A research team at the KAIST (Korea Advanced Institute of Science and Technology) has created a high performance ultrathin polymeric insulator that is meant for FETs (field effect transistors). The researchers made use of vaporized monomers for forming polymeric films that are mainly grown on several surfaces which also include plastics for producing a multipurpose insulator that caters to a wide array of needs of the next-gen electronic devices. FETs refer to the vital components used by each and every electronic device being used these days such as mobile phones, flat displays, and computers. 

FETs along with the three main electrodes namely drain, source, and gate consist of semiconductor channel layer and also insulating layer. The insulator placed within the FETs plays a vital role when it comes to having a control over the conducting capabilities of semiconductor channels. As a result, there is smooth flow of current in the translators. For minimal power and reliable operability of FETs, ultrathin and electrically robust insulators are of utmost importance. Traditionally, these insulators are generally made up of inorganic substances and inorganic materials such as nitrides and oxides that are build on hard surfaces like glass and silicon because of their impeccable insulating properties and durability.

But the problem with such insulators was that they could not be implemented in soft electronics because of their rigid properties and also their high processing temperatures. In the recent past, many researchers and scientists had studied and analyzed polymers as potential insulating materials which could be compatible with emerging semiconductor and soft substrates materials. The conventional technique that was used for developing polymer insulators had the disadvantage of limited surface coverage at very low thickness.
