Abstract
A better impedance match between a signal transmitting component and a signal transmitting component circuit in a semiconductor circuit is achieved by controlling the parameters of the conducting path coupling the signal transmitting and receiving components. The parameters are controlled such that the portion of the conducting path coupled to the transmitting component has a characteristic impedance generally matching the output impedance of the transmitting component and the portion of the conducting path coupled to the signal receiving component has a characteristic impedance generally matching the input impedance of the signal receiving component. The impedance in portions of the conducting path can controlled by varying the geometric cross-section of the conducting path, the composition of the portion of the conducting path, and/or the amount or nature of the doping of the portion of the conducting path.
