What is the Fabrication Process for Ajinomoto (ABF) Flip Chip Substrate?

The fabrication process for Ajinomoto Build-up Film (ABF) Flip Chip Substrate involves several critical steps to create high-performance and reliable substrates for advanced semiconductor packaging. Here’s an overview of the process:

1. Substrate Preparation: Start with a base material, typically a thin copper foil or a pre-laminated core. This forms the foundation for the ABF build-up layers. The base material is cleaned and treated to ensure proper adhesion of subsequent layers.
2. Build-Up Layer Application: Apply a build-up film (ABF) to the base material. This film is a polymer resin with high performance in terms of electrical and thermal properties. The ABF film is laminated onto the base material using heat and pressure.
3. Photoimaging and Etching: Once the build-up layer is applied, it is subjected to photolithography. A photoresist layer is coated on top, and the desired circuit patterns are exposed using ultraviolet (UV) light. The exposed areas are developed and then etched away to form the necessary circuit patterns and vias.
4. Via Formation: For multi-layer substrates, vertical interconnections (vias) are created to connect different layers of the substrate. This involves drilling or laser ablation to form vias, followed by plating with copper to establish electrical connections between layers.
5. Layer-by-Layer Build-Up: Additional layers of ABF film are sequentially added, and the photoimaging and etching processes are repeated. Each layer is carefully aligned and bonded to the previous layer to build up the substrate to the required thickness and complexity.
6. Pad Formation and Plating: Solder pads and other interconnect features are formed on the surface of the substrate. This is done by depositing and patterning copper on the substrate, followed by electroplating to enhance pad thickness and improve solderability.
7. Chemical Mechanical Planarization (CMP): The surface of the substrate is polished to achieve a smooth and even finish. CMP removes any excess material and ensures that the surface is flat and ready for further processing.
8. Final Inspection and Testing: The substrate undergoes rigorous inspection and testing to ensure it meets quality standards. This includes checking for defects, verifying electrical performance, and ensuring dimensional accuracy.
9. Dicing and Packaging: Once the substrate has passed inspection, it is diced into individual units if required. The final substrates are then packaged for shipment or further assembly into electronic devices.
10. Reflow and Assembly: If the substrate is being used for flip chip packaging, the chip is aligned and attached to the substrate using solder bumps. The assembly is then subjected to a reflow process to melt the solder and form strong electrical connections between the chip and the substrate.

This fabrication process ensures that Ajinomoto ABF Flip Chip Substrates meet the high standards required for advanced semiconductor applications, providing excellent electrical performance, thermal management, and reliability.

3. Lamination of ABF Film:Apply the ABF film to the base substrate using a lamination process. The film is positioned on the substrate and then subjected to heat and pressure to bond the film firmly to the base material.
4. Photoresist Coating and Patterning: A photoresist layer is applied over the ABF film. This layer will be patterned to create the circuit design. The photoresist is exposed to UV light through a mask that defines the desired circuit patterns. The exposed photoresist is then developed to reveal the pattern.
5. Etching: After patterning, the substrate is subjected to an etching process to remove the unprotected ABF material. This creates the circuit traces and via openings according to the design.
6. Via Formation: For multi-layer designs, vias are formed to create electrical connections between different layers. This involves drilling or laser ablation to form via holes, followed by plating with copper to establish electrical continuity.
7. Build-Up Layer Addition: Additional layers of ABF film are applied and processed similarly to the initial layer. This build-up process is repeated as necessary to achieve the required number of layers and circuit complexity.
8. Pad Formation and Plating: Solder pads and other interconnect features are formed by depositing and patterning copper on the surface of the substrate. Electroplating is used to enhance the thickness and solderability of these pads.
9. Chemical Mechanical Planarization (CMP): The substrate’s surface is polished using CMP to ensure a smooth and flat surface. This step removes excess material and ensures that the surface is suitable for the final assembly.
10. Inspection and Testing: Conduct thorough inspection and testing of the substrate to ensure it meets quality standards. This includes checking for defects, verifying circuit integrity, and ensuring the substrate meets dimensional and performance specifications.
11. Dicing and Packaging:After passing inspection, the substrate is diced into individual units if required. The final products are packaged for shipment or further assembly into electronic devices.
