Ikoreshwa ryimyuka yumubiri (Physique Vapor Deposition, PVD) bivuga gukoresha uburyo bwumubiri mugihe cyimiterere ya vacuum kugirango ihindurwe hejuru yisoko yibintu (bikomeye cyangwa amazi) muri atome ya gaze cyangwa molekile, cyangwa igice cya ionize muri ion, kandi ikanyura muri gaze yumuvuduko ukabije (cyangwa plasma). Inzira, tekinoroji yo kubitsa firime yoroheje ifite umurimo wihariye hejuru yubutaka bwa substrate, hamwe no guhumeka imyuka yumubiri nimwe muburyo bukuru bwo kuvura hejuru. Ubuhanga bwo gutwika PVD (physique de vapor physique) bugabanijwemo cyane cyane mu byiciro bitatu: icyuka cyuka cya vacuum, icyuho cya vacuum hamwe na vacuum ion.
Ibicuruzwa byacu bikoreshwa cyane cyane mu guhumeka ubushyuhe no gutwikira. Ibicuruzwa bikoreshwa mu kubika imyuka birimo insinga ya tungsten, ubwato bwa tungsten, ubwato bwa molybdenum, hamwe n’ubwato bwa tantalum ibicuruzwa bikoreshwa mu gutwikira ibyuma bya elegitoronike ni insinga ya cathode tungsten, umuringa w’umuringa, tungsten uhambaye, hamwe n’ibice bitunganya molybdenum Intego za titanium, intego za chromium.
