Instructions on how to build electronic devices
Assuming from you username that you want to do this to learn about the properties of these devices rather than having some notion of it being in some way practical to construct these devices at home rather than buy them.

This is a bit like saying you want to forge your own girders in order to understand how skyscrapers work, sure you can make something at home with a lot of time &amp; effort, but it will be a long way off what can be achieved by a multi-million pound/dollar factory with multi-million pound/dollar high-tech machinery that is simply not possible to replicate on a smaller scale.

The construction and methods of manufacturing diodes, transistors, FETs are widely described, starting with their respective Wikipedia entries, and I'm not going to do your googling for you. Certainly people made the first / very early diodes and transistors from lumps of stuff in ways that are easily replicated.
