3. Photoresist Application: A photoresist layer is applied to the substrate surface. This layer is sensitive to UV light, allowing for patterning.
4. Exposure and Development:The photoresist is exposed to UV light through a photomask, which defines the circuit pattern. The exposed areas are then developed, removing the photoresist to reveal the underlying substrate.
5. Etching: Chemical etching or laser etching is used to remove unwanted material, creating the desired circuit pathways. This step is crucial for defining trace widths and spacing.
6. Via Formation: Microvias are created using laser drilling or mechanical drilling techniques. These vias facilitate vertical connections between layers.
7. Metal Deposition: A thin layer of metal (commonly copper) is deposited onto the substrate using methods like electroplating or sputtering. This metal layer forms the conductive traces.
8. Surface Treatment: The substrate may undergo surface treatments to enhance adhesion and prepare for the next layer of photoresist or solder mask.
9. Solder Mask Application: A solder mask is applied to protect the circuit traces and prevent solder from bridging during assembly. This is typically applied as a liquid and cured to form a solid layer.
10. Final Inspection: The substrate undergoes thorough inspection for defects, ensuring it meets the required specifications before moving on to assembly.
11. Assembly: The ultrathin substrates are populated with ICs and other components, typically using automated pick-and-place systems, followed by soldering processes such as reflow soldering.
12. Testing: Final electrical testing is performed to ensure functionality and reliability, checking for signal integrity and thermal performance.

This meticulous fabrication process enables the production of high-density, high-performance ultrathin IC/BGA substrates suitable for various advanced electronic applications.
