A thin film transistor with a self-aligned lightly-doped region and a fabrication method thereof. Commercial share of wallet is the portion of the spending wallet that is captured by a particular financial company. A longitudinal adjusting element is positioned between and connects the cannula insertion guide and housing of the device. Thereby, gate oxide film is formed so as to have a almost uniform thickness such that a thickness of a region directly above oxidation preventive film and a thickness of a region directly below gate electrode are almost the same is each other. The coupling between the two fixed cable coupling members is proportionally weaker than the independent coupling between the two fixed cable coupling members and the energy absorption system.
