Abstract

The invention discloses a metal dielectric layer, a manufacturing method thereof and a circuit board. The circuit board structurally comprises a substrate, at least one bonding pad and at least one circuit component. The circuit component is connected with other circuits through the bonding pad. The bonding pad comprises a first conducting layer, a second conducting layer, wire pressing points and the metal dielectric layer. The wire pressing points are arranged on the upper surface of the second conducting layer. The metal dielectric layer is located between the first conducting layer and the second conducting layer. The metal dielectric layer comprises a first dielectric layer, a first spin-coating glass layer and a second dielectric layer. The first dielectric layer is arranged on the upper surface of the first conducting layer. The first spin-coating glass layer is arranged on the upper surface of the first dielectric layer. The first spin-coating glass layer is the spin-coating glass layer containing arsenic. The second dielectric layer is located on the upper surface of the first spin-coating glass layer.

Description

technical field [0001] The present application relates to the technical field of semiconductors, in particular to a metal dielectric layer, a manufacturing method thereof, and a circuit board. Background technique [0002] With the rapid development of semiconductor technology, especially with the development of integrated circuits, the requirements for integrated circuits are becoming increasingly sophisticated and complex. In order to reduce costs, the current common integrated circuit packaging method is COB (chip on board: chip on board packaging), which is to adhere the bare chip to the interconnection substrate with conductive or non-conductive adhesive, and then perform wire bonding to realize its electrical connection. connect. In the COB packaging process, the key technology lies in wire bonding (Wire Bonding). Wire bonding refers to the use of aluminum wire bonding machines to connect the chip (LED die or IC chip) to the corresponding PCB board (printed circuit bo...
