  • Publication number: 20240186254
    Abstract: Disclosed are a method for manufacturing a carrier structure suitable for chiplet fine lines and a carrier structure. The method includes: preparing a temporary bonding layer on a temporary carrier, and preparing a pin interconnection layer on the temporary bonding layer, preparing at least one fine line interconnection layer on the pin interconnection layer; preparing a core layer on the at least one fine line interconnection layer with a second electrically conductive structure interconnected with the at least one fine line interconnection layer and/or the pin interconnection layer, preparing at least one build-up layer connected to the fine line interconnection layer on the core layer, and de-bonding the temporary bonding layer to obtain the carrier structure. The solutions can prepare fine lines on a carrier structure and ensure the yield of fine line interconnection lines, thus improving the manufacturability of the fine lines, carrier structure and packaging structure.

  • Patent number: 11869872
    Abstract: A chip stack packaging structure and method includes: a base chip layer, including a base chip with pins on the front surface; at least one stacked chip layer, which is formed on the base chip layer, has an inter-chip insulating layer and at least one stacked chip attached to the insulating layer and pins on the front surface, where the front surface of the stacked chip faces the front surface of the base chip; and a top insulating layer, stacked on the stacked chip layer farthest from the base chip layer. A vertical interconnection hole is formed inside the inter-chip insulating layer to allow the corresponding pins to be communicated vertically so as to be electrically connected. Inside the vertical interconnection hole, a conductive material layer is formed that makes the corresponding pins electrically connected; the stacked chip is thinned and reduced after being attached to the inter-chip insulating layer.
