Title: Vladimir Petrovsky: Innovator in Dielectric Measurement and Photoresist Technology

Introduction

Vladimir Petrovsky is a notable inventor based in Rolla, MO (US), recognized for his contributions to the fields of dielectric measurement and photoresist technology. He holds 2 patents that showcase his innovative approaches to solving complex problems in material science.

Latest Patents

One of Petrovsky's latest patents is a method for determining the dielectric constant of particles. This method involves selecting a powder with an unknown first dielectric constant and a liquid with a known second dielectric constant. By introducing a predetermined amount of powder into a predetermined volume of liquid, a slurry is created with a known volume fraction of powder. The impedance spectra of the slurry is then plotted over a predetermined frequency range, allowing for the calculation of the first dielectric constant using appropriate equivalent circuit equations.

Another significant patent is for a highly plasma etch-resistant photoresist composition containing a photosensitive polymeric titania precursor. This composition is derived from an addition polymerizable organotitanium polymer, which, upon exposure to oxygen plasma or baking in air, converts to titanium dioxide (titania) or a mixed titanium-containing metal oxide. The resulting metal oxide provides etch-resistant properties to a patterned photoresist layer, and the composition can also be directly deposited and patterned into permanent metal oxide device features through a photolithographic process.
