PACKAGED MULTICHIP DEVICE WITH STACKED DIE HAVING A METAL DIE ATTACH
A leadless multichip semiconductor device includes a metal substrate having a through-hole aperture with an outer ring for holding a bottom semiconductor die with an inner row and an outer row of metal pads. The bottom semiconductor die has a back side metal (BSM) layer on its bottom side and a top side with bond pads mounted top side up on the ring. A metal die attach layer is directly between the BSM layer and walls of the metal substrate providing a die attachment that fills a bottom portion of the aperture. Bond wires are between the inner metal pads and the bond pads. A top semiconductor die has top bond pads mounted top side up on a dielectric adhesive on the bottom semiconductor die. Pins connect the top bond pads to the outer metal pads. A mold compound provides isolation between adjacent ones of the metal pads.
