National Institute of Advanced Industrial Science and Technology (AIST) Prints Memory on Plastic Substrate.


Tokyo, Japan, Dec 20, 2005 - (JCN) - The Organic Semiconductor A semiconductor made from a carbon-based material. For example, light-emitting polymers (LEPs) are organic semiconductors. Contrast with inorganic semiconductor.

) has prototyped a memory device that has a 3x3 memory array printed on a flexible plastic film substrate.

The research group used a soluble biopolymer bi·o·pol·y·mer (b-pl material with a bar-like helix structure to create a ferroelectric Refers to a material that functions similarly to a ferromagnetic material in that it can be polarized into two states. Ferroelectric devices generally do not have any "ferrous" (iron) in them. See FeRAM and ferroelectric capacitor. thin film A microscopically thin layer of material that is deposited onto a metal, ceramic or semiconductor base. Typically less than one micron thick, thin films can be conductive or dielectric (non-conductive). For example, the top metallic layer on a chip and the coating on magnetic disks are thin films. See sputtering. by changing inter-molecular interactions by controlling the molecular weight and molecular structure of the biopolymer.

Then, the group has made a two-terminal device that has the ferroelectric thin film, treated as a dielectric layer, placed between electrodes, and confirmed that the device demonstrates memory capability.

Using the ferroelectric biopolymer thin film and an organic semiconductor, the group has prototyped a 3x3-pixel-equivalent memory array screen-printed on a flexible plastic film and confirmed that the device retains a two-digit drain current on/off ratio for more than 10 days after power is turned off.
