5.2 Terminology Regarding Defect Type
5.2.1 COP (C
rystal Originated Particle/Pit) — A pit
of approximately 100 nm in size bounded by
crystallographic planes, and formed by the intersection
of the polished surface with voids in the crystal.
5.2.1.1 Discussion — When the surface is cleaned,
etched, or oxidized the shape of the pit is modified and
the light scattering characteristics change. The spatial
distribution of scattered light from COPs and particles
is different, and therefore these two classes of defects
may be distinguished by an appropriately equipped
SSIS. COPs were first detected by SSIS and believed
to be small particles. It was also noticed that after
repeated cleaning (etching) the number of the COPs
increased as the etching process enlarged the pits and
changed their scattering characteristics. Later these
defects were identified as voids caused by the
coalescence of vacancies during the cooling of the
silicon crystal from its growth temperature. The term
crystal originated particle had already become accepted,
and even today many people still refer to COPs by their
original, though incorrect name.

5.2.2 dimple — a shallow depression with gently
sloping sides that exhibits a concave, spherical shape
and is visible to the unaided eye under proper lighting
conditions. [SEMI M1]
5.2.3 haze — non-localized light scattering resulting
from surface topography (microroughness) or from
dense concentrations of surface or near surface
imperfections. [SEMI M1]
5.2.4 mound (epitaxial wafer) — regularly shaped
bump on a semiconductor wafer surface, which may
have one or more irregularly developed facets. [ASTM
F 1241]
5.2.5 mound (polished wafer) — a defect characterized
by small circular raised areas on the surface, typically
0.1 to 1.0 µm in height, 5 to 25 mm in diameter and
located in random positions on the wafer.
5.2.6 particle — a small, discrete piece of foreign
material or silicon not connected crystallographically to
the wafer. [SEMI M1]
5.2.7 pit — a depression in a wafer surface that has
steeply sloped sides that meet the surface in a
distinguishable manner in contrast to the rounded sides
of a dimple. [SEMATECH Technology Transfer
95082941A-TR]
5.2.8 scratch —
a shallow groove or cut below the
established plane of the wafer surface, with a length to
width ratio greater than 5:1. [SEMATECH Technology
Transfer 95082941A-TR
5.2.9 slip — a process of plastic deformation in which
one part of a crystal undergoes a shear displacement
relative to another in a fashion that preserves the
crystallinity of the material. [ASTM F 1241]
5.2.10 slurry ring — a ring-shaped area, higher than
the surrounding wafer surface caused by incomplete
cleaning of slurry residue.
5.2.11 spike — in an epitaxial wafer, a tall thin
dendrite of crystalline filament that often occurs at the
center of a recess. [ASTM F 1241, see also ASTM F
154]
5.2.12 stacking fault —
a two dimensional defect that
results from a deviation from the normal stacking
sequence of atoms in a crystal. [ASTM F 1241, see also
ASTM F 154]
5.2.13 stain — area contamination that is chemical in
nature and cannot be removed except through further
lapping or polishing. [ASTM F 1241]
5.3 Other Terminology
5.3.1 bias — the difference between the average of
measurements made on the same object and its true
value. Sufficient measurements are needed to mitigate
the effects of variability. [SEMI E89]
5.3.2 calibration — a measurement process that
assigns a value to the property of an artifact or to the
response of an instrument relative to reference
standards or to a designated measurement process.
5.3.2.1 Discussion — The purpose of calibration is to
eliminate or reduce bias in the user’s measurement
system relative to the reference base. The calibration
process compares an unknown or test item or
instrument with reference standards according to a
specific algorithm, often in the form of a specific
calibration curve. [SEMI
E89]
5.3.3 capture rate — the probability that an SSIS
detects an LLS of latex sphere equivalent (LSE) signal
value at some specified SSIS operational setting.
5.3.4 classification accuracy — how many of a
particular defect population are correctly classified.
5.3.4.1 Discussion — The accuracy of a classification
system is expressed as an equation: Accuracy = A/H,
where A is the total quantity of correctly classified
defects (human and machine classification results
agree) and H is the total quantity of human classified
defects.
5.3.5 classification purity — how many of the defects
classified by machine (SSIS) are properly classified.
5.3.5.1 Discussion — The purity of a classification
system can be expressed as an equation: Purity = A/M,
where A is the total quantity of correctly classified
defects (human and machine classification results
agree) and M is the total quantity of defects classified
as a specific class by machine (SSIS).
5.3.6 compatibility — the capability of measurement
equipment to emulate the measurement process of other
tools. Downward compatibility refers to former
generation(s) of the same or similar type of equipment
of an equipment supplier.
5.3.7 correlation — the relation of measurement
results obtained by repeated measurements with the
same set of test specimen(s) and any two measurement
tools expressed in terms of a regression curve.
5.3.8 CRM (Certified Reference Material) — reference
material, accompanied by a certificate, one or more of
whose property values are certified by a procedure
which establishes its traceability to an accurate
realization of the unit in which the property values are
expressed, and for which each certified value is
accompanied by an uncertainty at a stated level of
confidence. [ISO Guide 30:1992]
