Exempel på hur man kan använda PHOTOLITHOGRAPHIC i en mening

• It is a multiple-step photolithographic and physico-chemical process (with steps such as thermal oxidation, thin-film deposition, ion-implantation, etching) during which electronic circuits are gradually created on a wafer, typically made of pure single-crystal semiconducting material.
• It undergoes many microfabrication processes, such as doping, ion implantation, etching, thin-film deposition of various materials, and photolithographic patterning.
• Further, the high costs of photolithographic masks and other manufacturing prerequisites make it essential to design the circuit to be as close to perfect as possible before the integrated circuit is first built.
• Concentrated HF (typically 49% HF in water) etches silicon dioxide too quickly for good process control and also peels photoresist used in photolithographic patterning.
• Desbarats and Leggo were responsible for a number of pioneering printing, including the photoelectrotyping process Leggotype, the first halftone photography reproduction in commercial printing, and photolithographic techniques at a time when the technology was still rare.
• Contrasted with traditional applications, microplasma sputtering offers numerous advantages, including limited to no post-processing requirements, as controlled positioning of the substrate can produce precise patterning without the need for subsequent photolithographic masking and etching, and versatility of substrate form, in that microsputterers are not constrained to planar deposition.
• 75 mm thick and polished to obtain a regular, flat substrate, onto which microelectronic devices are built through various microfabrication processes, such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning.
• He greatly cheapened the production of colour work by a simplified form of this discovery: a photolithographic transfer from a negative of the original to stone, printed as a "key" in a suitable colour, superimposing thereon, in exact register, transparent tints in harmony with the original.
