Patent ID: 8623706

Claim:
A method of making a microelectronic package comprising the steps of: (a) positioning a sheet bearing a plurality of traces over an assemblage of a package substrate with conductive elements and a microelectronic element overlying the package substrate and electrically connected to the conductive elements so that portions of at least some of the traces extend over the microelectronic element; (b) introducing a flowable composition between the sheet and the package substrate and around the microelectronic element and curing the composition to form an overmold covering the microelectronic element and having a shape at least partially defined by the sheet; and (c) removing the sheet so as to leave the traces extending over one or more surfaces of the overmold facing away from the package substrate, wherein the step of positioning the sheet includes positioning a first portion of the sheet and first portions of the traces on the first portion of the sheet extending over the microelectronic element and positioning a second portion of the sheet so that the second portion of the sheet and second portions of the traces on the second portion of the sheet extend from the first portion of the sheet toward the package substrate.
