rayleigh equation, resolution enhancement, process difficulty, lithography k1, multi-patterning
The k1 factor is the single number in the Rayleigh resolution equation that measures how hard a lithography process is being pushed relative to the physical limit of its own…
metrology
Kelvin Contact (Four-Terminal Sensing) is the precision resistance measurement technique that eliminates probe contact resistance and lead resistance errors by using separate…
metrology
A Kelvin probe measures contact potential difference (CPD)—the electrostatic potential between a vibrating probe tip and a sample surface—via an AC capacitive coupling…
kelvin probe force microscopy, kpfm, metrology
Kelvin Probe Force Microscopy (KPFM) is a scanning probe technique that measures the local contact potential difference (CPD) between a conductive AFM tip and a sample surface…
wafer dicing, scribe street width, blade dicing, laser dicing, plasma dicing, die per wafer, singulation
Kerf loss is the silicon area destroyed, not just divided, when a wafer gets cut into individual die — the width of material the saw blade, laser, or plasma stream actually…
metrology
Killer defect size is the minimum defect dimension that causes device failure — a critical threshold that determines inspection sensitivity requirements, with smaller nodes…
kgd, advanced packaging
Known Good Die (KGD) is a semiconductor die that has been fully tested and verified to be functional before being assembled into a multi-die package — ensuring that only working…
anisotropic silicon etching, wet etch silicon, potassium hydroxide etch, mems bulk micromachining, crystal plane etch, koh silicon etch, crystallographic etch, v groove etch

krf, krypton fluoride, lithography
KrF (krypton fluoride) excimer lasers produce 248nm deep-UV light, and were the industry's workhorse exposure source from roughly 1996 to 2005 — carrying the transition…
krf lithography, what is krf lithography
KrF lithography uses krypton-fluoride excimer-laser light to expose photoresist. Its nominal wavelength is 248 nanometers, within deep ultraviolet. The laser is part of a larger…
