In one aspect of the present invention, a method of making an OLED device comprises providing a substrate; a first electrode, a conductive bus line over the substrate and an organic electroluminescent media over the first electrode and over the conductive bus line. A laser that operating at a predetermined wavelength and is scanned over the conductive bus line in a predetermined direction so that the conductive bus line absorbs sufficient energy to cause the ablation a portion of the organic electroluminescent media over the conductive bus line thereby forming an opening in the organic electroluminescent media. The width of the laser beam in the predetermined direction is less than four times the width of the conductive bus line; and forming a second electrode over the organic electroluminescent media, the first electrode, and through the opening in the organic electroluminescent media.

Electrical connection in OLED devices

A method of making micro-structure devices by coating a first layer of resist () on a substrate (). A pattern is created on the substrate by radiation induced thermal removal of the resist.

Laser ablation resist

A method for forming a resist pattern on a substrate () places a donor element () having a layer of thermoresist material proximate the substrate. A gap is maintained such that the surface of the layer of thermoresist material is spaced apart from the surface of the substrate by a number of spacing elements. Thermal energy is directed toward the donor element () according to the resist pattern, whereby a portion of thermoresist material is transferred from the donor element () across the gap by ablative transfer and is deposited onto the substrate () forming the resist pattern.
