What does the interface between lead(s) and the silicon chip look like inside a semiconductor package?
For a leaded semiconductor, like a diode or a transistor, one of the leads is usually the same piece of metal as the copper pad/heat spreader on the back, which is also shorted to one of the junctions ...

What is the difference between TO-3 and TO-204AA packaging?
I am trying to build a circuit for a power amplifier and TO-204AA is the packaging used in the circuit diagram.
KiCad does not have TO-204AA but it has TO-3.
Looking at the image below you will see ...
