Integrated Passive Devices (IPDs) are manufactured using integrated circuit processing methods similar to those utilized in semiconductor fabrication, although they are not limited to silicon substrates. The increasing importance of these devices is largely attributed to the continued push toward miniaturization in wireless technology.
The main benefit of employing thin film technology in the development of these devices is its capacity to achieve extremely close component matching, high area density, and consistent, repeatable performance. This is especially advantageous in applications where space is at a premium and reliability is crucial.
To produce these thin film devices and components, companies often rely on KDF Technologies' sputtering systems. These systems can deposit a broad range of materials—including gold (Au), chromium (Cr), titanium (Ti), copper (Cu), tantalum (Ta), tantalum nitride (TaN), and nickel-chromium (NiCr)—which are crucial for producing high-quality IPDs and thin film circuits.
This technology supports the industry's demand for efficient, dependable, and miniaturized components across diverse wireless applications.
