Abstract:
PROBLEM TO BE SOLVED: To provide a chip package that has improved heat radiation properties, and can reduce costs and thickness and improve heat-resistant stress. SOLUTION: The chip package comprises: a thin-film substrate 210 that has a groove 211, and comprises a pattern metal core layer 212 and surface dielectric layers 215, 216, where a plurality of internal fingers 213 and a plurality of pads 214 for circumscription are formed on the pattern metal core layer 212, and the internal finger 213 is arranged at the periphery of the groove 211; a chip 220 for forming a plurality of electrode edges 223 on an active surface 221, and adhering the active surface 221 to the thin-film substrate 210 when the electrode edges 223 are arranged toward the inside of the groove 211; a plurality of bonding wires 230 that are passed through the groove 211 and connect the electrode edge 223 and the internal finger 213 electrically; and a sealing body 240 that is formed on the thin-film substrate 210 and in the groove 211, and seals the chip 220 and the bonding wire 230.

Abstract:
PROBLEM TO BE SOLVED: To provide a chip lamination method for inhibiting separation between chips. SOLUTION: A substrate having multiple connecting pads is formed (step 1), and then, a first chip is set on the substrate (step 2). The first chip has a plurality of first bonding pads located on an active surface, and the first bonding pad and the substrate's connection pads are electrically connected (step 3). A liquid die attaching material is printed on the first active surface (step 4), and a defoaming operation will exclude minute air bubbles in the liquid die attaching material (step 5). After a primary annealing, the liquid die attaching material becomes half-cured and is formed into a compact adherent intermediary layer (step 6). A second chip is stacked to the first chip, and the compact adherent intermediary layer is used to stick the rear of the second chip that has multiple second bonding pads located on the active surface (step 7). A secondary annealing operation is carried out to cure up the compact adhesive intermediary layer. COPYRIGHT: (C)2007,JPO&INPIT
