Aluminum hydroxide finds various applications in integrated circuits (ICs), primarily due to its excellent insulation and thermal conductivity properties. Here are some key applications of aluminum hydroxide in integrated circuits:
In integrated circuits, an insulating layer is used to isolate different levels of circuit components, preventing electrical interference between them. Aluminum hydroxide is often employed as a material for the insulating layer due to its superb insulation properties. It effectively isolates circuits, ensuring that electrical signals are transmitted between different levels without interference.
Integrated circuits generate heat during operation, and excessive heat can impact the performance of the circuit. Aluminum hydroxide’s thermal conductivity makes it an ideal material for thermal management. It can be used as a heat-dissipating layer, effectively conducting and dispersing the heat generated by the circuit, maintaining a stable operating temperature.
The particle form of aluminum hydroxide can be used as a filling material, mixed into polymers to enhance the thermal conductivity and mechanical properties of the polymer. This is particularly useful in integrated circuits with high thermal management requirements.
Metal Oxide Layer
The oxide form of aluminum hydroxide, namely aluminum oxide, can be used as part of a metal oxide layer. These layers are commonly used in the manufacture of capacitors and other electronic components.
Due to its insulating properties, aluminum hydroxide can also be used as part of dielectric materials, used in the manufacture of capacitors and other components that require excellent insulation performance.
