What is the Fabrication Process for Showa Denko Substrate?

The fabrication process for Showa Denko substrates involves several key steps to achieve the desired material properties and dimensional precision required for electronic packaging applications. Here’s an overview of the typical fabrication process:

1. Raw Material Preparation: The process begins with the selection of high-quality raw materials, typically aluminum nitride (AlN) or silicon nitride (Si3N4), known for their high thermal conductivity and electrical insulation properties. These materials are sourced and prepared according to strict quality standards.
2. Powder Mixing and Forming: The raw materials undergo a powder mixing process to achieve a homogeneous blend. The mixed powder is then formed into green sheets or tapes using tape casting or extrusion methods. This step is crucial for achieving the desired substrate thickness and uniformity.
3. Green Sheet Cutting and Stacking: The green sheets are cut into precise dimensions and stacked layer by layer to build the substrate structure. Each layer may contain vias or patterns for electrical connections and thermal management.
4. Lamination and Deburring: The stacked green sheets undergo lamination under controlled pressure and temperature to bond them together. After lamination, any excess material or burrs are removed through deburring processes to ensure smooth edges and precise dimensions.
5. Firing (Sintering): The stacked and laminated substrate undergoes a high-temperature firing process, also known as sintering. During sintering, the substrate is heated to temperatures above the melting point of the binder materials used in the green sheets. This process removes the binder and densifies the ceramic material, resulting in a solid, high-density substrate with the desired mechanical and thermal properties.
6. Surface Finishing: After sintering, the substrate surfaces are prepared for subsequent metallization and assembly processes. This may involve polishing or grinding to achieve smooth and flat surfaces suitable for bonding with semiconductor devices.
7. Metallization: Metallization layers are applied to the substrate surfaces using techniques such as sputtering or plating. These metallization layers serve as conductive paths for electrical connections and may also enhance thermal conductivity in specific areas of the substrate.
8. Quality Control and Testing: Throughout the fabrication process, stringent quality control measures are implemented to ensure the substrates meet specifications for dimensional accuracy, material purity, electrical insulation, thermal conductivity, and mechanical strength. Various tests, including dimensional inspection, electrical testing, and thermal performance testing, are conducted to validate substrate quality.
9. Packaging and Shipping: Once fabricated and tested, Showa Denko substrates are packaged according to industry standards to protect them during transportation and storage, ensuring they arrive at the customer’s facility in optimal condition for semiconductor assembly.

By following these fabrication steps with precision and attention to detail, Showa Denko produces substrates that meet the demanding requirements of modern electronic devices, particularly in applications where thermal management and reliability are critical factors.

How do you Manufacture a Showa Denko Substrate?

Manufacturing a Showa Denko substrate involves a series of detailed processes to ensure the material’s high thermal conductivity and electrical insulation properties meet stringent electronic packaging standards. Here’s a step-by-step outline of how Showa Denko substrates are typically manufactured:

1. Material Selection: High-quality raw materials are selected, primarily aluminum nitride (AlN) or silicon nitride (Si3N4), chosen for their excellent thermal conductivity and electrical insulation characteristics.
2. Powder Preparation: The selected raw materials undergo rigorous preparation processes, including milling and blending, to achieve a uniform particle size distribution and consistent material properties.
3. Forming Green Sheets: The prepared powders are mixed with binders and solvents to form a slurry. This slurry is then cast into thin sheets or tapes using tape casting or extrusion methods. These green sheets contain the ceramic material and binders needed for subsequent processing.
4. Cutting and Stacking:The green sheets are cut into precise dimensions and stacked layer by layer according to the substrate design specifications. Each layer may include features such as vias, patterns, and cavities for electrical interconnects and thermal management.
5. Lamination:The stacked green sheets undergo lamination under controlled pressure and temperature conditions. Lamination bonds the layers together while simultaneously removing most of the solvent and some of the binder from the green sheets.
6. Debinding: After lamination, the substrate undergoes a debinding process to remove the remaining organic binders and solvents. This step is crucial to prevent residual carbon and ensure the substrate achieves the desired purity and density during sintering.
7. Sintering: The debound substrate is then fired in a high-temperature furnace in a process known as sintering. During sintering, the ceramic particles fuse together, densifying the substrate and eliminating porosity. This step significantly enhances the substrate’s mechanical strength, thermal conductivity, and electrical insulation properties.
8. Surface Finishing: Post-sintering, the substrate surfaces may undergo additional processing steps such as polishing, grinding, or chemical mechanical planarization (CMP) to achieve smooth, flat surfaces essential for subsequent metallization and semiconductor device bonding.
9. Metallization: Metallization layers are deposited onto the substrate surfaces using techniques like sputtering, evaporation, or plating. These metallization layers serve as conductive paths for electrical connections and may also enhance thermal conductivity in specific regions of the substrate.
10. Quality Assurance: Throughout the manufacturing process, rigorous quality control measures are implemented to ensure each substrate meets stringent specifications for dimensional accuracy, material purity, electrical properties, thermal performance, and mechanical integrity. Various tests, including dimensional inspection, electrical testing, thermal conductivity measurement, and reliability testing, are conducted to validate substrate quality.
11. Packaging and Delivery:Once manufactured and tested, Showa Denko substrates are carefully packaged to protect them during transportation and storage. They are then shipped to semiconductor manufacturers and assembly facilities for integration into electronic devices.

By meticulously following these manufacturing steps, Showa Denko ensures that its substrates provide superior performance and reliability in electronic packaging applications, particularly in industries requiring efficient thermal management and high reliability, such as power electronics, RF devices, and LED modules.

3. Complexity of Design: Substrates with intricate designs, multiple layers, specific patterns (such as vias and cavities), and precise dimensional requirements may incur higher manufacturing costs.
4. Surface Finish and Metallization: Additional processes such as surface finishing (polishing, grinding) and metallization (sputtering, plating) can add to the overall cost.
5. Quantity: Economies of scale apply, meaning larger production runs typically result in lower per-unit costs due to efficiencies in material procurement, processing, and equipment utilization.
6. Quality and Performance Requirements: Substrates meeting higher performance standards (e.g., tighter dimensional tolerances, enhanced thermal conductivity) may involve additional costs in terms of materials and manufacturing processes.
7. Market Conditions: Supply and demand dynamics, as well as fluctuations in raw material costs and manufacturing overhead, can influence pricing.

To provide a rough estimate, Showa Denko substrates can range from several hundred dollars to several thousand dollars per square meter, depending on the above factors.
