  • Patent number: 10435807
    Abstract: Disclosed herein are lipseal assemblies for use in electroplating clamshells which may include an elastomeric lipseal for excluding plating solution from a peripheral region of a semiconductor substrate and one or more electrical contact elements. The contact elements may be structurally integrated with the elastomeric lipseal. The lipseal assemblies may include one or more flexible contact elements at least a portion of which may be conformally positioned on an upper surface of the elastomeric lipseal, and may be configured to flex and form a conformal contact surface that interfaces with the substrate. Some elastomeric lipseals disclosed herein may support, align, and seal a substrate in a clamshell, and may include a flexible elastomeric upper portion located above a flexible elastomeric support edge, the upper portion having a top surface and an inner side surface, the later configured to move inward and align the substrate upon compression of the top surface.
    Type: Grant

  • Patent number: 5360974
    Abstract: A dual quad flexure carriage and assembly, for receiving a sensing probe, is used for scanning the sensing probe across a target surface. The flexure carriage is a unitary structure providing flat motion for the sensing probe during the scanning procedure, while further compensating for thermal creep. The dual quad flexure assembly comprises the dual quad flexure carriage along with piezo actuators and control systems to provide highly linear orthogonal motion.

  • Patent number: 5262643
    Abstract: A non-contact, step-wise method for automatically positioning a sensing probe, having a vibrating cantilever and tip, above a target surface utilizing acoustic and Van der Waals interactions respectively during an approach method. The sensing probe is lowered to a substantially optimized tip to target surface distance. The system utilizes the interaction of forces between the vibrating cantilever and target surface to automatically position the sensing probe above the target surface.

  • Patent number: 5260577
    Abstract: A sample carriage, for receiving a sample to be scanned and positionable in a scanning probe microscope, is used for physically decoupling the sample from the scanning probe microscope assembly. The sample carriage, constructed from low thermal coefficient material, is physically decoupled by releasably clamping a sample carriage to a bridge support.
