TMAH chemical etch rate at ambient temperature is sensitive to environmental conditions. Increase N_2 concentration in chemical would reduce O_2 partial pressure and leads to higher poly etching rate. Other gas such as CO_2 have the opposite effect and makes ER trend down to zero, probably ...

The conditions of the plasma were: 100W RF power, with 20sccm flow of gas, 100 mtorr pressure and 4 minutes of plasma attack.After oxygen plasma attack, PVK film thicknesses had been measured by ALPHA STEP 500 profilometer. PVK film corrosion rate was measured as a function of the oxygen...
In this process, lithographic patterning and wet chemical etching of silicon are used to produce a master mold. The silicon wafers are silanized in 3% (v/v) dimethyloctadecylchlorosilane in toluene for 2 h to facilitate peeling off the PDMS replica. A 10:1 mixture of PDMS base and its ...
High-K meta gate process is widely used at nodes of 28nm and below, because of low power consumption and lower leakage In gate first high-k metal gate process, there is a need to remove dummy grid poly- silicon by wet etch and stop on work function metal ...
Wet-etching methods can lower fabrication cost compared to dry etching, but the geometry of microneedles is restricted by anisotropic etching along crystal planes by the KOH etchant [57]. To overcome this limit of wet etching, isotropic dry etching and anisotropic wet etching methods have been ...

The thin films of metal were removed using a potassium iodide (KI) based wet etch (AU-5) for the evaporated gold thin films and a ceric ammonium nitrate (NH4)2Ce(NO3)6 and concentrated perchloric acid (HClO4) based wet etch (CR-7) for the evaporated chromium thin films64. For a ...
As shown in Fig. 3a, the redox peak of the triphenylamine unit of PTPAT is enhanced with increasing the scan rate within the potential range from 0.4 to 1.2 V. As expected for a surface-bound couple, the anodic and cathodic peak currents are linear with the scan rate (Fig. 3b...
Using mask 72, dielectric regions 67d are removed, preferably by a mild dip etch or other form of isotropic selective etching, so as to produce the structure shown in FIG. 3E. The process illustrated in FIGS. 3A-E produces hole 81 having substantially straight sides, i.e., edges 63e ...
