摘要： A method for bonding a first substrate with a second substrate at respective contact faces of the substrates with the following steps: holding the first substrate to a first sample holder surface of a first sample holder with a holding force FH1 and holding the second substrate to a second sample holder surface of a second sample holder with a holding force FH2; contacting the contact faces at a bond initiation point and heating at least the second sample holder surface to a heating temperature TH; bonding of the first substrate with the second substrate along a bonding wave running from the bond initiation point to the side edges of the substrates, wherein the heating temperature TH is reduced at the second sample holder surface during the bonding.

摘要： A device and method is described for producing an electrically conductive direct bond between a bonding side of a first substrate and a bonding side of a second substrate. A workspace is included that can be closed, gas-tight, against the environment and can be supplied with a vacuum. The workspace includes a) at least one plasma chamber for modifying at least one of the bonding sides and at least one bonding chamber for bonding the bonding sides, and/or b) at least one combined bonding/plasma chamber for modifying at least one of the bonding sides and for bonding the bonding sides.

摘要： A method and corresponding device for bonding a first contact surface of a first substrate to a second contact surface of a second substrate. The method includes the steps of arranging a substrate stack, formed from the first substrate and the second substrate and aligned on the contact surfaces, between a first heating surface of a first heating system and a second heating surface of a second heating system.

摘要： A method for embossing a nanostructure, formed on a nanostructure punch, into a punch surface of a curable material which has been applied to a substrate. The method includes the following steps, especially following sequence: alignment of the nanostructure relative to the punch surface, embossing of the punch surface by a) prestressing of the nanostructure punch by deformation of the nanostructure punch and/or prestressing of the substrate by deformation of the substrate, b) making contact of a partial area of the punch surface with the nanostructure punch and c) automatic contacting of the remaining surface at least partially, especially predominantly, by the prestressing of the nanostructure punch and/or the prestressing of the substrate.

摘要： This invention relates to a method for bonding of a first contact surface of a first substrate to a second contact surface of a second substrate with the following steps, especially the following sequence: forming a reservoir in a surface layer on the first contact surface, the first surface layer consisting at least largely of a native oxide material, at least partial filling of the reservoir with a first educt or a first group of educts, the first contact surface making contact with the second contact surface for formation of a prebond connection, forming a permanent bond between the first and second contact surface, at least partially strengthened by the reaction of the first educt with a second educt contained in a reaction layer of the second substrate.
