Abstract

The invention provides a chip with a composite layer and application of the chip in biological detection. The chip comprises at least a first base layer and a second base layer which are arranged along a vertical direction, wherein at least one first blind hole leading to the second base layer is formed in the first base layer, at least one metallized via hole penetrating through the second base layer is formed in the chip, an electrode is arranged below the first blind hole, the chip is provided with a contact, and the electrode is connected with the contact through a circuit. According to the invention, plastic and metal are combined to develop the chip with the composite layer, the basic functions of the chip are realized through reasonable layout of the base layer, a circuit layer andan internal circuit of the chip, and the chip is simple to manufacture and low in cost.

Description

technical field [0001] The invention belongs to the technical field of chips, in particular to a chip with a composite layer and its application in biological detection. Background technique [0002] With the rapid development of electronics and information technology, our country has entered the information age. As a micro-integrated circuit, chips are widely used in various electronic products and systems such as computers, mobile phones, home appliances, automobiles, high-speed rail, power grids, medical instruments, robots, and industrial controls. They are the core cornerstone of high-end manufacturing. The chip is composed of a base layer and a circuit. The base layer is made of a single crystal silicon wafer, and is made of a metal-oxide semiconductor field-effect transistor (MOSFET) or a bipolar transistor by photolithography, doping, and chemical mechanical polishing (CMP). Components such as transistors (BJT), and then use thin film and CMP technology to make circ...
