    摘要: Described herein are IC devices include vias deposited in a regular array, e.g., a hexagonal array, and processes for depositing vias in a regular array. The process includes depositing a guiding pattern over a metal grating, depositing a diblock copolymer over the guiding pattern, and causing the diblock copolymer to self-assemble such one polymer forms an array of cylinders over metal portions of the metal grating. The polymer layer can be converted into a hard mask layer, with one hard mask material forming the cylinders, and a different hard mask material surrounding the cylinders. A cylinder can be selectively etched, and a via material deposited in the cylindrical hole to form a via.

    摘要: Hyperchip structures and methods of fabricating hyperchips are described. In an example, an integrated circuit assembly includes a first integrated circuit chip having a device side opposite a backside. The device side includes a plurality of transistor devices and a plurality of device side contact points. The backside includes a plurality of backside contacts. A second integrated circuit chip includes a device side having a plurality of device contact points thereon. The second integrated circuit chip is on the first integrated circuit chip in a device side to device side configuration. Ones of the plurality of device contact points of the second integrated circuit chip are coupled to ones of the plurality of device contact points of the first integrated circuit chip. The second integrated circuit chip is smaller than the first integrated circuit chip from a plan view perspective.
