A method of forming a chip assembly, the method comprising:
- forming a plurality of cavities in a carrier;
- arranging a die attach liquid in each of the cavities;
- arranging a plurality of chips on the die attach liquid, each chip comprising a rear side metallization and a rear side interconnect material disposed over the rear side metallization, wherein the rear side interconnect material faces the carrier;
- evaporating the die attach liquid;
- and
- after the evaporating the die attach liquid, fixing the plurality of chips to the carrier.
A method of forming a chip assembly, the method comprising:
- forming a plurality of cavities in a carrier;
- disposing a carrier interconnect material over a bottom of each of the cavities;
- arranging a die attach liquid in each of the cavities;
- arranging a plurality of chips on the die attach liquid, each chip comprising a rear side metallization;
- evaporating the die attach liquid;
- and
- after the evaporating the die attach liquid, fixing the plurality of chips to the carrier.
A chip assembly, comprising:
- a carrier with a top side comprising a plurality of cavities formed in the top side of the carrier, each cavity configured to receive a chip;
- a plurality of chips, each chip being arranged in an associated cavity of the plurality of cavities, and each chip comprising a chip contact being fixed to the bottom of the associated cavity;
- wherein the top side of the carrier outside the cavities is not flush with the plurality of chips.
