  2. Buffered oxide etch - Wikipedia

    en.wikipedia.org/wiki/Buffered_oxide_etch

    Buffered oxide etch (BOE), also known as buffered HF or BHF, is a wet etchant used in microfabrication. It is a mixture of a buffering agent , such as ammonium fluoride NH 4 F , and hydrofluoric acid (HF).

  3. Stone sealer - Wikipedia

    en.wikipedia.org/wiki/Stone_sealer

    The ancient Romans often used olive oil to seal their stone. Such treatment provides some protection by excluding water and other weathering agents, but it stains the stone permanently. During the renaissance Europeans experimented with the use of topical varnishes and sealants made from ingredients such as egg white, natural resins and silica ...

    en.wikipedia.org/wiki/Indium_tin_oxide

    Indium tin oxide (ITO) is an optoelectronic material that is applied widely in both research and industry. ITO can be used for many applications, such as flat-panel displays, smart windows, polymer-based electronics, thin film photovoltaics, glass doors of supermarket freezers, and architectural windows.

  7. Reactive-ion etching - Wikipedia

    en.wikipedia.org/wiki/Reactive-ion_etching

    Reactive-ion etching (RIE) is an etching technology used in microfabrication. RIE is a type of dry etching which has different characteristics than wet etching . RIE uses chemically reactive plasma to remove material deposited on wafers .

  8. Etching - Wikipedia

    ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the speed of the etching process. The etching process is known as biting (see also spit ...
