Matsushita Electric Develops 1 TB Super Capacity Memory with Stampsize Using Biotechnology

Matsushita Electric Industrial Co., Ltd. has developed a technology that can manufacture semiconductors with ultra-fine structure by using biotechnology.

This seems to make it possible to develop unexpected memory with stamp size of 1 TB (about 1000 GB) storage capacity. In other words, will mobile phones and laptop computers equipped with large capacity memory equivalent to desktop HDDs appear in the future?

Details are as below.

According to this release, Matsushita Electric Industrial Co., Ltd. has collaborated with Tohoku University, Tokyo Institute of Technology, Nara Institute of Science and Technology, and Osaka University to develop a single-digit nanometer-level ultrafine structure semiconductor It is said that he developed a technology to form the image.

It is realized by enclosing various inorganic compounds such as iron in "ferritin protein (ferritin)" of mammal's inner diameter of about 7 nanometers, but inhibits semiconductor characteristics to ferritin It has been hurdle until now that alkali metal ions such as sodium ions are included.

This is "ferritin protein". Place a metal compound contained in it on a silicon substrate.


However, due to the unique replacement washing newly developed, we succeeded in controlling alkali metal ion concentration in ferritin to 1/10 billion level without affecting semiconductor characteristics, We have developed a technology to adsorb ferritin, and developed heat treatment technology to reduce metallic compounds encapsulated in ferritin arranged to metal, leading to the development of technology for forming semiconductors with ultrafine structure.

I can not wait to be actually commercialized ... This is ....
