Samsung Electronics recently unveiled its focus with respect to the development status of the company’s next-generation capacitors. This revelation is made at the “Seminar on the Technology of Mounting Semiconductor Fusion Parts”. This event was held at the Gyeonggi Suwon Convention Center on October 14.
“MLCCs (laminated ceramic capacitors), which are the mainstay of the discrete capacitor market at present, are virtually impossible to reduce their size to less than 0.2 mm (200 μm). Accordingly, Samsung Electronics is developing the world’s smallest discrete capacitor, CCW (Ceramic Capacitor Wire), which is more compact than the MLCC, as its own patented technology. The markets we are currently targeting are small IT devices, HPC, and 5G.”
Capacitor and its types (MLCC & CCWs)
To make aware of, a capacitor is an electronic component that can store charge temporarily. Additionally, it is responsible for modulating the constant flow of current in the circuit while preventing electromagnetic interference between components.
Simultaneously, it is divided into various categories and it is dependent on the dielectric. Whereas, the MLCC is currently the most widely used in the electronics industry. Because of the fact that it is easy to implement a smaller form factor compared to those conventional capacitors respectively.
“MLCC is a promising technology whose market size is projected to be between 30 trillion and 40 trillion won in the next few years, but customers are currently demanding smaller and more electrically capable capacitors,” explained AL. “Samsung Electronics is developing CCW, a μm-class capacitor that has not been commercialized until now.”
Talking about CCWs have a wire shape as compared to MLCCs that come in traditional cube shape (0.4 mm wide x 0.2 mm long). Moreover, the capacitor which has been implemented by Samsung Electronics has a size of 100μm. It is achieved by coating the wire with ceramic and metal. The primary factor in doing so is that the capacitor is put as close to the chip as possible in a small form factor. The advantage of doing so is maintaining high performance even in high-frequency environments with fast currents.
Target segment
Samsung Electronics is targeting to subdivide CCW into components and PCBs with built-in CCW and integrated chips respectively. Also, it is used in small IT devices such as smartwatches, HPC, and 5G in the high-frequency band.
“MLCC has the problem that it is difficult for current to come in and out quickly in a high-frequency environment because it is a multi-layered structure, whereas CCW expects to show superior performance in a single-layered high-parking environment,” he said, adding, “You can think of it as a high-frequency, dedicated capacitor technology that didn’t exist in the world.”
Concurrently, the Korea-Japan Semiconductor Fusion Parts Mounting Technology Seminar was organized by the Korea Mounting Industry Association. The motive of the event is to introduce the trends in ultra-modern and futuristic semiconductor packaging and mounting technology. The participant of the events are certainly the big giants and includes Samsung Electronics, SK Hynix, Simtech, Shin Arti-Ann, Japan’s MEC, and Union Tools.
