Physical effect of electronic bombardment in the target. Electron-beam (e-beam) lithography is a lithographic process used to transfer circuit patterns onto silicon or other substrates. However, EBL resolution has been limited to 4 nm isolated features and 16 nm periodic structures. Electron-beam lithography (EBL) was first reported as a technique for patterning substrate materials as early as the 1960s, 148,149 and has been used for patterning nano to micron-scale features for cell studies for the past 20 years. There are several forms of lithography, such as photolithography, which uses UV light to expose the design pattern on the wafer surface. The demand for fine patterns calls for EBL systems with high acceleration voltages. We report on the hydrogen gas (H2) sensing performance of lithographically patterned Pd nanowires as a function of the nanowire thickness and H2 concentration.
