Title: Dana L Winchester: Innovator in Crystal Growth Technology

Introduction

Dana L Winchester is a prominent inventor based in Groton, MA (US). She has made significant contributions to the field of crystal growth technology, holding 2 patents that showcase her innovative approach to engineering.

Latest Patents

One of her latest patents is the "Wet-tip die for EFG crystal growth apparatus." This invention introduces a novel capillary die and crystal growing method designed for producing hollow crystalline bodies through the EFG process. The die features inner and outer annular moats that surround the die tip. These moats are equipped with passageways that supply melt from a crucible, ensuring that the melt wets and covers the die tip's surfaces during the growth process. The design allows for a lower die tip and shorter capillary compared to previous EFG dies, which enhances the uniformity of the crystalline body’s wall thickness. Additionally, the moats help prevent interruptions in the growth process by capturing liquid silicon in the event of a growth meniscus break, thereby reducing the risk of flooding.
