Modern silicon transistors are by layering a semi conductor material on top of a conductor material on top of a semi conductor material. Various materials have been tried to improve the effeciency of the transistor. Most transistors these days come as part of an intergrated circuit or IC
germanium or silicon crystal

computer's chips and contact are made with silicon.
A transistor is a solid device consisting of two charged semiconductors sandwiching a very thin piece of an oppositely-charged semiconductor. The thin piece might even be a layer of oxidation on the semiconductor surface. These earlier and more sensitive (and delicate) transistors were made of the semiconductor, Germanium. The later, more sturdy transistors were and are made with silicon.
Silicon is a metal itself. It is not made of anything else but for silicon
Silicon chip
Computer chips are made out of lots of tiny transistors, a little bit of superconductive silicon and a huge amount of engineering.

The element silicon is to be found in 'sand' which is made from quartz which is silicon dioxide.
Silicon can be made from sand through a process called the "Silicon Extraction Process." In this process, sand (which is mostly made of silicon dioxide) is heated with carbon in an electric arc furnace to produce silicon. The carbon reacts with the oxygen in the silicon dioxide, leaving behind pure silicon. This method is commonly used in the production of silicon for various industrial applications.
A silicon transistor is a transistor made of silicon.
