Murata: Global leader in precision ceramic technology
Brand genes and technological inheritance
Murata Manufacturing Co., Ltd. was founded in 1944 and is headquartered in Kyoto, Japan. With the mission of "contributing to social progress through innovation," it has gradually grown into a benchmark enterprise in the global electronic components industry. Its technological genes can be traced back to the in-depth research and development of ceramic materials: founder Akira Murata focused on the commercialization of barium titanate (BaTiO) ceramics after World War II, successfully developing high-frequency dielectric ceramics, laying the foundation for the subsequent capacitor revolution.
Construction of core technology barriers
Ceramic Materials Science
Murata has built three major technology platforms in the field of materials:
High frequency dielectric ceramics: Through nanoscale powder control technology, precise control of ε r (dielectric constant) is achieved. Its GRM series MLCC (multi-layer ceramic capacitor) has a loss tangent (tan δ) as low as 0.0002 in the 5G frequency band (24GHz-52GHz), which is 30% higher than the industry average.
Semiconductor ceramics: Developed strontium titanate (SrTiO ∝) based PTC thermistors that exhibit sudden resistance changes in the temperature range of -40 ℃ to+150 ℃, and are widely used in thermal management systems for new energy vehicle batteries.
Piezoelectric ceramics: By optimizing the polarization process of lead zirconate titanate (PZT) material, the sensitivity of ultrasonic sensors can reach 0.1Pa level, empowering smartphone fingerprint recognition and medical ultrasound imaging.
Precision manufacturing process
Murata's manufacturing system integrates semiconductor grade precision control:
Thin film deposition technology: Using atomic layer deposition (ALD) process, more than 1000 layers of dielectric stacking are achieved on a 0.2 × 0.1mm chip, and the capacitance of 008004 size (0.25 × 0.125mm) exceeds 0.1 μ F.
Laser resistance adjustment technology: By using femtosecond laser to nanoscale adjust the resistance layer, the accuracy of 0402 size resistance can reach ± 0.1%, meeting the strict requirements of spacecraft attitude control system.
3D packaging technology: Developed WLP (wafer level packaging) process, integrating inductors, capacitors, and resistors into a 0.9 × 0.5mm module, promoting the evolution of TWS earphones towards lead-free and miniaturization.
