Latest Patents

Yokoyama's latest patents focus on the apparatus for vaporization sequence for multiple liquid precursors used in semiconductor thin film applications. The first patent describes a process and apparatus for the processing of thin films on semiconductor substrates using one or more liquid precursor sources. In this method, the liquid precursor source with the highest vapor pressure is vaporized first and introduced as vapor into a common manifold connected to a processing chamber. The introduction point is spaced away from the processing chamber. Subsequently, a second liquid precursor source, with a lower vapor pressure, is introduced in vaporized form into the manifold at a point closer to the processing chamber. This sequence continues for each liquid precursor source, maintaining a temperature gradient along the manifold to mitigate premature boiling or condensation.
