According to the mechanism of HF etching SiO2 and SiNx:H,the over-plating phenomenon of multicrystalline silicon solar cells was improved by adjusting the pH value of the buffer HF solution.%自对准的光诱导化学镀/电镀技术以其栅线宽度小,工艺快捷高效等优点,成为制备选择性发射极太阳能电池的理想选择...
An HF/HO vapor etching technique has been applied as a sacrificial oxide etching process step in surface-micromachining technology. This technique does not suffer from the notorious problem known as stiction, i.e., permanent attachment of movable structures to the underlying substrate during drying ...
Etching Mechanism of Silicon Nitride in HF-Based Solutions A reaction mechanism for the etching of silicon nitride layers in aqueous hydrofluoric acid solutions is proposed. The surface of Si3N4 Si3N4 consists of... D Martin Knotter,(Dee) Denteneer, T. J. J. - 《Journal of the Electroche...
Silicon dioxide ( Si O 2 ) films grown on single crystal Si in high temperature O 2 were etched using nonaqueous HF/pyridine solutions in supercritical C O 2 . The etch rate of Si O 2 films were studied in the solutions with HF concentration up to 1000 渭 M at 1.38 脳 10 7 Pa ...
According to the mechanism of HF etching SiO and SiNx:H, 2 2 the over-plating phenomenon of multicrystalline silicon solar cells was improved by adjusting the pH value of the buffer HF solution. Keywords over-plating; selective etching; light-induced electroless plating/electro-plating; multi...
Anisotropic etching of SiO2 film and quartz plate employing anhydrous HF (AHF) was studied. In this etching, neither plasma nor ultraviolet light was used. A SiO2 film below the photoresist, OFPR-800, was selectively etched with AHF gas. However, etch-stop was observed at the depth of 1.5...
(PR) film is subsequently deposited by spin coating. Once employing photolithography to create the required pattern on the PR, the PR photo-mask is entirely removed once the Si3N4etching barrier has been selectively etched using the buffered hydrofluoric (HF) acid etchant. The ideal V-shaped ...
The local mechanisms of dissociative chemisorption and reactive etching are investigated by molecular models modeling SiOH groups and SiOSi bridges at SiO 2 surfaces. The elementary reaction paths for the reactions of HF and HCl with Si O bonds of the models, Si(OH) 4 and (HO) 3 SiOSi(OH...
Notwithstanding these issues, because the estimated ERR falls closely below the G-G interfacial energy, we are confident of the mechanism whereby the G/G interface between SiO2 and Ni is the weakest interface when multilayer graphene is present. This conclu- sion is supported by the observation ...
