Abstract
An embodiment is a method and apparatus to treat surface of polymer for printing. Surface of a polymer having a surface energy modified for a time period to control a feature characteristic and/or provide a hysteresis behavior. A material is printed on the surface to form a circuit pattern having at least one of the controlled feature characteristic and the hysteresis behavior.
Claims25
A method comprising:
- modifying surface energy of surface of a polymer for a time period to control a feature characteristic and/or provide a hysteresis behavior;
- and
- printing a material on the surface to form a circuit pattern having at least one of the controlled feature characteristic and the hysteresis behavior.
An apparatus comprising:
- a dielectric layer made of a polymer having a surface with modified surface energy, the modified surface energy controlling a feature characteristic and/or providing a hysteresis behavior;
- and
- a circuit pattern printed on the surface, the circuit pattern having at least one of the controlled feature characteristic and the hysteresis behavior.
A system comprising:
- at least one of an ultra-violet (UV) source and an ozone-generating source that generates ozone;
- a polymer having a surface exposed to/under the at least one of the UV source and the ozone-generating source for a pre-determined time period, the surface having a surface energy modified to control a feature characteristic and/or provide a hysteresis behavior;
- and
- an ink jet printer to print a circuit pattern on the surface with the modified surface energy.
