Abstract Scope |
There is currently a high demand for materials and manufacturing technology which realize high-definition, low-cost, energy-saving displays. Since the 2000s, there has been a shift towards oxide semiconductors as materials for displays’ field-effect transistors (FETs) from conventional silicon-based materials.
Leading manufacturers have successfully entered volume production with display FETs fabricated with crystalline oxide semiconductor materials. The materials were discovered by Semiconductor Energy Laboratory Co., Ltd., and using the materials for FETs enables high-definition displays in a variety of form factors. More and more OLED display products carry this technology, and further proliferation is expected. In my presentation, I will introduce the fundamental properties and FET characteristics of crystalline oxide semiconductor materials and report examples of its real-world application. |
