wire having a maximum height outwardly from the active surface that is less than the body height; attaching a second bond wire to a second terminal of the array and to a second bond pad carried by the base portion of the substrate, the second bond wire having a maximum height outwardly from the active surface that is less than the body height; positioning the substrate in a mold cavity with the contact surface against a lower mold surface of the mold cavity, leaving a first void between the back surface and the upper mold surface and a second void between the active surface and the bottom mold surface; and encapsulating the first and second bonding wires in a dielectric matrix by substantially filling the first and second voids of the mold cavity with the dielectric matrix while the contact surface is urged against the lower mold surface.
