Chip interconnection package structure and method

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.

Chip stack packaging structure and chip stack packaging method

A touch control substrate, a preparation method thereof, a touch control module, and a display device are provided. The touch control substrate comprises: a substrate, a conductive functional layer, and a second protection medium. The conductive functional layer is arranged on one side of the substrate, and comprises patterned nano conductive structure, first protection medium, and frame lead structure. The conductive functional layer is protected by providing a two-layer protection medium structure, wherein the first protection medium fixes the structural position of the nano conductive layer and protects the partial structure of the conductive functional layer, and the second protection medium at least completely covers the nano conductive layer located in the conductive functional area; and at the same time, the touch control substrate directly disposes the frame lead layer in the peripheral area of the nano conductive layer, making the frame lead directly contacting the nano conductive layer.
