A method of cooling a rack of heat dissipating components comprises cooling air, and porting the cooled air into a volume in front of the rack from above the volume. The method further comprises moving the cooled air from the volume in front of the rack to a plenum at a rear portion of the rack to pressurize the plenum. The cooled air is moved with an air mover disposed at a bottom portion of the rack, The method also comprises flowing air from the pressurized plenum past or through heat dissipating components in the rack to the volume in front of the rack, by force of pressure in the plenum through air-directing ports in the plenum. The air may be flowed through the heat dissipating components, around the heat dissipating components, or both. The method further comprises drawing warm air from an upper portion of the volume in front of the racks to cool it again.

System for cooling components arranged within an enclosure

A method of growing a ribbon crystal provides a crucible containing molten material and passes string through the molten material to grow the ribbon crystal. The method further directs gas flow around the ribbon crystal such that the gas flows down along the ribbon crystal toward the crucible.

Controlling transport of gas borne contaminants across a ribbon surface

A ribbon crystal pulling furnace has an interior for enclosing at least a portion of one or more ribbon crystals, and an afterheater positioned within the interior. The afterheater has at least one wall with one or more openings that facilitate control of the temperature profile within the furnace.

Ribbon crystal pulling furnace afterheater with at least one opening

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.

Ribbon crystal string for increasing wafer yield

A ribbon crystal has a body and end string within the body. At least one end string has a generally concave cross-sectional shape and is formed from at least two individual strings.

Ribbon crystal end string with multiple individual strings

A ribbon crystal pulling furnace has a base insulation and a liner insulation removably connected to the base insulation. At least a portion of the liner insulation forms an interior for containing a crucible.

Removable thermal control for ribbon crystal pulling furnaces

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.

Ribbon crystal having reduced wetting string

A method of growing ribbon crystal provides a crucible containing molten material, and passes at least two strings through the molten material to produce a partially formed ribbon crystal. The method then directs a fluid to a given portion of the partially formed ribbon crystal to convectively cool the given portion.
