Abstract:
A method of making a semiconductor chip package, said method comprising the steps of:I. providing a dielectric layer having at least one microelectronic element disposed thereon;II. placing the dielectric layer into a mold;III. sealingly engaging the mold with the dielectric layer;IV. shearing a thixotropic composition having an initial viscosity to reduce its viscosity;V. disposing the sheared thixotropic composition into the mold such that the area between the at least one microelectronic element and the dielectric layer is filled;VI. waiting for a period of time sufficient to allow the sheared thixotropic composition to regain at least a portion of its initial viscosity;VII. then, removing the dielectric layer from the mold; andVIII. curing the sheared thixotropic composition to form a cured encapsulant.
