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.

Provided is a method of manufacturing a flash memory device. In a flash memory device using a self-aligned shallow trench isolation scheme, a buffer oxide layer is formed between a first polysilicon layer and a nitride layer. After a polishing process for forming a field oxide film is performed, a buffer oxide layer is used as an etch-prevention layer in the process of stripping the nitride layer and the buffer oxide layer is stripped in a cleaning process before a second polysilicon layer is deposited. It is thus possible not only to prevent phosphorous ions contained in an H3PO4 solution used in the process of stripping the nitride layer from diffusing into the grain boundary of the first polysilicon layer, but also to reduce the time when the first polysilicon layer is exposed to a HF cleaner used in the cleaning process before the second polysilicon layer is deposited. Therefore, the present invention has effects that it can enhance the properties of a gate oxide layer and a gate electrode by minimizing an attack of a fluorine radical contained in the HF cleaner against the first polysilicon layer.
