PLD, user-configurable logic, PAL CPLD FPGA, custom logic without custom chip, reconfigurable chip
A programmable logic device is a chip whose logic function can be configured by the user after manufacture, rather than being fixed when the chip is made, giving designers a way…
projection lithography, photolithography, mask projection, contact printing replacement, wafer exposure
A projection aligner is a photolithography machine that transfers a mask pattern onto a wafer by projecting an image of the mask through a lens system onto the wafer's surface…
proximity lithography, mask gap, contact printing, diffraction limit, shadow printing
Proximity printing is a photolithography method in which the mask is held a small distance above the wafer during exposure rather than pressed directly against it, a compromise…

Ptychography is a computational imaging technique that recovers both the amplitude and phase of a transmitted wave by scanning a coherent probe across overlapping positions…
off axis illumination lithography, source mask optimization, dipole quadrupole illumination
Pupil Fill and Illumination Source Shape A lithography scanner's illumination doesn't have to fill its pupil uniformly, and for anything near the resolution limit, it shouldn't.…
semiconductor purity, nine nines, 9N purity, electronic-grade polysilicon, Siemens process, ultrapure water, cleanroom contamination
Purity, in semiconductor manufacturing, is the fraction of a material that is the intended element, and it is quoted in nines: 99.9999999 percent, nine nines, usually written 9N…
physical vapor deposition, what is pvd, sputtering, magnetron sputtering, ipvd, ionized pvd, evaporation
Physical vapor deposition is how a fab lays down most of its metal. A solid source material is physically knocked or boiled into a vapor inside a vacuum chamber, and that vapor…
