Method of using an insulator spacer to form a narrow base width lateral bipolar junction transistor |
摘要 |
A process has been developed in which narrow base width, lateral bipolar junction transistors, and narrow channel length MOSFET devices, can be simultaneously fabricated, in a silicon on insulator layer. The narrow base width is defined by the width of an insulator sidewall spacer, formed on the sides of a polysilicon gate structure. The narrow base width, resulting in increased transistor gain and switching speed, along with reductions in parasitic capacitances, due to placing devices in a silicon on insulator layer, result in enhanced device performance.
