I had spent the night before taking a rickety boat across the dark Nile, under a dusky moon, to the rocky island of Philae, where Isis' temple loomed eerily under spotlights, images of the powerful goddess etched over and over high on the walls, her eagle wings spread in triumph.
This greatly reduced the required Al mask thickness from over 500 to 100 nm for a deep silica etch of over 5 μm, and leaded to the achievement of high-quality silica waveguides with vertical and very smooth sidewalls.
He had roses etched over the barbed wire.
But then it dissolved in a little satin top with chiffon etched over the shoulders.
"I felt good today, better than I was expecting for not being on the ice for a couple days, so that's encouraging," McDonagh said as he sat at his dressing-room stall here, 12 stitches newly etched over his upper lip.
A comparison of different approaches for resist plasma removal (ashing) after dielectric-etch, over a porous spin-on methylsilsequioxane (MSQ) based dielectric material with a k value of 2.2 (here after designed as ULK, for ultra low dielectric constant) was conducted.
In the case of the demonstrator module, ICVs are etched over the original wire bonding pads of the FE-I3 chip.
Small-diameter SWNTs were preferentially etched over larger ones because of the higher radius curvature and strain in the C-C bonding.
A perfluoropolymer cladding layer is added to the entire chip surface via spin coating, and annular windows are etched over 132 of 136 rings.
Notice the different patterns and paths etched over the material creating tiny metallic "islands".
These factors result in a gradually decreasing etch rate over time, with re-nucleated Ag-catalyzed etching being dominant for low χ values and impeded diffusion being more pronounced for high χ values.
