Abstract:
An integrated circuit device comprising:an integrated circuit assembly including(a) a memory circuit die made with a memory circuit fabrication process, said memory circuit die having(i) a first plurality of conductive contacts arranged on a first connecting side of said memory circuit die; and(ii) a memory circuit formed on said memory circuit die and electrically coupled to said first plurality of conductive contacts; and(b) a logic circuit die made with a logic circuit fabrication process, said memory circuit die and said logic circuit die being attached together, said logic circuit die having(i) a second plurality of conductive contacts arranged on a second connecting side of said logic circuit die; and(ii) a logic circuit formed on said logic circuit die and electrically coupled to said second plurality of connecting contacts;wherein said memory circuit die and said logic circuit die are attached together in a flip-chip fashion with said first connecting side in close proximity to said second connecting side and with said first plurality of conductive contacts connected to said second plurality of contacts to provide electrical connections between said memory circuit and said logic circuit, thereby forming a unitary, integrated circuit assembly.
