A semiconductor component includes a thinned semiconductor die having protective
polymer layers on up to six surfaces. The component also includes contact bumps
on the die embedded in a circuit side polymer layer, and terminal contacts on the
contact bumps in a dense area array. A method for fabricating the component includes
the steps of providing a substrate containing multiple dice, forming trenches on
the substrate proximate to peripheral edges of the dice, and depositing a polymer
material into the trenches. In addition, the method includes the steps of planarizing
the back side of the substrate to contact the polymer filled trenches, and cutting
through the polymer trenches to singulate the components from the substrate. Prior
to the singulating step the components can be tested and burned-in while they remain
on the substrate.
