The first practically useful semiconductor device seems to have been the cat's whisker detector which was based on Bose's invention of 1904. For more information please see the wikipedia article entitled semiconductor.
Semiconductors aren't built, they are chemicals. Maybe you are thinking of semiconductor electronic components. The first semiconductor discovered was galena (lead sulfide) which was first used in a practical electronic component in 1874. The next semiconductor discovered was copper oxide which was first used in a practical electronic component in 1924. After that many others were discovered including selenium, germanium, and silicon. It was not practical to build electronic components using silicon until 1958 when Fairchild perfected their silicon mesa process, then in 1959 their silicon planar process.
Semiconductor resistor is a resistor body formed in a semiconductor substrate. The first and second conductive terminals are electrically connected to the resistor body at opposite ends.
The first modern semiconductor diode was made with germanium. These diodes were invented in ww2 for RADAR. But before that semiconductor diodes were made with galena (lead sulfide), copper oxide, and selenium. I have no idea which was "first".
The built-in potential is the potential difference established at the junction of two different materials, such as a p-n junction in a semiconductor device. It arises due to the electrostatic forces that separate the charge carriers across the junction, creating a barrier for the flow of current. This potential is an important parameter in determining the behavior of semiconductor devices.
According to Encyclopedia Britannica the first genuine solar cell was built around 1883 by Charles Fritts, who used junctions formed by coating selenium (a semiconductor) with an extremely thin layer of gold.
A semiconductor slice is used to make integrated circuits or ICs. It is also known as a semiconductor wafer or a semiconductor substrate.
jack kilby is a inventor. He studied at the University of Wisconsin. In 1958 he joined Texas Instruments; there he built the first integrated-circuit, a device in which all of a circuit's components are integrated on a single semiconductor surface.Read more: jack-kilby
