摘要:
A method of making a semiconductor chip package by attaching a chip to a dielectric layer; placing the dielectric layer and chip into a mold; disposing a thixotropic composition that has bee sheared to reduced its viscosity into the mold and curing the thixotropic composition after the chip and dielectric layer have been removed from the mold. A method of making a semiconductor chip package without using a mold by disposing a sheared thixotropic composition between a semiconductor chip and a dielectric layer and then curing the thixotropic composition to form a cured encapsulant. A method of making a semiconductor chip package without using a mold during the curing step and without the need to use a thixotropic composition by placing a semiconductor chip attached to a dielectric layer into a mold and disposing a liquid composition between the chip and the dielectric layer, forming a cured skin on the liquid composition, removing the work-piece from the mold and then completely the cure of the liquid composition.
