What is the IC Package Substrate Fabrication Process?

The fabrication process of IC package substrates involves several critical steps, each essential to ensuring the performance and reliability of the final product. Here are the main steps in the IC package substrate fabrication process:

1. Material Preparation: Select and prepare appropriate substrate materials such as fiberglass-reinforced epoxy resin (FR-4), polyimide (PI), or ceramics. Materials are typically supplied in thin sheets and need to be cut and processed according to design requirements.
2. Layering and Laminating: Stack different substrate material layers according to the design. The layers are bonded together through heating and pressing using a laminating machine to ensure good adhesion and integrity between the layers.
3. Pattern Transfer: Use photolithography to transfer circuit patterns onto the substrate. A photosensitive coating (photoresist) is applied to the substrate, and then exposed to light through a mask to create the circuit pattern. The unexposed photoresist and excess material are removed through developing and etching processes, forming the circuit pattern on the substrate.
4. Drilling and Plating: Drill holes in the substrate as required by the design, which will be used for electrical connections and mounting. Electroplating is then performed to deposit metal layers on the walls of the holes, creating electrical vias. This step also involves depositing conductive metal layers, such as copper.

6. Pad and Land Fabrication: Create pads and lands on the substrate to provide electrical connections between the IC chip and the substrate. This includes depositing metal pads onto the substrate and surface treatment to improve solder quality.
7. Cutting and Shaping: Cut the fabricated substrate into the required sizes and shapes. This may include cutting large panels into individual substrates or trimming the substrate to specific packaging forms.
8. Testing and Inspection: Perform electrical, mechanical, and thermal performance tests to ensure the substrate meets design specifications and performance requirements. Testing includes functional checks, connectivity verification, and thermal management assessments.
9. Surface Treatment and Coating: Apply surface treatments, such as protective coatings or solder masks, to enhance the durability and reliability of the substrate.
10. Assembly and Packaging: Finally, solder the IC chips onto the substrate and perform final packaging. Packaging steps may include adding package bases, sealing, and testing to ensure integrity and functionality.

Overall, the IC package substrate fabrication process involves material preparation, pattern transfer, drilling, plating, pad fabrication, cutting, testing, and packaging. Each step must be carefully controlled to ensure the quality and performance of the final product.

How Do You Manufacture IC Package Substrate?

Manufacturing IC package substrates involves a series of intricate steps to ensure high performance and reliability. Here’s an overview of the manufacturing process:

1. Material Selection and Preparation: Begin by selecting suitable substrate materials such as fiberglass-reinforced epoxy resin (FR-4), polyimide (PI), or ceramics. The materials are supplied in large sheets, which are cut into the required sizes for further processing.
2. Layering and Laminating: Stack the prepared material layers according to the design specifications. These layers are then laminated together using heat and pressure to create a multi-layer substrate. This step ensures that the layers adhere properly and maintain structural integrity.
3. Photolithography: Apply a photosensitive coating (photoresist) onto the substrate surface. Using photolithography, expose the photoresist to light through a mask that defines the circuit patterns. Develop the exposed photoresist to reveal the pattern, and then etch away the unwanted material to create the circuit design on the substrate.
4. Drilling and Plating: Drill holes in the substrate where electrical connections and vias are required. Electroplating is then used to deposit metal, such as copper, onto the walls of these holes to form electrical connections. This process also involves plating the surface with a thin layer of metal for conductivity.
5. Deposition: Deposit additional thin metal layers onto the substrate surface to enhance electrical performance and ensure good solderability. Techniques such as chemical vapor deposition (CVD) or electroplating are commonly used for this purpose.
6. Pad and Land Formation: Create metal pads and lands on the substrate where IC chips will be soldered. This involves depositing and patterning metal to form the necessary contact points for chip mounting and connection.
7. Cutting and Shaping: Cut the laminated and processed substrate into specific sizes and shapes as required. This may involve dividing large panels into individual substrates or shaping them to fit particular packaging forms.
8. Testing and Inspection: Conduct various tests to ensure that the substrate meets design specifications and performance requirements. This includes electrical testing for continuity and functionality, thermal testing to check heat dissipation, and mechanical testing to ensure structural integrity.
9. Surface Treatment: Apply surface treatments such as solder masks, protective coatings, or finishes to enhance the durability and reliability of the substrate. These treatments help protect the substrate from environmental factors and improve soldering quality.
10. Assembly and Packaging: Solder the IC chips onto the substrate and perform final assembly and packaging. This step includes mounting the chips, sealing the package, and conducting final quality checks to ensure that the substrate is ready for use in electronic devices.
