\begin{frame}{Introduction}\includelogo
One of the biggest challenges on the design of modern electronic devices is the thermal control.
\vspace{1em}
In this work, it is proposed a solution by Classical Integral Transform Technique(CITT) to solve a heat conduction problem on Solid-State Electronics (SSE) considering heat generation and external convection.

\begin{frame}{Solid State Electronics (SSE)}\includelogo
Solid-state electronics (SSE) are those circuits or devices built entirely from solid materials and in which the electrons, or other charge carriers, are encapsulated within the solid material.
\vspace{0.5em}
Exemples: Transistors, Microprocessors, Random Access Memory (RAM), Itegrated Circuits (IC).

\begin{frame}{Substrate}\includelogo
Substrate is a solid substance and serve as the foundation upon which electronic devices such as transistors, diodes, and especially Integrated Circuits (ICs) are encapsulated.
\vspace{0.5em}
Example of substrate's materials:
\begin{itemize}
\item silicon
\item silicon dioxide
\item aluminum oxide
\item sapphire
\end{itemize}
The advantage of this is the superior insulation between adjacent transistors.

The nondimensionalization of the problem leads to the following mathematical formulation:

\small
\begin{gather*}\label{equation}
\frac{\partial^2\Theta}{\partial \xi^2}+
\beta^2 \frac{\partial^2\Theta}{\partial \eta^2}-(\Bi \gamma) \Theta =-G(\xi,\eta) \quad \text{for} \quad 0\leq \xi \leq 1 \quad \text{and} \quad 0\leq \eta \leq 1
\\
\left.\frac{\partial\Theta}{\partial \xi}\right|_{\xi=0}=0; \qquad \left.\frac{\partial\Theta}{\partial \eta}\right|_{\eta=0}=0; \\ \left.\frac{\partial\Theta}{\partial \xi}\right|_{\xi=1}=0; \qquad \left.\frac{\partial\Theta}{\partial \eta}\right|_{\eta=1}=0;

\section{Methodology}

%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Classical Integral Transform Technique}\includelogo
In order to solve the proposed problem, the Classical Integral Transform Technique (CITT) is applied, considering the appropriate Helmholtz Eigenvalue Problem in cartesian coordinates.
\begin{gather*}
\Psi_n''(\eta)+\lambda_n^2\Psi_n(\eta)=0 \\
\Psi_n'(0)=0; \quad \Psi_n'(1)=0.
\end{gather*}
where $\Psi(\eta)$ are the eigenfunctions and $\lambda_n$ are the eigenvalues. For this particular problem, the case where $\lambda=0$ also exists.
For $\lambda=0$, the solution of the eigenvalue problem is given by:
\begin{gather*}
\Psi_0(\eta)=1; \qquad \lambda_0=0;
\end{gather*}
%
And for $\lambda>0$:
\begin{gather*}
\Psi_n(\eta)=\cos(\lambda_n \eta); \qquad \lambda_n=n \pi, \quad \text{for} \quad n=1,2,3,\dots
\end{gather*}
\end{frame}
%^^^^^^^^^^^^^^^^^^^^^^^^^^

%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{frame}{Classical Integral Transform Technique}\includelogo
To apply the CITT, the transformation pair is defined.
\begin{varblock}[10cm]{Transformation Pair}
\begin{align*}
%\label{transformada}\quad
\text{Transformation} \quad &\Rightarrow \quad
\bar{\Theta}_n(\xi)=\int_{0}^{1}\Theta\Psi_n(\eta)\dd\eta\\
%\qquad\label{eq:inversion}
\text{Inversion} \quad & \Rightarrow \quad \Theta= \sum_{n=0}^{\infty} \frac{ \bar{\Theta}_n(\xi)\Psi_n(\eta)}{N_n}
\end{align*}
\vspace{0em}
\end{varblock}
$N_n$ is the norm and is defined as:
%
\begin{gather*}
N_n=\int_{0}^{1}\Psi_n^2 \dd \eta
\end{gather*}
\end{frame}
%^^^^^^^^^^^^^^^^^^^^^^^^^^

%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\begin{frame}{Classical Integral Transform Technique}\includelogo
The dimensionless diferential equation is written again, \\
multiplied by $\Psi_n$ and integrated in the domain for $\eta$.
\begin{gather*}
\int_{0}^{1}\frac{\partial ^2 \Theta}{\partial\xi ^2} \Psi_n d\eta+\beta^2\int_{0}^{1}\frac{\partial ^2 \Theta}{\partial\eta ^2}\Psi_n d\eta - \Bi\gamma\int_{0}^{1}\Theta\Psi_n d\eta=- \int_{0}^{1}G\Psi_n d\eta
\end{gather*}
The transformed equation is obtained and admits an analytical solution.
\begin{columns}[t]
\begin{column}{5cm}
For $\lambda > 0$:
\small
\begin{gather*}
%\text{For}\quad\lambda > 0\rightarrow
\bar{\Theta}_n''+(-\beta^2\lambda_n^2-\Bi\gamma)\bar{\Theta}_n=-\bar{G}_n(\xi)\\
\bar{\Theta}_n'(0)=0; \quad \bar{\Theta}_n'(1)=0\\
%\end{gather*}
%\begin{gather*}
\text{where} \\\bar{G}_n(\xi)= \int_{0}^{1}G(\xi,\eta)\Psi_n(\eta)\dd\eta
\end{gather*}
\end{column}
\begin{column}{5cm}
For $\lambda = 0$:
\small
\begin{gather*}
\bar{\Theta}_0''-(\Bi\gamma)\bar{\Theta}_0=-\bar{G}_0(\xi)\\
\bar{\Theta}_0'(0)=0; \quad \bar{\Theta}_0'(1)=0\\
%\end{gather*}
%\begin{gather*}
\text{where}\\\bar{G}_0(\xi)= \int_{0}^{1}G(\xi,\eta)\dd\eta

The transformed equations admit a analytical solutions. \\[1em]
In order to obtain the final temperature field, the inversion formula must be utilized and the summation must be truncated to a finite value ($\nmax$).
\begin{align*}
\text{Inversion} \quad & \Rightarrow \quad \Theta= \sum_{n=0}^{\nmax} \frac{ \bar{\Theta}_n(\xi)\Psi_n(\eta)}{N_n}

\begin{frame}{Conclusions}\includelogo
\begin{itemize}
\item The solution is fully analytical
\vspace{2em}
\item CITT had a great performance to obtain high accuracy with very few terms in the solution summation.
\vspace{2em}
\item This is a preliminary work and for near future works, one can propose: Use of the complete Heat Generation and variation of the heat conductivity.
\end{itemize}
