Abstract: A chamber for physical vapor deposition is provided. The chamber includes a housing, a door for opening and closing the housing, and a bearing for receiving a target, wherein the bearing is oriented in a first direction. Further, the chamber is adapted so that the target is at least partially removable from the chamber in the first direction. According to an embodiment, a chamber for physical vapor deposition is provided. The chamber is adapted for receiving at least one target and a substrate. The chamber includes a housing, a door, and at least one bearing for mounting the target, wherein the bearing is attached to the door.

Abstract: A rotatable target base device for sputtering installations is provided, wherein the target base device is adapted for receiving thereon a solid target cylinder, the rotatable target base device comprising a target base cylinder (4) having a lateral surface (3), a middle part (12), a first end region (7) and a second end region (9) opposite to the first end region, wherein at least one of the first and the second end regions has a maximum outer diameter substantially equal to or less than the outer diameter of the middle part.

Abstract: A rotatable target for a sputtering installation and a method for producing a rotatable target are provided. The target includes a backing tube to which a target tube is shrink-fitted. The method includes setting a positive temperature difference between a target tube and a backing tube. The method further includes pulling the target tube over the backing tube while the temperature difference remains positive. Furthermore, a backing tube having a middle part with an outer lateral area and a notch extending in a longitudinal direction on the outer lateral area is provided.

Abstract: An apparatus for electroplating one or more surfaces (2,3) on one or more substrates (1), especially solar cells (1a), is described. The apparatus includes an electrochemical coating bath (13), which has a coating tank (12) filled with an electrochemical coating liquid (14). The apparatus also includes a conveying device (15) for transporting the substrate through the coating bath (13), a light source circuit (60) with light sources (64) for irradiating the substrate (1) and an electrolytic cell rectifier circuit (50) for the substrate with anodes (54). The apparatus is characterized by a device for generating synchronous current pulses and light pulses, so that during a time interval between the current pulses the irradiating of the substrate or substrates is interrupted. A process for electrochemical plating of the surface of the substrate or substrates is also described.

Abstract: The electrolyte composition is used in a method of depositing metals, in particular, onto substrates, especially solar cells. The electrolyte composition is particularly suitable for the deposition of metals, in particular silver, onto solar cells. The electrolyte composition is preferably free of cyanides and contains at least one metal, preferably silver, and an iminodisuccinate derivative, preferably a sodium or postassium iminodisuccinate.
