Patent ID: 8883053

Claim:
A method for fabricating a flexible electronic device, comprising: providing a support substrate with a top surface; subjecting a part of the top surface of the support substrate with a surface treatment, thereby forming a mold release region, wherein an adhesive region is the part of the top surface beyond the mold release region; forming a flexible film on the top surface, wherein the flexible film covers the mold release region and the adhesive region; forming an electronic element on the flexible film; and cutting the flexible film within the mold release region to isolate a flexible electronic device from the support substrate, wherein the surface treatment comprises providing a chemical agent to react with the top surface of the support substrate; and wherein the chemical agent has the structure represented by wherein w is C, Si, or Ge; X is S, or Se; Y is C, or S; R 1 , R 2 , and R 3 are independent and comprise H, alkenyl group, alkyl group, or —OR; R is C 1-18 alkyl group; R 4 is F, Br, I, carboxyl group, amino group, amine group, cyano group, amide group, alkyl halide group, or combinations thereof; R 5 is Li; and R 6 , R 7 , and R 8 are independent and comprise F, Cl, Br, I, alkenyl group, alkyl group, carboxyl group, amino group, amine group, cyano group, amide group, alkyl halide group, or combinations thereof.
