Crystal originated particle
WebCharacterization of Si wafers by delineation of crystal originated particles (COP) provides insight into size and radi- al distribution of crystal related defects. A good correlation of the COP densities with gate oxide integrity and flow pat- tern defect densities is observed. WebSep 7, 2024 · Lattice vibrations can explain sound velocity, thermal properties, elastic properties and optical properties of materials. Lattice Vibration is the oscillations of atoms in a solid about the equilibrium position. For a crystal, the equilibrium positions form a regular lattice, due to the fact that the atoms are bound to neighboring atoms.
