The tools needed to build transistors from scratch are not common tools in home labs. Here are some of the less common tools: • Nitrogen tank • Kiln • Hydrofluoric acid (HF) • Phosphosilicate film • Prime silicon wafers • Vinyl sticker replaces the photoresist of the mask • Color table to identify the thickness of the oxide layer Reference details： https://www.newbecca.com/product/41286648220 https://img.alicdn.com/imgextra/i4/2207691322/TB2m.YxaN6I8KJjSszfXXaZVXXa_!!2207691322.jpg |

So what is your question? |

If you want to build your own transistor, it is actually quite easy using two point contacts closely spaced on a piece of germanium. Two germanium diodes provide all the necessary parts. Then you have to 'burn in' the junctions with the right voltages and currents. The result is a quite respectable point contact germanium transistor. |

Mullard OC50 and OC51 of 1952 were germanium point contact. http://www.wylie.org.uk/technology/semics/Mullard/Mullard.htm |
