    Abstract: The present disclosure relates to some embodiments of a method for improving processing efficiency of a cluster tool. The method comprises transferring a first lot of wafers from a transfer load lock to a designated storage load lock and transferring a second lot of wafers from the transfer load lock to the designated storage load lock while the first lot of wafers is in the transfer load lock or the designated storage load lock. The designated storage load lock has the same structure as the transfer load lock and respectively has an inner load lock portal at an interface with the first transfer chamber and an outer load lock portal on a sidewall of a front end interface. The inner load lock portal of the designated storage load lock is retained opened during processing. The outer load lock portal of the designated storage load lock is retained closed during processing.

    Abstract: Some embodiments relate to a cluster tool for semiconductor manufacturing. The cluster tool comprises a first transfer chamber having a first transfer robot. The cluster tool further comprises a designated storage chamber and a transfer load lock attached to the first transfer chamber. The cluster tool further comprises a second transfer chamber connected to the first transfer chamber through a pair of via connector chambers, the second transfer chamber having a second transfer robot. The cluster tool further comprises at least three epitaxial deposition chamber attached to the second transfer chamber. The cluster tool further comprises a control unit configured to control the second transfer robot to transfer wafers between the designated storage chamber and the transfer load lock.

    Abstract: The present disclosure relates to an improved method of forming interconnection layers to reduce voids and improve reliability, and an associated device. In some embodiments, a dielectric layer is formed over a semiconductor substrate having an opening arranged within the dielectric layer. A metal seed layer is formed on the surfaces of the opening using a chemical vapor deposition (CVD) process. Then a metal layer is plated onto the metal seed layer to fill the opening. Forming the metal seed layer using a CVD process provides the seed layer with a good uniformity, which allows for high aspect ratio openings in the dielectric layer to be filled without voids or pinch off.

    Abstract: In a method of manufacturing a semiconductor device, a thermal treatment is performed on a substrate, thereby forming a defect free layer in an upper layer of the substrate, where a remaining layer of the substrate is a bulk layer. A density of defects in the bulk layer is equal to or more than 1×108 cm−3, where the defects are bulk micro defects. An electronic device is formed over the defect free layer. An opening is formed in the defect free layer such that the opening does not reach the bulk layer. The opening is filled with a conductive material, thereby forming a via. The bulk layer is removed so that a bottom part of the via is exposed. A density of defects in the defect free layer is less than 100 cm−3.
