10 billion! Murata Manufacturing plans to spend 10 billion to triple the production of such components!

Murata Manufacturing Co., Ltd. plans to invest about 10 billion yen (about 500 million yuan) in Japan's Kanazawa Murata Manufacturing Co., Ltd., Sendai Murata Manufacturing Co., Ltd., and its Finnish subsidiary by 2028 to triple the production capacity of silicon capacitors to the current level. level. At present, silicon capacitor applications are limited to medical equipment, but in the future it is expected to expand to applications such as smartphones and servers, and companies are responding to demand by investing in increasing production.

Regarding the expansion of silicon capacitors, Murata has previously invested in related investments. On March 8, Murata Manufacturing announced that it will invest 50 million euros (approximately 7.2 billion yen) in its French subsidiary Murata Integrated Passive Solutions (formerly known as IPDiA, located in Caen, France) to build a new production line to Increase silicon capacitor production capacity until 2024.

For this expansion, according to the Nikkan Kogyo Shimbun, they plan to establish a system capable of producing the same silicon capacitors in Kanazawa, Sendai and Finland. They will retrofit existing thin-film plants for the production of high-frequency components (SAW filters).

At present, the application of silicon capacitors is mainly concentrated in fields such as implantable medical equipment, but its application range is expected to expand. For example, with the increasing functionality of smartphones, multiple components need to be installed in a limited space. Murata's silicon capacitors are very thin at 0.05mm thick, making them suitable for needs such as smartphones.

In addition, with the generation of artificial intelligence (AI) and the increase in the amount of data, the market demand for semiconductor packaging substrates for servers will also expand. The silicon capacitor can be mounted on the back surface of the package substrate or the like. "Demand for packaging substrates will increase in the future, although it has not yet appeared," said Noriyuki Nakajima, president of Murata Manufacturing Co., Ltd.

Murata Manufacturing Co., Ltd. is a global leader in the field of multilayer ceramic capacitors (MLCC). To expand its product line, the company acquired France's IPDiA (now Integrated) in 2016. They plan to advance standardization of equipment and technology while expanding production capacity.

A silicon capacitor is a component used to temporarily store and release electrical energy to stabilize voltage. It also reduces factors such as ESL (equivalent series inductance) that can cause digital equipment to malfunction.

Silicon capacitors are made of silicon material, which is similar to ordinary capacitors, with plates on the top and bottom, and a dielectric layer in the middle. The difference is that the dielectric layer is made of silicon material.

Silicon capacitors have many advantages in performance. Because the silicon material is used, the stability of silicon is relatively good, so silicon capacitors also have excellent high-frequency characteristics and temperature characteristics, extremely low bias characteristics, high reliability, and low-background characteristics. Silicon capacitors are also made smaller and thinner. Standardized silicon capacitors can be 100 microns, and customized ones can be 40-50 microns.

According to market research firm Transparency Market Research, the global silicon capacitor market will be worth $1.58 billion in 2021. It is expected to grow at a CAGR (Compound Annual Growth Rate) of 5.4% from 2022 to 2031. Meanwhile, according to a study by Mordor Intelligence, the global MLCC market size will reach $11.63 billion in 2021. It is expected to grow at a CAGR of 6.03% from 2022 to 2027.
