Japan company,Rohm announced that it has successfully developed the world's smallest semiconductor and resistor, which is as small as sand. Manufacturers said the new product is expected to good application in the smart phone and other aspects of miniaturization , and thereafter will also consider the application of the results to the medical field, such as hearing aids and endoscopes and other instruments. New resistors and semiconductors will be from October this year and January next year production. Reportedly, the resistor length 0.3mm, width 0.15mm, smaller in size than previous products by 56%; semiconductor length 0.4mm, width 0.2mm, the volume reduced by 82%. Roma said they are further developing a smaller length 0.2mm, 0.1mm wide resistor. Resistors are essential parts of the control current, take the smart phone, for example, about 200 of which requires the use of resistors, semiconductors 5-6. Reducing the size of the semiconductor resistor and the benefits of self-evident.
