  • Publication number: 20230299060
    Abstract: 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 by ion 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.

  • Patent number: 10923359
    Abstract: Processes for the localized etching of films on the sidewalls of non-planar 3D features such as a trench or a FinFET array. The etch process has a first step of an angle-directed ion implant beam, with the beam being self-aligned onto a localized region on a sidewall feature, that functionalizes the region for a second step that etches the ion implanted region.

  • Publication number: 20180175008
    Abstract: A device is formed by providing a first substrate, depositing a thickness of range compensating material on a first surface of the first substrate, implanting ions into the first substrate, the ions traveling through the range compensating material to define a cleave profile in the first substrate, the cleave profile including a contour that corresponds to the thickness of absorber material, removing the absorber material, and cleaving the first substrate at the cleave profile, thereby exposing the contour. A substrate with high thermal conductivity in which the contour defines a coolant channel effectively removes heat from a three-dimensional integrated circuit.
