Techniques for manufacturing a circuit board having a countersunk via

A technique for manufacturing a circuit board involves obtaining a plane-shaped structure having layers of circuit board material integrated together, and carving a hole within the plane-shaped structure (e.g., using a single countersinking drill bit). The carved hole includes an inner portion having a substantially uniform inner portion diameter and a connecting portion disposed between the inner portion and an outer surface of the plane-shaped structure. At least part of the connecting portion has a diameter which is larger than the substantially uniform inner portion diameter of the inner portion to improve access to the inner portion. The technique further involvesperforming a plating process on the plane-shaped structure to provide plating over the hole carved within the plane-shaped structure. The provided plating forms a countersunk via which provides an electrical pathway from the outer surface of the plane-shaped structure to an internal circuit board trace.

Three dimensional integrated circuit

Implanting ions to form a cleave layer in a semiconductor device causes damage to sensitive materials such as high-K dielectrics. In a process for forming a cleave layer and repairing damage caused byion implantation, ions are implanted through a circuit layer of a substrate to form a cleave plane. The substrate is exposed to a hydrogen gas mixture for a first time at a first temperature to repair damage caused by the implanted ions. A cleaving process may then be performed, and the cleaved substrate may be stacked in a 3DIC structure. A stacked device is formed by bonding a die to a first substrate, the die having a smaller width than a width of the first substrate, depositing a planarization material over the die, planarizing the planarization material to form a planarized upper surface, and stacking a third substrate on the planarized upper surface.
