What does a wafer fab technician do?
As a wafer fab operator, you are responsible for performing fabrication or electrical wafer test operations. You set up, operate, load, and monitor a machine and equipment to inspect/verify the quality of the product that is produced. You are responsible for recording and analyzing data.
What is a fabrication technician?
Fabrication technicians are skilled employees who are responsible for using specialized equipment to assemble components for a variety of products or finished products. These technicians are required to perform inspections on the tools and mechanical equipment as well as provide maintenance and repair.
What is wafer fab engineer?
Wafer fabrication engineers are responsible for developing, testing, documenting, and improving the production process in wafer fabrication. They select and install equipment, set specifications, and work with technicians to ensure the process is effective and efficient.
How wafers are fabricated?
The silicon wafers start out blank and pure. The circuits are built in layers in clean rooms. First, photoresist patterns are photo-masked in micrometer detail onto the wafers’ surface. The wafers are then exposed to short-wave ultraviolet light and the unexposed areas are thus etched away and cleaned.
What is a wafer technician?
A wafer fab technician performs daily maintenance and upkeep of facilities and production equipment necessary for wafer fabrication. You may work with silicon wafers. Other responsibilities include running technical tests and experiments, performing and documenting test runs, and charting results.
Which is a semiconductor?
Semiconductors. Semiconductors are materials which have a conductivity between conductors (generally metals) and nonconductors or insulators (such as most ceramics). Semiconductors can be pure elements, such as silicon or germanium, or compounds such as gallium arsenide or cadmium selenide.
What are the types of fabrication?
Cutting, punching, forming, shearing, stamping, welding are common fabrication techniques used to shape, cut, or mold raw metal material into a final product. Fabrication is distinct from other manufacturing processes.
What does a fabrication specialist do?
A fabrication specialist manufactures component parts from metal or other industrial materials. You can find fabrication specialist jobs in the aerospace, automotive, and electronics industries.
WHAT IS wafer technology?
A wafer is a piece of silicon (one of the most abundant semiconductors available worldwide) or other semiconductor material, designed in the form of a very thin disc. Wafers are used to create electronic integrated circuits (ICs) and silicon-based photovoltaic cells.
How long does it take to fabricate a wafer?
Here’s why: manufacturing a finished semiconductor wafer, known as the cycle time, takes about 12 weeks on average but can take up to 14-20 weeks for advanced processes. To perfect the fabrication process of a chip to ramp-up production yields and volumes takes even much more time – around 24 weeks.
How many steps are involved in processing a wafer?
Introduction. The manufacture of each semiconductor components products requires hundreds of processes. After sorting, the entire manufacturing process is divided into eight steps: Wafer Processing, Oxidation, Photography, Etching, Film Deposition, Interconnection, Test, and Package.
What are the 6 semiconductors?
The elemental semiconductors are those composed of single species of atoms, such as silicon (Si), germanium (Ge), and tin (Sn) in column IV and selenium (Se) and tellurium (Te) in column VI of the periodic table. There are, however, numerous compound semiconductors, which are composed of two or more elements.
