摘要:
A deposition apparatus includes an input spool located in non-vacuum input module, at least one vacuum process module, an accumulator, and an air to vacuum sealing mechanism. The accumulator and the sealing mechanism are configured to continuously provide a web substrate from the input spool at atmosphere into the at least one process module at vacuum without stopping the web substrate.

A sputtering target assembly, including a cylindrical backing tube, a magnet assembly disposed within the backing tube, and a conduit disposed within the backing tube and adapted for transporting coolant. The conduit includes at least one first opening positioned for providing the coolant in a substantially circumferential direction from the conduit toward an inner surface of the backing tube into a gap volume between a front side of the magnet assembly and the inner surface of the backing tube.

Disclosed are apparatuses and methods for cutting thin film solar cells. The apparatus may include circular knife cutter rollers, each having a knife edge and coupled with a cutter arbor, support rollers, each coupled to a support arbor and having first and second outer surfaces and a circumferential gap between the first and second outer surfaces partially defined by a first side, a second side facing and offset from the first side, a first rounded edge where the first side intersects with the first outer surface, and a second sharp edge where the second side intersects with the second outer surface. The cutter arbor and support arbor are offset, and the knife cutter rollers and support rollers are axially spaced, such that one knife edge is positioned in the gap of each support roller and the web may be fed between the cutter arbor and the support arbor.

A sputtering target has a cylindrical backing tube having two edges and a sidewall comprising a middle portion located between two end portions. The sputtering material is on the backing tube. The sputtering material does not cover at least one end portion of the backing tube. The sputtering target also has a feature which prevents or reduces at least one of chalcogen buildup and arcing at the at least one end portion of the backing tube not covered by the sputtering material.

摘要:
A method for fabricating a solar cell. The method includes providing a thin metallic substrate in roll form. The method also includes applying an abrasive grit to a surface of the thin metallic substrate. The method includes mechanical-polishing the surface with the abrasive grit such that the surface is polished to remove at least one defect from the surface. Mechanical-polishing the surface of the thin metallic substrate is by a roll-to-roll polishing process of the surface of the thin metallic substrate. Moreover, the method includes depositing an absorber layer of the solar cell on the thin metallic substrate.

A shielding system for a physical vapor deposition chamber having a sputter target above the pedestal. The shielding system comprises a pedestal shield attachable to the pedestal and movable therewith. The pedestal shield surrounds and extends outward from the pedestal toward the chamber side or lower walls. The system also comprises a sidewall shield adapted to extend substantially around and within the chamber sidewalls, and downward from an upper portion thereof. The sidewall shield has a lower end extending inward and disposed adjacent the pedestal shield upper portion when the pedestal is in the raised position. The pedestal shield and sidewall shield cooperate, when the pedestal is in the raised position, to prevent line-of-sight deposition transmission from the sputter target to the side and lower walls of the deposition chamber.
摘要:
A method for a robotic semiconductor wafer processing system to correct for wafers that have become offset or off-center during wafer processing. This is accomplished by determining the amount of offset and re-centering the wafer during wafer transport to the next process station using a single station sensor to locate the wafer center point. Each single sensor located at each station activates when the wafer's edge traverses through the sensor's path. Directional coordinates for the measured designated points on the wafer's edge are calculated, and the intersection points of two circles, analytically derived from using the measured designated points as their centers, are determined. The intersection point closest to the true wafer center position represents the measured wafer's center point. This point is compared to the true wafer center position, and the wafer is then adjusted for this difference.

A land grid array socket and a microelectronic assembly including the socket. The socket comprises: a housing; an array of through-contacts on the housing; a solder ball standoff element on a PCB side of the housing; and a seating plane standoff element on a package side of the housing, the seating plane standoff element being aligned with the solder ball standoff element to form a loading force support element therewith.
