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.
ON Semiconductor was created in 1999.
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.
combination of two semiconductor
entire circuit is built into a single piece of semiconductor (chip); physical properties of semiconductor to large degree determine performance of the circuit; the most common integrated circuits such as microprocessors, memories, etc., are all monolithic.
Vitesse Semiconductor was created in 1984.
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.
It is a semiconductor.
Arsenic is not a semiconductor by itself, but it is commonly used as a dopant in semiconductor materials like silicon to alter their electrical properties. Arsenic increases the number of available charge carriers in the material, which can make it conduct electricity more effectively.
A semiconductor slice is used to make integrated circuits or ICs. It is also known as a semiconductor wafer or a semiconductor substrate.
ON Semiconductor was created in 1999.
Tungsten is really a semiconductor.
The population of ON Semiconductor is 21,000.
NaCl is not a semiconductor.
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.
Copper is a conductor but not a semiconductor.

p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
