Abstract:
A method of making a microelectronic package, comprising:(a) making at least one microelectronic component, comprising the steps of:(i) embossing a metal layer having a first face and a second face by engaging said metal layer between a pair of forming elements and deforming said metal layer by engagement with said forming elements so as to form thick and thin regions of metal in said metal layer;(ii) removing metal from said thick and thin regions of metal in said metal layer by a removal process which nonselectively removes metal from at least one face of said metal layer; and(iii) arresting said removal process after said thin regions of metal have been removed but prior to removal of said thick regions of said metal layer so that said thick regions of metal remain as first metallic elements; and(b) assembling each of said at least one microelectronic component with at least one microelectronic element.
