... The materials whose conductivity and resistivity lies in between conductors and insulators are called semi - conducting materials. They have almost filled valence and empty conduction bands. They have small energy gap. Based on the current conducting property there are two types of semi- conductors. ...

... Since the energy gap for an insulator is large ( 10 eV) compared to kBT at room temperature (kBT = 0.025 eV at 300 K), the Fermi-Dirac distribution predicts that very few electrons will be thermally excited into the upper band at normal temperatures, as can be seen by the smaller value of fFD at the ...

Electron-beam lithography
Electron-beam lithography (often abbreviated as e-beam lithography) is the practice of scanning a focused beam of electrons to draw custom shapes on a surface covered with an electron-sensitive film called a resist (""exposing""). The electron beam changes the solubility of the resist, enabling selective removal of either the exposed or non-exposed regions of the resist by immersing it in a solvent (""developing""). The purpose, as with photolithography, is to create very small structures in the resist that can subsequently be transferred to the substrate material, often by etching.The primary advantage of electron-beam lithography is that it can draw custom patterns (direct-write) with sub-10 nm resolution. This form of maskless lithography has high resolution and low throughput, limiting its usage to photomask fabrication, low-volume production of semiconductor devices, and research & development.
