A compound semiconductor is a semiconductor compound composed of chemical elements of at least two different species. These semiconductors form for example in periodic table groups 13–15 (old groups III–V), for example of elements from the Boron group (old group III, boron, aluminium, gallium, indium) and from group 15 (old group V, nitrogen, phosphorus, arsenic, antimony, bismuth).
The various metal layers are interconnected by etching holes (called "vias") in the insulating material and then depositing tungsten in them with a CVD technique using tungsten hexafluoride; this approach can still be (and often is) used in the fabrication of many memory chips such as dynamic random-access memory (DRAM), because the number of ...
Liquidmetal has also notably been used for making the SIM ejector tool of some iPhone 3Gs made by Apple Inc., shipped in the US. This was done by Apple as an exercise to test the viability of usage of the metal. [11] They retain a scratch-free surface longer than competing materials, while still being made in complex shapes.
The Biden administration later upped the ante and introduced export control measures in October 2022 that curbed the sale of advanced chips or chipmaking equipment to China without permission.

An integrated circuit (IC), also known as a microchip or simply chip, is a set of electronic circuits, consisting of various electronic components (such as transistors, resistors, and capacitors) and their interconnections.

FeRAM was commercialized in the mid-1990s. In 1994, video game company Sega used FeRAM chips to store saved games in Sonic the Hedgehog 3, which shipped several million game cartridges that year. [9] In 1996, Samsung Electronics introduced a 4 Mb FeRAM chip fabricated using NMOS logic. [10]
China's Commerce Ministry announced Thursday that it will restrict exports of a mineral used in a wide range of products from batteries to weapons. Export controls will be placed on antimony ...
The MOSFET is the most widely used type of transistor and the most critical device component in integrated circuit (IC) chips. [2] Planar process, developed by Jean Hoerni at Fairchild Semiconductor in early 1959, was critical to the invention of the monolithic integrated circuit chip by Robert Noyce later in 1959.
