\section*{Lab 1}
In my drawing (figure \ref{fig:lab1}), I drew a few of the details mentioned in Chapter 3 of the textbook.
A few clarifying notes:

\begin{itemize}
    \item I included the shallow and deep n+ wells, and the SiN spacers that were
        used to create them. According to the book, the shallow n+ wells help prevent
        hot electron damage and reduce short channel effects. However, the deeper
        wells are used to reduce resistance.
    \item I also added the silicide layer, which is used, from my understanding,
        to improve the conduactance of the transistor terminals. This layer
        is drawn in purple.
    \item I drew the the vias as metal 1 (solid blue). Electric colors them black,
        and apparently, tungsten is occasionally used to ensure better connections
        of the vias themselves.
\end{itemize}
