摘要: The bond strength between a semiconductor chip and a metal heat sink in an integrated circuit package can be improved by using an adhesive system comprising two separate layers, one layer exhibiting preferential bonding strength for the chip and the other layer exhibiting preferential bonding strength for the metal heat sink.

摘要: A chip package includes a die having an active surface and an inactive surface. An adhesive is formed on the inactive surface where the adhesive has a low Young's modulus of elasticity. The low Young's modulus of elasticity may be 10,000 psi or less; 1,000 psi or less; or, preferably, about 1,000 psi. Further, the adhesive may include a thermal conducting material. A protective plate is coupled to the inactive surface using the adhesive and a chip carrier is coupled to the active surface of the die.
