....Key Words: substrate contacts, subtrate noise, mixed signal, epitaxial and non epitaxial technologies I. Introduction Substrate noise can affect the integrity of on chip analog and digital signals. Substrate noise in analog applications has received a great deal of attention in the past decade [1 6], particularly driven by the high resolution analog signal processing circuits operating in a noisy mixed signal environment such as in analog to digital (A D) or digital to analog (D A) converters. Substrate noise in digital applications has received far less attention because digital circuits ....
.... digital system (digital circuits exhibit a noise margin) A deleterious amount of substrate noise, however, can be exceeded in certain applications, such as in mixed signal smart power circuits [7,8] Different aspects related to the substrate noise problem have been analyzed in the literature [1 6]. The flow of substrate noise into the substrate has been qualitatively described by Wooley [1] The magnitude of the substrate noise together with related nonuniformities within the substrate have been shown to be the two primary factors that influence the noise behavior of digital circuits ....

A number of articles [1 5] have reported experimentally observed noise waveforms caused by the high speed switc hing of the on chip digital CMOS circuits in mixedsignal systems.

....[3, 5] Thus, in order to model coupling effects, it is sufficient to solve Laplace s equation inside the substrate with appropriate boundary and interface conditions. Many techniques have been used to solve this problem, including Finite Element (FEM) and Finite Difference (FD) methods [2, 6, 7, 8]. However, for complex layouts the number of unknowns resulting from the discretization of the three dimensional substrate volume may become too large for practical purposes. Boundary Element methods (BEM) are very appealing for the solution of this type of problems because the size of the matrix ....

....of the substrate electromagnetic interactions which rely on detailed numerical analysis are in general more reliable and accurate. Examples of 3D techniques include Finite Element (FEM) and Finite Diference (FD) numerical methods for computing all the currents and voltages in the substrate [2, 3, 4, 5, 6]. These techniques perform a full domain discretization on the large but bounded substrate and can easily handle irregular substrates (wells, doping profiles, etc) Unfortunately such methods are impractical for anything but simple problems, since the number of unknowns resulting from the ....

....[4] Several approaches have been presented in the past to attempt to quantify the effects of noise coupling through the substrate. Examples of such techniques include Finite Element (FEM) and Finite Diference (FD) numerical methods for computing all the currents and voltages in the substrate [1, 2, 5, 6, 7]. Unfortunately such methods are impractical for anything but simple problems, since the number of unknowns resulting from the discretization is too large because of volume meshing of the entire substrate.
