Desenhando Diagrama de Esfera de Processo Linear

Question

Alguém sabe como desenhar um diagrama de fluxo de processo simples como este?

Answer 1

Bem, se você realmente quisesse, poderia desenhá-lo como uma árvore. O conteúdo dos nós é descaradamente retiradoResposta de R. Schumacher.

Aqui está um exemplo usando forest.

\documentclass[tikz,border=5pt]{standalone}
\usepackage{forest}
\usetikzlibrary{arrows.meta}

\begin{document}

  \begin{forest}
    for tree={
      delay={
        label/.wrap pgfmath arg={[font=\sffamily, anchor=west]right:#1}{content()},
        content={},
        circle,
        fill,
        inner sep=1.5pt,
        parent anchor=center,
        child anchor=center
      },
      edge={thick},
      if n children=0{
        l sep+=-15pt,
        append={
          [, edge={thick, -{Triangle[]}}]
        }
      }{}
    }
    [{Ge(100nm)--on--Si substrate}
      [{Hydrogen ion Shower Doping}
        [{Native Oxide Removal (HF:H$_2$O-1:100, 30 sec)}
          [{Ni /TiN (10 nm/10 nm) Deposition}
            [{RTP for germanidation (400$^o$C, 30 sec)}
              [{Post-germanidation Annealing}]]]]]]
  \end{forest}

\end{document}

Esta é uma versão aproximada do que você deseja. Eu modifiquei o código deComo você pode criar uma linha do tempo vertical? O único item que falta é a seta para baixo (ainda pensando nisso)
