Latest Patents
Sekizawa's latest patents include innovative methods for creating titania-doped quartz glass and synthetic quartz glass ingots. The first patent describes a method for preparing titania-doped quartz glass suited for EUV lithographic applications. This process involves feeding silicon and titanium reactant gases through a burner, along with hydrogen and oxygen, to form synthetic silica-titania fine particles. These particles are then deposited on a rotating target, melted, and vitrified to grow an ingot of titania-doped quartz glass. The method ensures that the growth front of the ingot is maintained at a safe distance from the burner tip. His second patent focuses on the manufacture of synthetic quartz glass ingots through vapor phase hydrolysis or oxidative decomposition of silica feedstock. This method allows for the continuous feeding of silica, maintaining the flame's contact with the growing face, and cyclically moving the target to form a consistent synthetic quartz glass ingot.
