Abstract: Protecting a FET from plasma damage during FEOL processing by forming a FET-like structure in conjunction with and adjacent to an FET, in a same well as the FET, but having a body doped opposite to the well polarity. The FET-like structure is formed with thinner oxide than the gate oxide of the FET, has a gate structure (poly) connected with the gate of the FET, and may be shorted out by the first metal layer (M1).

Abstract: A method of producing a metal oxide semiconductor field effect transistor (MOSFET) creates a transistor by patterning a gate structure over a substrate, forming spacers on sides of the gate structure, and forming conductor regions within the substrate on alternate sides of the gate stack. The gate structure and the conductor regions make up the transistor. In order to reduce high power plasma induced damage, the method initially applies a first plasma having a first power level to the transistor to form a first stress layer over the transistor. After the first lower-power plasma is applied, the method then applies a second plasma having a second power level to the transistor to from a second stress layer over the first stress layer. The second power level is higher (e.g., at least 5 times higher) than the first power level.
