A photoresist material is applied to the substrate, exposed to UV light through a photomask, and developed to create a patterned resist layer. This pattern is then transferred to the underlying thin films using etching processes.
- **Etching**: Etching processes, such as wet etching or dry etching (plasma etching), are used to selectively remove material from the substrate surface based on the pattern defined by the photoresist. This step creates the desired circuit traces, vias, and other features on the substrate.
- **Via Formation**: Vias, which are small holes drilled or etched through the substrate, are created to provide electrical connections between different layers of the substrate or to connect components on opposite sides. Laser drilling or chemical etching may be used to create vias with precise dimensions.
- **Metalization**:Metal layers, typically consisting of copper or other conductive metals, are deposited onto the substrate surface to create conductive traces, pads, and interconnects. Metalization may involve processes like electroplating, electroless plating, or thin film deposition.
- **Surface Finish**: Surface finish processes are applied to the substrate to improve solderability, corrosion resistance, and electrical performance. Common surface finishes include electroless nickel immersion gold (ENIG), immersion silver, and organic surface coatings.
- **Inspection and Testing**: The fabricated substrate undergoes inspection and testing to ensure that it meets the specified dimensional tolerances, electrical properties, and quality standards. Various techniques, including optical inspection, electrical testing, and dimensional measurement, may be used for quality control.
- **Packaging and Assembly**: Once fabricated, the substrate is ready for packaging and assembly into electronic devices. Components such as integrated circuits (ICs), transistors, capacitors, and resistors are mounted onto the substrate using soldering or bonding techniques, and the assembly may undergo additional testing and inspection before final integration into the end product.
By following these fabrication steps, engineers can produce RF High Frequency package substrates with precise electrical characteristics, low signal loss, and excellent mechanical reliability, meeting the demanding requirements of high-frequency electronic systems.
