7 nm Process
In semiconductor manufacturing, the "7 nm" process is a term for the MOSFET technology node following the "10 nm" node, defined by the International Roadmap for Devices and Systems (IRDS), which was preceded by the International Technology Roadmap for Semiconductors (ITRS). It is based on FinFET (fin field-effect transistor) technology, a type of multi-gate MOSFET technology. As of 2021, the IRDS Lithography standard gives a table of dimensions for the "7 nm" node, with examples given below: The 2021 IRDS Lithography standard is a backward-facing document, as the first volume production of a "7 nm" branded process, as Taiwan Semiconductor Manufacturing Company (TSMC) began production of 256 Mbit SRAM memory chips using a "7 nm" process called N7 in June 2016, before Samsung began mass production of their "7 nm" process (7LPP) devices in 2018. These process nodes had the same approximate transistor density as Intel's "10 nm Enhanced Superfin" node, later rebran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semiconductor Manufacturing
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are present in everyday electrical and electronic devices. It is a multiple-step sequence of photolithographic and chemical processing steps (such as surface passivation, thermal oxidation, planar diffusion and junction isolation) during which electronic circuits are gradually created on a wafer made of pure semiconducting material. Silicon is almost always used, but various compound semiconductors are used for specialized applications. The entire manufacturing process takes time, from start to packaged chips ready for shipment, at least six to eight weeks (tape-out only, not including the circuit design) and is performed in highly specialized semiconductor fabrication plants, also called foundries or fabs. All fabrication takes place inside a c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epyc
Epyc is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture. Introduced in June 2017, they are specifically targeted for the server and embedded system markets. Epyc processors share the same microarchitecture as their regular desktop-grade counterparts, but have enterprise-grade features such as higher core counts, more PCI Express lanes, support for larger amounts of RAM, and larger cache memory. They also support multi-chip and dual-socket system configurations by using the Infinity Fabric interconnect. History In March 2017, AMD announced plans to re-enter the server market with a platform based on the Zen microarchitecture, codenamed Naples, and officially revealed it under the brand name Epyc in May. That June, AMD officially launched Epyc 7001 series processors, offering up to 32 cores per socket, and enabling performance that allowed Epyc to be competitive with the competing Intel Xeon product line. Two years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chandler, Arizona
Chandler is a city in Maricopa County, Arizona, United States, and a suburb in the Phoenix-Mesa-Chandler Metropolitan Statistical Area (MSA). It is bordered to the north and west by Tempe, to the north by Mesa, to the west by Phoenix, to the south by the Gila River Indian Community, and to the east by Gilbert. As of the 2020 census, the population of Chandler was 275,987, up from 236,123 at the 2010 census. History In 1891, Dr. Alexander John Chandler, the first veterinary surgeon in Arizona Territory, settled on a ranch south of Mesa, studying irrigation engineering. By 1900, he had acquired of land, and began drawing up plans for a townsite on what was then known as the Chandler Ranch. The townsite office opened on May 16, 1912. (Soon after celebrating Chandler's Centennial on May 17, 2012, Chandler Museum staff discovered that the city had been celebrating the wrong date. In May 1912, the ''Chandler Arizonan'' newspaper had erroneously published the founding day as Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extreme Ultraviolet Lithography
Extreme ultraviolet lithography (also known as EUV or EUVL) is an optical lithography technology used in steppers, machines that make integrated circuits (ICs) for computers and other electronic devices. It uses a range of extreme ultraviolet (EUV) wavelengths, roughly spanning a 2% FWHM bandwidth about 13.5 nm, to produce a pattern by exposing reflective photomask to UV light which gets reflected onto a substrate covered by photoresist. It is widely applied in semiconductor device fabrication process. As of 2022, ASML Holding is the only company who produces and sells EUV systems for chip production, targeting 5 nm and 3 nm. At the 2019 International Electron Devices Meeting (IEDM), TSMC reported use of EUV for 5 nm in contact, via, metal line, and cut layers, where the cuts can be applied to fins, gates or metal lines. At IEDM 2020, TSMC reported their 5 nm minimum metal pitch to be reduced 30% from that of 7 nm, which was 40 nm. Samsung's 5&nbs ...

Static Random-access Memory
Static random-access memory (static RAM or SRAM) is a type of random-access memory (RAM) that uses latching circuitry (flip-flop) to store each bit. SRAM is volatile memory; data is lost when power is removed. The term ''static'' differentiates SRAM from DRAM (''dynamic'' random-access memory) — SRAM will hold its data permanently in the presence of power, while data in DRAM decays in seconds and thus must be periodically refreshed. SRAM is faster than DRAM but it is more expensive in terms of silicon area and cost; it is typically used for the cache and internal registers of a CPU while DRAM is used for a computer's main memory. History Semiconductor bipolar SRAM was invented in 1963 by Robert Norman at Fairchild Semiconductor. MOS SRAM was invented in 1964 by John Schmidt at Fairchild Semiconductor. It was a 64-bit MOS p-channel SRAM. The SRAM was the main driver behind any new CMOS-based technology fabrication process since 1959 when CMOS was invented. In 1965 ...

5 nm
In semiconductor manufacturing, the International Roadmap for Devices and Systems defines the 5 nm process as the MOSFET technology node following the 7 nm node. In 2020, Samsung and TSMC entered volume production of 5 nm chips, manufactured for companies including Apple, Marvell, Huawei and Qualcomm. The term "5 nanometer" has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors. According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a 5 nm node is expected to have a contacted gate pitch of 51 nanometers and a tightest metal pitch of 30 nanometers. However, in real world commercial practice, "5 nm" is used primarily as a marketing term by individual microchip manufacturers to refer to a new, improved generation of silicon semiconductor chips in terms of increased transistor density (i.e. a ...

Silicon-on-insulator
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 (these types of devices are called silicon on sapphire, or SOS). 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. Industry need SOI technology is one of several manufacturing strategies to allow the continued miniaturization of microelectronic devices, colloquially referred to a ...
