Package structure for low cost and ultra thin chip scale package

Thin organic layers are laminated on both the top and bottom of a relatively thin ceramic layer to form a reliable thinner composite substrate for packaging a chip-scale flip-chip die in a thin package.

Zusammenfassung:Thin organic layers are laminated on both the top and bottom of a relatively thin ceramic layer to form a reliable thinner composite substrate for packaging a chip-scale flip-chip die in a thin package. A semiconductor die has a number of solder bump-mounting pads formed thereupon which are connected with solder bumps to mounting pads on the top surface of the thin composite substrate.
