Glossary

Term Definition
KGD Known Good Die — bare unpackaged die that has been tested and verified to meet all electrical and reliability specifications prior to assembly into a multi-chip module or package.
MCM Multi-Chip Module — module containing multiple unpackaged ICs (dice) mounted on a common substrate, interconnected bywire bonds or flip-chip bumps, providing higher density and performance than single-chip packages.
LTCC Low-Temperature Co-Fired Ceramic — ceramic substrate technology fired at ~850°C, allowing gold or copper conductors and buried passive components. Well-suited for RF/microwave and high-reliability applications.
HTCC High-Temperature Co-Fired Ceramic — ceramic substrate technology fired at ~1650°C, typically using molybdenum or tungsten metallization. Used for high-power and high-temperature applications.
Thick Film Thick film technology — screen-printed conductor and dielectric pastes fired at 850–1000°C on ceramic substrate. Conductors typically gold (Au) or copper (Cu). Used for RF and power hybrid circuits.
Thin Film Thin film technology — physical or chemical vapor deposition (PVD/CVD) of thin metal layers on ceramic substrate. Provides precise line widths, tight tolerances, and superior RF performance for microwave and mmWave circuits.
Hermetic Hermetic seal — airtight sealing of a cavity or package preventing moisture and gas ingress. Hermetic packages are required for long-life aerospace, defense, and some medical applications. Typical leak rate: <1×10⁻⁸ atm·cm³/s (fine leak).
C-SAM Scanning Acoustic Microscopy — nondestructive inspection technique using ultrasonic waves to detect delaminations, voids, cracks, and moisture ingress in packaged devices and multi-layer substrates. Essential for hybrid assembly QC.
PIND Particle Impact Noise Detection (MIL-STD-883 Method 1015) — test to detect loose particles inside hermetic packages by vibrating the package and detecting particle impacts with a piezoelectric transducer.
HTOL High-Temperature Operating Life — accelerated reliability test subjecting devices to elevated temperature (typically 125–150°C) with bias applied, used to extrapolate failure rate and infant mortality for ICs and hybrids.
HAST Highly Accelerated Stress Test — unbiased moisture resistance test using high temperature (85–110°C) and high humidity (85% RH) to accelerate moisture ingress and identify package delamination risks.
THB Temperature-Humidity-Bias — test applying simultaneous temperature, humidity, and electrical bias to evaluate device reliability under humid operating conditions. Used for automotive and industrial applications.
ELFR Early Life Failure Rate — measure of infant mortality failures occurring within the first several thousand hours of device operation. Qualifying to ELFR targets requires HTOL or similar burn-in testing per JESD47.
DFMEA Design Failure Mode and Effects Analysis — systematic reliability analysis method identifying potential failure modes in a design, their causes, effects, and severity, used to drive design improvements and risk reduction.
FIT Rate Failures In Time — unit representing one failure per billion device-hours. Used to express failure rate of components and modules. A FIT rate of 100 = 0.01% per 1000 hours at 40°C junction temperature.
DPM Defects Per Million — metric used to express manufacturing defect density in assembled modules. DPM targets vary by industry: defense/space typically <10 DPM; automotive typically <100 DPM; commercial up to 1000 DPM.
TID Total Ionizing Dose — radiation hardness parameter measuring cumulative ionizing radiation exposure (measured in krad or rad) that causes parametric degradation in semiconductor devices. Critical for space applications.
Kovar FeNiCo alloy (nominal composition: 29% Ni, 17% Co, 54% Fe) with thermal expansion coefficient matched to borosilicate glass (~5.9 ppm/°C). Used for hermetic package leadframes and feedthroughs.
AuSn Gold-Tin eutectic solder alloy (80% Au, 20% Sn) with melting point of 278°C. Widely used for die attach in high-reliability and high-temperature hybrid applications due to high shear strength and thermal conductivity.
Eutectic Die Attach Die attach using a eutectic bonding process, typically AuSi (gold-silicon, 363°C melt) or AuGe (gold-germanium, 356°C melt). Creates a metallurgical bond between die back side and substrate metallization without organic outgassing.
Conformal Coating Protective dielectric coating (acrylic, urethane, silicone, or parylene) applied over assembled circuit boards and hybrids to protect against moisture, dust, chemicals, and mechanical vibration. Not used on hermetic packages.
