In an effort to allow high-density packaging for mobile devices, ROHM CO. Ltd. claims it has developed the world's smallest chip resistor, measuring just 0.3mm×0.15mm.
ROHM said it reduced the size of the 03015 chip resistor by 44% compared to the conventional 0402 (0.4mm×0.2mm), which had long been thought to be the limit of miniaturization. ROHM said it is developing chip 0201 resistors measuring 0.2mm×0.1mm.
To achieve this, ROHM scrapped conventional resistor manufacturing technologies and developed a manufacturing system using miniaturization techniques. It also reworked the dicing method, improving the tolerance of package dimensions in the cutting process to ±5µm. Consequently, dimensional accuracy improvements reduced stiction errors in the packaging process. ROHM also said that using corrosion-resistant gold on the surface of electrode enhanced solderability.
- The ROHM's unique process technology realized the world's smallest chip size.
