Abstract
A semiconductor device including a thin coupon capacitor mounted to the backside of a semiconductor die. When mounted active surface up on a carrier substrate of a multi-chip module, the coupon is secured between the backside of the die and the substrate. When flip-chip connections or direct chip attach are employed between the die and substrate, the coupon is secured to the backside of the die. The coupons may be preformed, or formed on the die in a wafer-scale fabrication process prior to singulation of the dice.
