유연소자는 딱딱한 기판에 형성된 소자와는 달리 반복적인 스트레스가 가해져도 소자의 특성을 유지하며, 쉽게 구부러지는 특성을 가지고 있어서, 플렉시블 디스플레이, 터치 스크린 등의 구부러지는 전자부품, 또는 자유 곡면 위에 부착 가능한 센서 등에 사용될 수 있다. Unlike devices formed on a rigid substrate, flexible devices maintain the characteristics of the device even when repeated stress is applied and have easy bending characteristics. Therefore, flexible devices can be used for flexible electronic devices such as a display, a touch screen, Sensor or the like.

종래기술에 의하면, 이러한 유연소자는 일반적으로 기능성 세라믹/금속 소재 등을 유연한 고분자 소재와 혼합하여 유연한 필름 형태로 제조한 후, 전극 증착 등의 후속 공정을 통하여 만들어진다. 또는, 딱딱한 기판 혹은 특수하게 설계된 웨이퍼, 보다 상세하게는 SOI(silicon on insulator), GaN, GaAs 등으로 구성된 반도체용 웨이퍼 위에 반도체 공정을 사용하여 소자를 구현하고, 이를 식각 공정과 전사 공정을 통해 유연기판에 소자를 구현하기도 한다. According to the prior art, such a flexible device is generally manufactured by mixing a functional ceramic / metal material with a flexible polymer material to form a flexible film, and then performing a subsequent process such as electrode deposition. Alternatively, devices can be fabricated on semiconductor wafers composed of rigid substrates or specially designed wafers, more specifically, silicon on insulators (SOI), GaN, GaAs, etc., and processed by etching Devices may be implemented on the substrate.
