  2. Wafer fabrication - Wikipedia

    en.wikipedia.org/wiki/Wafer_fabrication

    Wafer fabrication is a procedure composed of many repeated sequential processes to produce complete electrical or photonic circuits on semiconductor wafers in a semiconductor device fabrication process. Examples include production of radio frequency amplifiers, LEDs, optical computer components, and microprocessors for computers. Wafer ...

  3. Wafer (electronics) - Wikipedia

    en.wikipedia.org/wiki/Wafer_(electronics)

    In electronics, a wafer (also called a slice or substrate) [1] is a thin slice of semiconductor, such as a crystalline silicon (c-Si, silicium), used for the fabrication of integrated circuits and, in photovoltaics, to manufacture solar cells. The wafer serves as the substrate for microelectronic devices built in and upon

  4. Semiconductor device fabrication - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_device...

    A recipe in semiconductor manufacturing is a list of conditions under which a wafer will be processed by a particular machine in a processing step during manufacturing. [158] Process variability is a challenge in semiconductor processing, in which wafers are not processed evenly or the quality or effectiveness of processes carried out on a ...

  5. wafer-to-wafer (also wafer-on-wafer) stacking – bonding and integrating whole processed wafers atop one another before dicing the stack into dies wire bonding – using tiny wires to interconnect an IC or other semiconductor device with its package (see also thermocompression bonding, flip chip, hybrid bonding, etc.)

  6. Semiconductor fabrication plant - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_fabrication...

    In the microelectronics industry, a semiconductor fabrication plant, also called a fab or a foundry, is a factory where integrated circuits (ICs) are manufactured. [1]The cleanroom is where all fabrication takes place and contains the machinery for integrated circuit production such as steppers and/or scanners for photolithography, etching, cleaning, and doping.

  7. Die preparation - Wikipedia

    en.wikipedia.org/wiki/Die_preparation

    Wafer mounting is a step that is performed during the die preparation of a wafer as part of the process of semiconductor fabrication. During this step, the wafer is mounted on a plastic tape that is attached to a ring. Wafer mounting is performed right before the wafer is cut into separate dies. The adhesive film upon which the wafer is mounted ...

  8. Stepper - Wikipedia

    en.wikipedia.org/wiki/Stepper

    Once the wafer and reticle are in place and aligned, the wafer stage, which is moved very precisely in the X and Y directions (front to back and left to right) by worm screws or linear motors, carries the wafer so that the first of the many patterns (or "shots") to be exposed on it is located below the lens, directly under the reticle.

  9. Microfabrication - Wikipedia

    en.wikipedia.org/wiki/Microfabrication

    Simplified illustration of the process of fabrication of a CMOS inverter on p-type substrate in semiconductor microfabrication. Each etch step is detailed in the following image. The diagrams are not to scale, as in real devices, the gate, source, and drain contacts are not normally located in the same plane. Detail of an etch step.
