Definitions
- the invention relates to a substrate holder for holding substrates, in particular semiconductor wafers, with first and second parts, between which the substrate can be received.
- Such a substrate holder is described, for example, in German Patent Application No. 198 59 467, which did not prepublish and goes back to the same applicant.
- the substrate holder is particularly suitable for holding the semiconductor wafer during metal plating, in which a surface to be placed is exposed to an electrolyte, while the rest of the wafer is sealed to the electrolyte.
- a circumferential seal is provided on part of the substrate holder, which presses against the wafer when it is clamped in the substrate holder.
- the dimensions of the two parts of the substrate holder and the shape and position of the seal are selected so that a good seal is achieved with a certain wafer thickness.
- the sealing effect changes because a distance between the seal and a counter surface opposite the seal, between which the wafer is received, is essentially fixed.
- an incomplete sealing effect can lead to electrolyte reaching and damaging the areas of the wafer which are not to be plated during the plating of the wafer.
- the seal also has an undercut which enables electrical contact to be made with the surface of the wafer to be plated. It is achieved by a plurality of essentially radially extending contact springs with contact tips, which extend into the region of the undercut and are elastically prestressed against the wafer surface. By applying a voltage between that contacted by the contact springs The metal plating is promoted on the surface of the wafer and a counter electrode extending parallel to the wafer.
- the arrangement of the individual contact springs results in the problem that no homogeneous electric field is generated on the wafer surface, which results in an uneven metal deposition. For this reason, it is expedient to provide a ring electrode which radially surrounds the wafer and via which the electric field is homogenized. The radial distance between the electrode and the wafer should be kept as small as possible for a homogeneous field.
- the object of the invention is to create a substrate holder of the type mentioned at the outset which, regardless of the substrate thickness, enables a uniform reception, in particular a uniform clamping action, between the two substrate parts.
- the invention is also based on the object of reducing the radial dimension of the substrate holder in the region of the wafer.
- this object is achieved in the case of a substrate holder of the type mentioned at the outset in that the first part has a base body and at least one first support element which is movable relative thereto and which is elastically prestressed in the direction of the second part. This ensures that substrates with different thicknesses can be accommodated between the two parts of the substrate holder with essentially the same clamping effect.

- At least one guide element for guiding the base body and / or the first support element is to be used in the relative movement provided.

- At least one second support element which is movable relative to the base body and the first support element and is elastically prestressed in the direction of the second part.
- the second support element enables a substrate lying thereon to move relative to the base body and to the first support element in order to space it away and to facilitate access by a handling device.
- the second contact element can preferably be moved into a first position in which its contact surface lies above the contact surface of the first contact element.
- the second support element can preferably be moved into a position in which its support surface lies below the support surface of the first support element.
- the second support element is preferably guided in an opening of the first support element.
- a device for limiting the relative movement between the second support element and the base body and / or the first support element is preferably also provided in order to ensure uniform movement processes.
- the support surface of the second support element is preferably smaller than that of the first support element in order to provide the substrate by the first support element as uniformly as possible.
- At least one suction opening is provided in the support surface of the second support element.
- the second part of the substrate holder has a central opening adapted to the shape of the substrate in order to expose a region of the substrate surface facing the second part.
- a sealing element facing the substrate and surrounding the central opening is preferably provided on the second part in order to seal the exposed surface region from the remaining surface regions of the substrate.
- a locking unit is preferably provided for a secure hold of the two parts of the substrate holder to one another.
- the locking unit has a rotatable locking element on one part and a receptacle for receiving the locking element on the other part.
- the locking element is preferably biased into a locking position by means of at least one spring and can be moved with an actuating mechanism against the bias, so that the two parts are automatically locked when the actuating mechanism is released.
- an oblique locking surface is provided on the locking element and / or the receptacle in order to pull the two parts against one another during a relative movement between the locking element and the receptacle.
- the locking element has at least one holding part for holding and releasing the second support element.
- the second support element can preferably be moved against its bias by relative movement between the holding part and the second support element in order to control the movement of the second support element in a simple manner.
- At least one sealing element is preferably provided between the two parts of the substrate holder in order to seal the surface regions of the substrate enclosed between the substrate holders from the environment.
- the substrate holder preferably has at least one contact device for electrically contacting the surface of the substrate facing the second part in order to enable metal plating of the exposed substrate surface.
- the object of the invention is achieved in a substrate holder for holding substrates, in particular semiconductor wafers, with first and second parts between which the substrate can be received and at least one contact element for electrically contacting a surface of the substrate which has a connection end, a distance therefrom, overlapping the substrate Has contact end and a connecting part between the ends, solved in that the connecting part is guided by a guide substantially perpendicular to the contacting substrate surface on the outer circumference of the substrate, and the contact end is elastically biased towards the substrate surface.
- the radial dimensions of the substrate holder in the region of a substrate accommodated therein are kept small in order to enable the arrangement of a ring electrode radially surrounding the substrate.
- the connecting part is preferably movable parallel to the guide and the contact element is resilient at least in a region between the connection end and the guide in order to provide an elastic spring action away from the contact end.
- the contact element is preferably carried in a base body and forms a contact block with it, the guide preferably being part of the base body in order to provide a good and defined position of the contact element.
- a multiplicity of contact elements are preferably provided in a contact block in order to provide a multiplicity of contact points on the substrate and thus reliable electrical contacting of the substrate.
