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.
