What is thick-film integrated circuit, the basic structure of thick-film integrated circuit, thick-film materials, characteristics, working principles, main processes, applications, and testing methods 1

Thick-film integrated circuits (THIC) are a novel type of integrated circuit technology that utilizes thick-film materials as the substrate for circuits, directly forming circuit components and interconnects on the thick film to achieve circuit integration. Compared to traditional thin-film integrated circuits, thick-film integrated circuits offer higher reliability, lower manufacturing costs, and broader application scope.  diode,

1. Basic Structure:

The basic structure of thick-film integrated circuits consists of two parts: circuit components and circuit interconnections. The circuit components include resistors, capacitors, inductors, diodes, transistors, and others, which are formed on the circuit substrate through thick-film materials. The circuit interconnections connect these components to form a complete circuit.

II. Thick Film Materials:

Commonly used thick-film materials include ceramics, glass, and quartz. These materials possess excellent insulation properties, high-temperature resistance, and mechanical strength, meeting the requirements of circuit applications.

III. Features:

1. Low Cost: Compared to other integrated circuit manufacturing technologies, thick-film integrated circuits have lower production costs, primarily due to the relatively low price of materials used and a simpler manufacturing process.

2. High Reliability: The sintering process and lower sintering temperatures in thick-film integrated circuit manufacturing do not impose significant thermal stress on the device and circuit structure, thereby enhancing circuit reliability.

3. Good stability: Thick-film materials exhibit excellent chemical and thermal stability, enabling operation under harsh environmental conditions. diode

4. Simple Manufacturing Process: Compared to other integrated circuit manufacturing technologies, the production process of thick-film integrated circuits is relatively straightforward, requiring neither complex photolithography nor high-temperature manufacturing techniques.
