An **integrated circuit** (**IC**) or a **microchip** is a set of electronic circuits (usually consisting of MOSFET transistors) on a small flat piece of semiconductor material (silicon). It is currently the dominant technological basis for computers.
+**[[Moore's law]]** has succesfully described the history of
+semiconductor integration for decades: in every two years, the
+number of transistors in an IC can be doubled. However, Moore's
+law has depended on increasing economic investments: **Moore's
+second law**, also known as **Rock's law**, states that the
+cost of a fabrication plant doubles every four years. The
+smaller the feature size, the more specialized and complexity
+is needed in equipment and processes. This has lead to extreme
+[[centralization]] of fabs.
