This presentation deals with a means of transforming membrane-type electronic devices into desirable three-dimensional shapes in mild and stable manners. The strategy begins with creating printable thin structure of electronic devices and supportive plastic (ABS copolymer used in this study) framework separately and lamination process. ABS framework serves as a mechanical supporter and undergoes plasticization and transformation by thermal annealing or plasticizer. The optical, mechanical, and electrical analysis show that plasticization releases stress concentration on the device layer, frazile area in perticular, and allows 3D transformation without electrical failure. Finally, some examples of 3D electronic devices such as image sensor arrays, LED displays, IGZO transistors developed using this method will be demonstrated. |
