  2. Wafer backgrinding - Wikipedia

    en.wikipedia.org/wiki/Wafer_backgrinding

    Wafer backgrinding is a semiconductor device fabrication step during which wafer thickness is reduced to allow stacking and high-density packaging of integrated circuits (IC). ICs are produced on semiconductor wafers that undergo a multitude of processing steps. The silicon wafers predominantly used today have diameters of 200 and 300 mm.

  3. Wafer testing - Wikipedia

    en.wikipedia.org/wiki/Wafer_testing

    Wafer testing is a step performed during semiconductor device fabrication after back end of line (BEOL) and before IC packaging.. Two types of testing are typically done. Very basic wafer parametric tests (WPT) are performed at a few locations on each wafer to ensure the wafer fabrication process has been carried out successfully.

    Wafer size has grown over time, from 25 mm (1 inch) in 1960, to 50 mm (2 inches) in 1969, 100 mm (4 inches) in 1976, 125 mm (5 inches) in 1981, 150 mm (6 inches) in 1983 and 200 mm in 1992. [41] [42] In the era of 2-inch wafers, these were handled manually using tweezers and held manually for the time required for a given process.

    en.wikipedia.org/wiki/Wafer-scale_integration

    Wafer-scale integration (WSI) is a system of building very-large integrated circuit (commonly called a "chip") networks from an entire silicon wafer to produce a single "super-chip". Combining large size and reduced packaging, WSI was expected to lead to dramatically reduced costs for some systems, notably massively parallel supercomputers but ...

  8. Etching (microfabrication) - Wikipedia

    en.wikipedia.org/wiki/Etching_(microfabrication)

    Etching is a critically important process module in fabrication, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography.

  9. 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
