Title: Choong-Hee Lee: Innovator in Silicon Crystallization Technology

Introduction

Choong-Hee Lee is a prominent inventor based in Suwon-si, South Korea. He has made significant contributions to the field of silicon crystallization, holding 2 patents that showcase his innovative approaches. His work primarily focuses on enhancing the efficiency and effectiveness of crystallization processes, which are crucial in the production of electronic components.

Latest Patents

One of Choong-Hee Lee's latest patents is a crystallization apparatus capable of locally crystallizing amorphous silicon. This apparatus includes a heat emission part, a support part, and a roller. The heat emission part emits heat upon receiving a heat emission source, while the support part supports the heat emission part and provides the heat emission source. The roller receives the heat emission part and has at least one opening to provide heat to a target, such as amorphous silicon. This method allows for local crystallization without causing damage to the substrate.

Another notable patent involves a method of forming crystallized silicon and fabricating thin film transistors and liquid crystal displays. This method includes forming an amorphous silicon layer on a substrate, followed by an insulating layer and a heat distributing metal layer. A thermite layer is then formed on the heat distributing metal layer. Ignition heat is applied to ignite the thermite layer, generating sufficient localized exothermic heat to crystallize the amorphous silicon layer. This innovative approach ensures that the substrate beneath the amorphous silicon layer remains undamaged by the localized crystallizing heat.
