Examples of Technology Application ~Product Introduction~ Murata’s Unique Technology Creates New Markets: Multi-layer LCP product

The greatest strength of Murata’s Multi-layer LCP product lies in its excellent high-frequency performance.
Its low-loss signal transmission in the high-frequency range provides significant value in mobile communication devices, where wireless data transmission speeds continue to increase in products such as smartphones, tablets, and wearable devices.
By suppressing signal degradation and maintaining stable communication quality, Multi-layer LCP product contributes to performance improvement of communication equipment.
The core technologies behind Multi-layer LCP product are Murata’s multilayer technology, cultivated through products such as Multilayer Ceramic Capacitors (MLCC), and its proprietary high-performance resin materials.
Unlike conventional multilayer resin substrates, Multi-layer LCP product employs a unique process that enables single-step pressing without the use of adhesives.
This technology solves challenges that were difficult to address with conventional resin substrates, including shape retention and humidity resistance.

In addition, laser cutting is used in the product singulation process, allowing flexible adaptation to complex outer-shape requirements.
Because no molds are required, design changes are easy, enabling shorter lead times and lower costs.

Furthermore, materials used in Multi-layer LCP products excel in forming and retaining three-dimensional shapes.
Conventional FPCs (flexible printed circuits) often suffer from springback, which makes shape retention difficult.
Multi-layer LCP product overcomes this issue through its material properties and bending process.
Because the bent shape can be maintained as is, integration into enclosures becomes easier, contributing to improved assembly efficiency and reduced man-hours.

Multi-layer LCP product continues to evolve in its structure, materials, and manufacturing processes to meet the growing demands for higher speed, larger capacity, and higher-frequency communications in smartphones, wearable devices, and other applications.

In the early stages of development, Multi-layer LCP product was mainly used for transmission lines and antenna applications.
Subsequently, modularization and collaboration with other Murata products expanded its range of applications.

In recent years, with a view toward the evolution of 5G (fifth-generation mobile communications) and future 6G (sixth-generation mobile communications), Murata has been advancing development aimed at lower dielectric constants, further miniaturization, and higher reliability.

In 2025, Murata began mass production of the world’s first ultra-low dielectric constant LCP flexible substrate incorporating a hollow structure.
By adopting a unique design with hollow regions inside the substrate, this product achieves an extremely low dielectric constant (Dk) of less than 2.0, significantly reducing transmission loss.

In this way, Multi-layer LCP product continues to advance low-loss signal transmission and highly flexible three-dimensional structural technologies by leveraging the high degree of structural freedom made possible by its proprietary batch lamination technology.
Murata will continue to deliver products that contribute significantly to the realization of next-generation devices.
