Process Optimization of Deposition Conditions for Low Temperature Thin Film Insulators used in Thin Film Transistors Displays

Deposition process for thin insulator used in polysilicon gate dielectric of thin film transistors are optimized. Silane and N2O plasma are used to form SiO2 layers at temperatures below 150 ºC. The deposition conditions as well as system operating parameters such as pressure, temperature, gas flow ratios, total flow rate and plasma power are also studied and their effects are discussed.  The p...

Low-temperature thin-film deposition and crystallization.

Crystalline oxide films are important components in a wide array of electronic and optical devices, and their study and manufacture involve major aspects of current science and technology. A plethora of methods, such as sputtering, chemical vapor deposition, pulsed laser deposition, and sol-gel, are commonly used to deposit these films, and many new techniques are being developed (1). In each o...

Effect of Surface Energy on Pentacene Thin-Film Growth and Organic Thin Film Transistor Characteristics

In this study, we discuss pentacene-based organic thin films grown on a self-assembled monolayer (SAM)-treated dielectric with various functional groups and molecular lengths. The functional groups and molecular lengths on the dielectric surface were modified using a SAM treatment followed by ultra violet (UV) light exposure. Surface energy was used to observe the surface polarity variation dur...
