Title: Melvyn E Cowher: Innovator in Magnetic Oxide Film Technology

Introduction

Melvyn E Cowher is a notable inventor based in Sturbridge, MA (US). He has made significant contributions to the field of chemical vapor deposition (CVD) processes, particularly in the deposition of magnetic oxides.

Latest Patents

Cowher holds a patent for "CVD Growth of magnetic oxide films having growth induced anisotropy." This innovative process allows for the deposition of magnetic oxides, such as garnets, with sufficient growth induced anisotropy to support stable bubble domains, even in very thin films. The method utilizes organometallic source compounds and operates at low growth temperatures below 900°C, with high nozzle velocities ranging from 200-600 cm/sec at room temperature. The oxidant gas mixture used contains about 30-50 mol percent O₂, deviating from the typical use of nearly 100 mol percent O₂ in conventional CVD processes. The gas flow is directed transversely to the substrate, optimizing the deposition process.
