Evergreen Solar, Inc. - Marlborough MA

International Classification:

C23D 5/00

US Classification:

428367, 428408, 428702, 428698

Abstract:

A string for use in a string ribbon crystal has a base portion with a refractory material, and an externally exposed layer radially outward of the refractory material. The base portion has a coefficient of thermal expansion that is generally matched with the coefficient of thermal expansion for silicon. The externally exposed layer has a contact angle with silicon of between about 15 and 120 degrees.

US Classification:

428373, 4273722, 4273977, 428391, 428367

Abstract:

A method of making string for string ribbon crystal provides a substrate having an outer surface, and extrudes refractory material over the substrate. The refractory material substantially covers the outer surface of the substrate. The method then cures the refractory material.

US Classification:

428192, 4274197, 4272493, 117 24

Abstract:

A method of forming a string for use in a string ribbon crystal provides a refractory metal as a core for the string and forms a first layer of material on the core. A method of growing a ribbon crystal provides a pair of strings. Each string has a refractory metal core. The method further passes the strings through a molten material to grow the ribbon crystal between the pair of strings.A ribbon crystal wafer includes a ribbon crystal material and a pair of strings in the ribbon crystal material. Each string defines an outer edge of the wafer, and each string includes a refractory metal core.

US Classification:

117 24, 65 90

Abstract:

A ribbon crystal has a body with a width dimension, and string embedded within the body. The string has a generally elongated cross-sectional shape. This cross-section (of the string) has a generally longitudinal axis that diverges with the width dimension of the ribbon crystal body.
