In recent years, with the development of high performance of various devices, the demand for miniaturization of components has been increasing. In this context, ROHM has long used the original micro-refinement technology to continuously promote technological innovation in component miniaturization.

In 2011, ROHM developed the world's smallest* chip resistor (0.3mm × 0.15mm), which is smaller than the 0402 (0.4mm × 0.2mm) size called the micronization limit; in 2012, it developed the world's smallest ※ semiconductor --- Zener diode (0.4mm × 0.2mm).

This time, the product lineup not only added 0402 Schottky barrier diode (SBD), but also is about to usher in mass production of 03015 chip resistors .

ROHM has achieved the miniaturization of these new processes that are different from the traditional ones, and the world's smallest ※ components with a remarkable dimensional accuracy (±10μm) are positioned as the RASMIDTM (ROHM Advanced Smart Micro Device) series.

In the future, ROHM will continue to promote the development of miniaturization of products, and develop more practical technologies including installation technology, and continue to expand the product lineup of this series of products, contributing to further miniaturization of equipment.

Miniaturized with a new process that is completely different from the traditional, the world's smallest ※ component series proud of its amazing dimensional accuracy (±10μm)

■ 0402 (0.4mm × 0.2mm) size Schottky barrier diode

Compared with the previous 0603 size products, the size has been reduced by 82% (volume ratio)
? Plan to sell samples from October 2013, mass production began in January 2014

■03015 (0.3mm × 0.15mm) size resistor

Compared with the previous 0402 size products, the size has been reduced by 56% (volume ratio).
? Samples have been sold since January 2012, and mass production is scheduled to begin in October 2013.

■0201 (0.2mm × 0.1mm) size resistor

Based on the size of the 03015 size product, the size is successfully reduced by 68% (volume ratio)
Plan to sell samples from October 2014

This product will be exhibited at the ROHM exhibition area of ​​the 15th China International Hi-Tech Fair (ELEXCON2013) held at the Shenzhen Convention and Exhibition Center from November 16th to 21st, 2013 (Booth No. 2B62). Welcome to experience!

<0402 (0.4 mm × 0.2 mm) size Schottky barrier diode>

ROHM uses the new technology unique to the RASMIDTM series to develop a world-class* grade Schottky barrier diode 0402 size (0.4mm × 0.2mm) for high-density placement for mobile devices such as smartphones.

The production base of this product is located at ROHM Apollo Device Co., Ltd. (Fukuoka Prefecture, Japan). It is expected to start selling samples from October 2013 (sample price: 20 yen), and will start monthly production of 5 million from January 2014. The scale of the project is put into mass production.

1. Through the original process technology, the world's smallest ※ 0402 size (0.4 mm × 0.2 mm)

Compared with the previous 0603 size (0.6mm × 0.3mm), this product has successfully reduced the size by 82%. It is very useful for high-performance and miniaturization of all devices that require small size and light weight, such as mobile phones and DSCs.

2. The main electrical characteristics such as forward voltage (VF) remain the same as "0603 size"

In general, the chip miniaturization of the diode is inversely related to the electrical characteristics. In order to break this opposite relationship, ROHM uses an exclusive chip component structure and ultra-precision machining technology. Not only the main electrical characteristics such as forward voltage (VF) are the same as those of the conventional products (0603 size), but also ultra-compact and super Light and thin.
