The high-frequency signal transmission line (101) includes a resin layer stack (3) having a first resin layer (11, 12, 13) and a second resin layer (21, 22) stacked thereon, a signal conductor pattern (4) formed on the first resin layer (11), and a ground conductor layer (5) sandwiching part or all of the resin layer stack (3) and opposite to the signal conductor pattern (4). The Young's modulus of the second resin layer (21, 22) is lower than that of the first resin layer (11, 12, 13). An opening is formed in the first resin layer (12) at least along the position of the signal conductor pattern (4) in the resin layer stack (3), thereby providing a hollow portion (HP) in the resin layer stack (3) by means of the opening.

This application relates to a low-power, high-reliability Schottky chip with self-adjusting injection efficiency, belonging to the field of semiconductor processing technology, comprising: a substrate layer, wherein the substrate layer is highly doped with N. + A substrate layer for reducing the on-resistance of the chip; an epitaxial layer disposed on the substrate layer; a Schottky junction region located on the epitaxial layer; and a Speed ​​structure region containing several small P-type transistors. ++ Grid; P + The protective ring, the P + The junction protection rings are located at both ends of the Schottky junction region; N ++ A junction cutoff ring is located at the chip terminal; multilayer passivation regions are used to enhance the product's resistance to high temperature, high humidity, and radiation; front and back metal electrodes are used for electrical connections. This application employs highly doped N... + The substrate layer effectively reduces the on-resistance of the chip, thereby significantly improving the current transmission efficiency.
