An LED having vertical topology and a method of making the same is capable of improving a luminous efficiency and reliability, and is also capable of achieving mass productivity. The method includes forming a semiconductor layer on a substrate; forming a first electrode on the semiconductor layer; forming a supporting layer on the first electrode; generating an acoustic stress wave at the interface between the substrate and semiconductor layer, thereby separating the substrate from the semiconductor layer; and forming a second electrode on the semiconductor layer exposed by the separation of the substrate.

Methods of forming integrated circuit devices include patterning an electrically insulating layer to support dual-damascene interconnect structures therein. The steps of patterning the electrically insulating layer include using multiple planarization layers having different porosity characteristics. Forming an interconnect structure within an integrated circuit device may include forming an electrically insulating layer on a substrate and forming at least one via hole extending at least partially through the electrically insulating layer. The at least one via hole is filled with a first electrically insulating material having a first porosity. The filled at least one via hole is then covered with a second electrically insulating material layer having a second porosity lower than the first porosity. The second electrically insulating material layer is selectively etched back to expose a first portion of the first electrically insulating material in the at least one via hole. The electrically insulating layer is selectively etched to define a trench therein that exposes a second portion of the first electrically insulating material in the at least one via hole. The first electrically insulating material, which has a relatively high degree of porosity, is then removed from the at least one via hole. This removal step may be performed using a relatively mild ashing process because of the high porosity of the first electrically insulating material.

A laser induced thermal imaging apparatus and a laser induced thermal imaging method capable of uniformly adhering a donor film to an acceptor substrate by use of a magnetic force to achieve an effective laser induced thermal imaging method; and a method for fabricating an organic light-emitting diode using the same. The laser induced thermal imaging apparatus includes: a chamber in which a contact frame having a magnetic substance is located, to press toward an acceptor substrate containing a magnet located on a substrate stage with an imaging layer of a donor film located between the acceptor substrate and the contact frame; and a laser oscillator to irradiate the donor film through openings in the contact frame. Accordingly, the laser induced thermal imaging apparatus applies an improved adhesion between the donor film and the substrate, producing an organic light-emitting diode having an improved life span, yield and reliability.

A laser induced thermal imaging (LITI) apparatus and a method of making an electronic device using the same are disclosed. The LITI apparatus includes a chamber, a substrate support, a contact frame, and a laser source or oscillator. The LITI apparatus transfers a transferable layer from a film donor device onto a surface of an intermediate electronic device. The LITI apparatus uses a magnetic force to provide a close contact between the transferable layer and the surface of the intermediate device. The magnetic force is generated by magnetic materials formed in two components of the LITI apparatus that are spaced apart interposing transferable layer and the surface of the intermediate device. Magnets or magnetic materials are formed in the two following components of the LITI apparatus: 1) the intermediate device and the film donor device; 2) the intermediate device and the contact frame; 3) the substrate support and the film donor device; or 4) the substrate support and the contact frame.
