Low k vs high k

In integrated circuits, and CMOS devices, silicon dioxide can readily be formed on surfaces of Si through thermal oxidation, and can further be deposited on the surfaces of conductors using chemical vapor deposition or various other thin film fabrication methods. Due to the wide range of methods that can be used to cheaply form silicon dioxide layers, this material is used conventionally as the baseline to which other low permittivity dielectrics are compared. The relat… Web22 mei 2024 · Figure 3. (a) Schematic diagram of a parallel-plate metal–insulator–metal (MIM) capacitor. (b) Comparison of the frequency-dependent areal capacitance of high-k and low-k dielectric films.

WebKinetics: 6.32 - The rate constant. Significance of the rate constant. The rate constant, k, gives a direct measure of the relative reaction rate. A very small value for the rate constant equates to a very slow reaction in general. Equally, a large value for the rate constant means a large value for the rate and that the reaction is rapid.
