Patent ID: 7910385

Claim:
A method for manufacturing microelectronic devices, the method comprising: attaching a plurality of singulated microelectronic dies to a removable support member with an active side of the individual dies contacting the support member, wherein the active sides of the dies include electrical terminals, and individual dies have a first lateral edge and a second lateral edge opposite the first lateral edge; molding a flowable material onto the dies and at least a portion of the removable support member such that the molded material covers a back side of the individual dies and is disposed between adjacent dies; removing the support member from the active sides of the dies; forming redistribution structures, wherein individual redistribution structures are formed at a corresponding die and include conductive links electrically connected to electrical terminals of the corresponding die, ball-pads electrically coupled to the conductive links, and first and second dielectric layers having a peripheral region extending across the molded material outboard from the bond-pads; cutting the molded material, the first dielectric layer and the second dielectric layer between adjacent lateral edges of each neighboring die to singulate the dies, wherein the cut molded material forms individual casings having a peripheral portion extending laterally outward from the dies, wherein the peripheral region of the first and second dielectric layers is supported by the peripheral portion of the casing, and wherein the peripheral region of the first and second dielectric layers extends outboard of the bond-pads from both the first and second opposing lateral edges of each die and outboard of the conductive links of the redistribution structures; and supporting the singulated die with a testing device with a support surface of the testing device contacting only the peripheral region of the second dielectric layer of the singulated die.
