3. Photoresist Application: A photoresist layer is applied to the substrate surface. This light-sensitive material will define the areas to be etched away or left intact. The photoresist is typically applied using spin coating.
4. Patterning: The photoresist-coated substrate is exposed to ultraviolet (UV) light through a photomask that defines the desired pattern of traces and pads. The exposed photoresist is then developed to reveal the pattern that will be etched into the substrate.
5. Etching: The exposed areas of the substrate are etched away using chemical etchants or plasma etching, creating the necessary traces, pads, and vias. This step defines the electrical pathways and bond pads on the substrate.
6. Deposition of Metal Layers: Thin metal layers, such as copper, gold, or nickel, are deposited onto the substrate using techniques like sputtering or electroplating. These metals form the electrical traces, bond pads, and other conductive features necessary for wire bonding.
7. Photoresist Removal: The remaining photoresist is stripped away, leaving behind the patterned metal layers on the substrate.
8. Via Formation: Vias, or vertical interconnects, are created by drilling or etching holes through the substrate layers. These vias are then filled with metal to establish electrical connections between different layers of the substrate.
9. Solder Mask Application: A solder mask is applied to protect the metal traces and bond pads from soldering and environmental damage. The solder mask also defines the areas where solder will be applied.
10. Final Testing and Inspection:The fabricated substrate undergoes rigorous testing and inspection to ensure it meets design specifications and quality standards. This includes checking for electrical continuity, mechanical integrity, and adherence to design rules.
11. Dicing and Packaging: The completed substrates are diced into individual units, each ready for chip mounting and wire bonding. The substrates are then packaged and prepared for integration into electronic devices.

The Wire Bonding Chip Scale Package Substrates fabrication process combines precision engineering and advanced materials science to produce high-performance substrates suited for compact and efficient semiconductor packaging.
