Abstract: This disclosure discloses a method for preparing an indium pillar, a chip substrate and a chip. The method includes: applying a first photoresist layer on a substrate; applying a second photoresist layer on the first photoresist layer; covering a part of a surface of the second photoresist layer; underexposing the part of the second photoresist layer to obtain a processed second photoresist layer; developing and fixing the processed second photoresist layer to form an undercut structure; etching the first photoresist layer through the undercut structure to form an expose area; and depositing an indium material on the exposed area to form an indium pillar solder.

Abstract: A method for manufacturing an air bridge, an air bridge, and an electronic device are disclosed. The method for manufacturing an air bridge includes: applying a first photoresist layer to a substrate; applying a second photoresist layer to the first photoresist layer; exposing, developing, and fixing the second photoresist layer, to form a patterned structure; etching away the first photoresist layer in a specified area through the patterned structure, to form a structure for blocking a deposition material from diffusing to a periphery on the substrate, the specified area including a projection area formed on the first photoresist layer by a top opening of the patterned structure; and depositing a bridge support structure on a surface of the substrate exposed after the first photoresist layer in the specified area is etched away, and forming an air bridge based on the bridge support structure.
