Impurity diffusion definition
WitrynaIn impurity diffused areas (103, 106) of the respective off transistors (126, 127), dummy via contacts (116, 117) are arranged. patents-wipo Provided is an impurity - diffusing composition comprising (A) a polysiloxane represented by general formula (1) and (B) an impurity - diffusing component. WitrynaIn Section 3.1, the various mechanisms for diffusion of impurities in silicon are introduced and discussed. Most important for impurities residing predominantly on substitutional sites are mechanisms in which they form mobile pairs with intrinsic point defects. The energetics of such pairs is discussed in detail in Section 3.2.
