BOE 7:1
Buffered Oxide Etch
General Information
BOE is mainly used for etching glasses, quartz and SiO2 films.
We supply BOE 7:1 = buffered hydrofluoric acid (HF : NH4F = 12.5 : 87.5%) in VLSI-quality, which is the usual purity grades applied in semiconductor processing and micro-electronics.
NOTE:
BOE must be stored and transported above +12.5°C. Below this critical temperature of 12.5°C the material forms particles (little crystals). Since these crystals have a higher density, they will accumulate at the bottom of the bottle and will only be completely re-dissolved when the material is stored at temperatures of 30 - 35°C for some days. After this procedure the crystals should be re-dissolved completely and the BOE can be then used without restrictions.

Hydrochloric Acid 37% - 2.50 l - VLSI - EVE/EUD!
HHCV1025
Hydrochloric Acid
HCI
General Information
Hydrochloric Acid is an ingredient of various etching mixtures for e.g. ITO, Silver and (together with HNO3 as aqua regia) gold. HCl is suited for the removal of oxide films on many metals.
Our Hydrochloric Acid (37%) is available in VLSI-quality, which is the usual purity grades applied in semiconductor processing and micro-electronics.
NOTE:
HCl (hydrogen chloride), is a gas that dissolves very well in water and forms hydrochloric acid in dissolved form. With a molar mass of 36 g / mol, hydrogen chloride is a very small molecule, which means that it can diffuse through polymers very well. For reasons of purity, the hydrochloric acid is filled in HD-PE polymer bottles. In order to protect the bottles from particles and contaminations, these bottles (which are intended for the use in clean rooms) are packed in plastic bags. Over the time of storage, however, the hydrogen chloride diffuses through the wall of the bottle, which is made of polymer, and collects in the foil bag. There is air that contains not only carbon dioxide but also water vapor and it can react with the hydrogen chloride, whereby either a white dust or fine droplets can be found in the foil bag. This happens during storage even if there is not the slightest leak in the bottles. This white dust or the possible fine droplets are the reason why the 37% hydrochlo¬ric acid, unlike e.g. sulfuric acid of the same degree of purity, has not a shelf life of 3 years, but is only „durable“ for 1 year. It is therefore not the reason that the acid would not maintain its purity or its properties, but rather the label and also the bottles or foil bags are increasingly affected by the problem described above in the course of storage.
