In a method for mounting a sheet-like microelectronic element, the sheet-like element comprises a dielectric layer having a top surface and a bottom surface and is first bonded to an expansion ring. The expansion ring is then heated to stretch the sheet-like element. A frame ring, having an external diameter smaller than the internal diameter of the expansion ring, is then bonded to the sheet-like element. A plurality of leads are formed on the bottom surface of the sheet-like element, the leads including bonding pads. In other embodiments, a method is provided for bonding bond pads on a sheet-like microelectronic element to contacts on a microelectronic component. |
