![]() Finally, some of the models that have been developed to gain understanding of the discharge processes are reviewed, including the phenomenological material pathway model, and the ionization region model. Such a process has important applications in the filling of highaspectratio features encountered in microelectronics fabrication. HIPIMS utilises extremely high power densities of the order of kWcm 2 in short pulses (impulses) of tens of. Experimentally, ion flux fractions of greater than 80 can be obtained by sputtering aluminum into a region of dense plasma (ne1012 cm3). High-power impulse magnetron sputtering (HIPIMS or HiPIMS, also known as high-power pulsed magnetron sputtering, HPPMS) is a method for physical vapor deposition of thin films which is based on magnetron sputter deposition. Then the development and properties of the high power pulsed power supply are discussed, followed by an overview of the measured plasma parameters in the HiPIMS discharge, the electron energy and density, the ion energy, ion flux and plasma composition, and a discussion on the deposition rate. A simple model for ionization of sputtered metals by a highdensity plasma is presented. First, an introduction to the magnetron sputtering discharge and its various configurations and modifications is given. The technique economically creates a unidirectional. IEEE Transactions on plasma science 27 (5), 1516-1524, 1999. One promising new method of fabricating high-aspect ratio vias is ionized physical vapor deposition (I-PVD). 171: 1998: Miniaturization of inductively coupled plasma sources. The authors give an overview of the development of the HiPIMS discharge, and the underlying mechanisms that dictate the discharge properties. Ionized physical vapor deposition of integrated circuit interconnects. The HiPIMS discharge is now an established ionized physical vapor deposition technique, which is easily scalable and has been successfully introduced into various industrial applications. Abstract Ionized physical vapor deposition (IPVD) is a new method for depositingmetal into high-aspect-ratio features used as interconnects in microelectronic fabrication. IPVDSecondary discharge in a magnetron sputtering dischargeIn these discharges n Ar n M and the particle.This is a significant advantage over conventional dc magnetron sputtering where the sputtered vapor consists mainly of neutral species. This results in a high plasma density, and high ionization fraction of the sputtered vapor, which allows better control of the film growth by controlling the energy and direction of the deposition species. In HiPIMS, high power is applied to the magnetron target in unipolar pulses at low duty cycle and low repetition frequency while keeping the average power about 2 orders of magnitude lower than the peak power. ![]() The high power impulse magnetron sputtering (HiPIMS) discharge is a recent addition to plasma based sputtering technology.
