Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuits (ICs) such as computer processors, microcontrollers, and memory chips. It is a multiple-step photolithographic and physico-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.
In electronics, a wafer is a thin slice of semiconductor, such as a crystalline silicon, used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells.

The majority of TSMC is owned by foreign investors, and the central government of Taiwan is the largest shareholder. In 2023, the company was ranked 44th in the Forbes Global 2000.
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.
In semiconductor manufacturing, silicon on insulator (SOI) technology is fabrication of silicon semiconductor devices in a layered silicon–insulator–silicon substrate, to reduce parasitic capacitance within the device, thereby improving performance. SOI-based devices differ from conventional silicon-built devices in that the silicon junction is above an electrical insulator, typically silicon dioxide or sapphire. The choice of insulator depends largely on intended application, with sapphire being used for high-performance radio frequency (RF) and radiation-sensitive applications, and silicon dioxide for diminished short-channel effects in other microelectronics devices. The insulating layer and topmost silicon layer also vary widely with application.
Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in semiconductor device fabrication process. Examples include production of radio frequency (RF) amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer fabrication is used to build components with the necessary electrical structures.

The semiconductor industry, including Integrated Circuit (IC) manufacturing, design, and packaging, forms a major part of Taiwan's IT industry. Due to its strong capabilities in OEM wafer manufacturing and a complete industry supply chain, Taiwan has been able to distinguish itself as a leading microchip manufacturer and dominate the global marketplace. Taiwan’s semiconductor sector accounted for US$115 billion, around 20 percent of the global semiconductor industry. In sectors such as foundry operations, Taiwanese companies account for 50 percent of the world market, with Taiwan Semiconductor Manufacturing Company (TSMC) the biggest player in the foundry market.
The CHIPS and Science Act is a U.S. federal statute enacted by the 117th United States Congress and signed into law by President Joe Biden on August 9, 2022. The act authorizes roughly $280 billion in new funding to boost domestic research and manufacturing of semiconductors in the United States, for which it appropriates $52.7 billion. The act includes $39 billion in subsidies for chip manufacturing on U.S. soil along with 25% investment tax credits for costs of manufacturing equipment, and $13 billion for semiconductor research and workforce training, with the dual aim of strengthening American supply chain resilience and countering China. It also invests $174 billion in the overall ecosystem of public sector research in science and technology, advancing human spaceflight, quantum computing, materials science, biotechnology, experimental physics, research security, social and ethical considerations, workforce development and diversity, equity, and inclusion efforts at NASA, NSF, DOE, EDA, and NIST.
