Experiences with ion implantation into E/VAC (ethylene-vinyl-acetate copolymer) or EVA, copolymer for biological-chemical applications suggested the use of this polymer as a promising material for “bipolar like” transistor architecture. Recently in the literature various devices were proposed, using conducting or semiconducting polymer materials for FET or Permeable Base Transistor Polymer Grid Transistor, PGT. Using a 90 KeV energy Ar+ beam, we bombarded an EVA film on both faces and used this film in a cell potential of an ion selective electrode. The results show a sharp increase in ion selectivity [K+] almost reaching the theoretical value. Additional ion implantation experiences and subsequent electrical characterization envisaged that this polymer could have a potential semiconducting behavior like some others polymers mentioned in the literature. This potential material behavior, motivated us to design some new transistor structures. Planar architecture of such device are suggested and open a new field of research and development in this area.
