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.

A method for forming a semiconductor device includes forming a partition line pattern and a partition pad pattern connected to an end part of the partition line pattern over the semiconductor substrate. Spacer insulation layers are formed at sidewalls of the partition line pattern and the partition pad pattern. A gap-filling layer is formed between the spacer insulation layers. A first cutting mask pattern is formed to expose a connecting part between the partition line pattern and the partition pad pattern. The partition line pattern and the gap-filling layer adjacent to the spacer insulation layer are removed using the first cutting mask pattern as a mask. A second cutting mask pattern including a first pattern and a second pattern are formed. The spacer insulation layer is removed using the second cutting mask pattern as a mask to form a gate trench in the substrate.
