a hf/h20 vapor etching of sio2 sacrificial layer for large-area surface-micromachined membranes An HF/H2O 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 ...
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...

依据化学方程式说明(如图12)，HF和SiO2反应会生成氟化硅(SiF4)，在水中会水解生成氟化硅和氟酸，氟化硅与氟酸生成氟硅酸(六氟硅酸)，六氟硅酸可溶于水纯H2SiF6不稳定，容易分解生成HF和SiF4。由GPTC二强实验数据(如图12)得知H2SiF6的增加会影响蚀刻速率(EtchingRate;ER)的下降，因此化学二次强化制程除了定时监控...
HF etching mechanism of heavily doped Si. 来自 lirias.kuleuven.be 喜欢 0 阅读量: 128 作者: N Valckx 摘要: In solid-state device processing, cleaning of the substrates has always attracted a lot of interest, so also the cleaning of Si and the removal of SiO2 by HF solutions. HF is a...

Marvel not therefore, the surprise when etching by HF concentrated aqueous solutions of thermally grown SiO2 was discovered to leave hydrogen-terminated silicon surfaces [9]. The first explanation of this fact was in terms of polarization of Si–Si back-bonds to Si–F bonds. Assuming that the ...
