- Rock's law or Moore's second law, named for Arthur Rock or Gordon Moore, says that the cost of a semiconductor chip fabrication plant doubles every four years. As of 2015, the price had already reached about 14 billion US dollars. Rock's law can be seen as the economic flip side to Moore's (first) law – that the number of transistors in a dense integrated circuit doubles every two years. The latter is a direct consequence of the ongoing growth of the capital-intensive semiconductor industry— innovative and popular products mean more profits, meaning more capital available to invest in ever higher levels of large-scale integration, which in turn leads to the creation of even more innovative products. The semiconductor industry has always been extremely capital-intensive, with ever-dropping manufacturing unit costs. Thus, the ultimate limits to growth of the industry will constrain the maximum amount of capital that can be invested in new products; at some point, Rock's Law will collide with Moore's Law. It has been suggested that fabrication plant costs have not increased as quickly as predicted by Rock's law – indeed plateauing in the late 1990s – and also that the fabrication plant cost per transistor (which has shown a pronounced downward trend) may be more relevant as a constraint on Moore's Law.

- Selon la loi de Rock, du nom de son découvreur Arthur Rock, le coût d'une fonderie de semi-conducteurs double tous les 4 ans- car le procédé de fabrication, la photolithographie, utilisé depuis une quarantaine d’années se rapproche toujours plus de ses limites physiques. En 2003, le prix d’une unité de fabrication était de l’ordre de 2 à 3 milliards de dollars. En 2004, pour la seule mise à niveau des installations, Intel a annoncé un investissement de plus 2 milliards de dollars dans son usine Fab12 en Arizona pour la fabrication de puces à partir de wafers de 300 mm de diamètre, qui ont remplacé les wafers 200 mm vers la fin 2005.
