Key steps in the manufacturing process

In the process of manufacturing 30 micron substrates, execution of key steps is critical to achieving high quality and reliability. Below is a detailed description of these key steps:

Lithography: the precise process that defines the structure of a substrate

Photolithography is a sophisticated pattern transfer process that uses light-sensitive substances and photoresists to precisely define the structure of a substrate. In this step, a photoresist layer is first covered with a mask and then exposed using ultraviolet light, which causes chemical changes in specific areas of the photoresist. Next, a development and etching step is performed to define the structure of the 30-micron substrate by removing unnecessary parts.

Thin film deposition: precise coverage of substrate surface material

Thin film deposition is a key process for depositing materials on a substrate surface. Ensure film uniformity and consistency by controlling deposition parameters such as temperature and gas concentration.

Preparation process: Prepare the substrate to a thickness of 30 microns

The preparation process involves preparing layers of material to a thickness of 30 microns. This may involve multiple rounds of deposition and etching steps to gradually achieve the desired substrate thickness. Precise control of parameters at each step, such as deposition rate and etch rate, is critical to ensuring the final thickness and flatness of the substrate.

Copper Foil Bonding: The Key Role of Copper Foil in the Manufacturing Process

The copper foil bonding process is integral to the manufacturing of 30-micron substrates, playing a crucial role in enhancing their electrical conductivity and heat dissipation properties. This step involves securely attaching the copper foil to the substrate’s surface under high temperature and pressure conditions. This not only elevates the electrical performance of the substrate but also reinforces its overall strength and durability.

The effective execution of these key steps is key to ensuring the success of 30 micron substrate manufacturing, providing a solid foundation for high-performance packaging technology.
