Moore's second law

Last updated

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. [1] As of 2015, the price had already reached about 14 billion US dollars. [2]

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.[ citation needed ]

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. [3] [4] [5]

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 [6] – and also that the fabrication plant cost per transistor (which has shown a pronounced downward trend [6] ) may be more relevant as a constraint on Moore's Law.

An integrated circuit, also known as a microchip or IC, is a small electronic device made up of multiple interconnected electronic components such as transistors, resistors, and capacitors. These components are etched onto a small piece of semiconductor material, usually silicon. Integrated circuits are used in a wide range of electronic devices, including computers, smartphones, and televisions, to perform various functions such as processing and storing information. They have greatly impacted the field of electronics by enabling device miniaturization and enhanced functionality.

Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as computer processors, microcontrollers, and memory chips that are present in everyday electronic devices. It is a multiple-step photolithographic and physio-chemical process during which electronic circuits are gradually created on a wafer, typically made of pure single-crystal semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications.

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit chips were developed and then widely adopted, enabling complex semiconductor and telecommunication technologies. The microprocessor and memory chips are VLSI devices.

Moore's law is the observation that the number of transistors in an integrated circuit (IC) doubles about every two years. Moore's law is an observation and projection of a historical trend. Rather than a law of physics, it is an empirical relationship linked to gains from experience in production.

Capital intensity is the amount of fixed or real capital present in relation to other factors of production, especially labor. At the level of either a production process or the aggregate economy, it may be estimated by the capital to labor ratio, such as from the points along a capital/labor isoquant.

Taiwan Semiconductor Manufacturing Company Limited is a Taiwanese multinational semiconductor contract manufacturing and design company. It is the world's second most valuable semiconductor company, the world's largest dedicated independent ("pure-play") semiconductor foundry, and its country's largest company, with headquarters and main operations located in the Hsinchu Science Park in Hsinchu, Taiwan. It is majority owned by foreign investors, and the central government of Taiwan is the largest shareholder.

The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits. It formed around 1960, once the fabrication of semiconductor devices became a viable business. The industry's annual semiconductor sales revenue has since grown to over $481 billion, as of 2018.

Fabless manufacturing is the design and sale of hardware devices and semiconductor chips while outsourcing their fabrication to a specialized manufacturer called a semiconductor foundry. These foundries are typically, but not exclusively, located in the United States, China, and Taiwan. Fabless companies can benefit from lower capital costs while concentrating their research and development resources on the end market. Some fabless companies and pure play foundries may offer integrated-circuit design services to third parties.

The 14 nm process refers to the MOSFET technology node that is the successor to the 22 nm node. The 14 nm was so named by the International Technology Roadmap for Semiconductors (ITRS). Until about 2011, the node following 22 nm was expected to be 16 nm. All 14 nm nodes use FinFET technology, a type of multi-gate MOSFET technology that is a non-planar evolution of planar silicon CMOS technology.

The term die shrink refers to the scaling of metal–oxide–semiconductor (MOS) devices. The act of shrinking a die creates a somewhat identical circuit using a more advanced fabrication process, usually involving an advance of lithographic nodes. This reduces overall costs for a chip company, as the absence of major architectural changes to the processor lowers research and development costs while at the same time allowing more processor dies to be manufactured on the same piece of silicon wafer, resulting in less cost per product sold.

Early in the twenty-first century, foreign investment as well as government regulations and incentives promoted growth in the Indian electronics industry. The semiconductor industry, which is its most important and resource-intensive sector, profited from the rapid growth in domestic demand. Many industries, including telecommunications, information technology, automotive, engineering, medical electronics, electricity and solar photovoltaic, defense and aerospace, consumer electronics, and appliances, required semiconductors. However, as of 2015, progress was threatened by the talent gap in the Indian sector, since 65 to 70 percent of the market was dependent on imports.
