Crystal originated particle
WebTo observe the effects of crystal-originated-particle (COP), vacancy-rich wafers and COP-free wafers were compared. In breakdown voltage (BV) measurement, breakdown fractions of vacancy-rich wafers were increased with the increase of oxide thickness (tOX) and showed a maximum value at the tOX range of 10–20nm. On the other hand, COP-free WebApr 27, 2008 · Abstract: The effects of crystal-originated particles (COPs) on ultra-thin gate oxide for recent ultra large-scale integration (ULSI) devices were studied.

WebCOP stands for Crystal Originated Particle. One of the various silicon wafer surface defects. Their basic micro structure is octahedral void shape with the size of sub-micron scale. WebJul 8, 2008 · Since the epitaxial layer of an epi-wafer does not contain grown-in defects due to silicon crystal growth processes such as crystal originated particle (COP) and resulting microprecipitates [ 4, 5 ], one can eliminate quite effectively device failures induced by these types of crystal defects.
WebOct 1, 1997 · To clarify the influence of crystal-originated "particles" (COPs) on gate oxide integrity (GOI), a new GOI evaluation method has been developed. This method compares the GOI of a metal oxide silicon (MOS) capacitor which includes a COP with a MOS capacitor that is COP-free by measuring the capacitors' I–V characteristics.

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.
WebSep 27, 2024 · Crystal-originated particle (COP) side-wall angles and rates of change in width were measured after treatment in an SC-1 solution by atomic force microscopy (AFM) to determine the shape, size and type of the particles on a polished (100) Si wafer surface. The etched silicon tip’s maximum measurable slope angles were used to determine …
