The semiconductor process is the set of steps used to create an integrated circuit, also known as a microchip or chip. A single semiconductor process can produce a computer chip, or it can be used to produce a much smaller chip, such as a microprocessor. The semiconductor process involves many steps and is done in a cleanroom, where the air is filtered so that particles do not contaminate the semiconductor during the process.
The semiconductor manufacturing process has six major steps: semiconductor wafers fabrication, photolithography, etching, doping, assembly, and testing. Before a single transistor can be made, chip designers must take the specifications they need and turn them into a manufacturing-friendly file that can be used to create a photomask. Once the photomask is made, it is used in a photolithography process to transfer the pattern it contains to a silicon wafer. The next stage involves etching the pattern into the wafer using an etching process. In the diffusion process, the patterned silicon is infused with dopant chemicals to form the actual device. The final process is oxidation.
Semiconductor wafer fabrication
A semiconductor wafer fabrication is the process of creating devices from semiconductors, which is a material that has electrical conductivity properties that falls between that of a conductor, such as copper, and an insulator, such as glass. Semiconductor materials are the foundation of modern electronics, and they are the basis for processors, memory chips, transistors and other integrated circuits that make the iPhone and iPad work. There are several different types of semiconductor processes, and the one used depends on the device that is being created.
Photolithography
Photolithography is a technology that uses light to transfer an image onto a surface. Photolithography is used in the production of microchips. In fact, photolithography is the most commonly used semiconductor manufacturing technology. In the semiconductor industry, photolithography is utilized to transfer the image of an integrated circuit’s circuitry designed onto a silicon wafer.
Etching
The process is also used to manufacture microelectromechanical systems. An etcher is a tool used in photolithography to remove parts of a thin.
Ion Implantation
Ion implantation is a method of changing the properties of a target material through the introduction of energetic ions. In ion implantation, ions are accelerated by an electric field to high energies and then directed to a material surface. The ions impact the surface and release most of their kinetic energy to produce a range of effects, including alteration of the electronic structure, physical-mechanical effects like work hardening, and creation of defects.
