  • Patent number: 10802264
    Abstract: The present invention relates in general to microscopy systems. In particular, the present invention relates to microscopes rendering digital images of samples, with the capability to digitally control the focus of the microscope system, and the software used to control the operation of the digital microscope system. Further, the present invention relates to a microscope structure that allows for compact and multi-functional use of a microscope, providing for light shielding and control with samples that require specific light wavelength characteristics, such as fluorescence, for detection and imaging.
    Type: Grant

  • Patent number: 10163845
    Abstract: Disclosed is a method of measuring a free air ball size during a wire bonding process of a wire bonder, which comprises a position sensor and a bonding tool for forming an electrical connection between a semiconductor device and a substrate using a bonding wire. Specifically, the method comprises the steps of: forming a free air ball from a wire tail of the bonding wire; using the position sensor to determine a positional difference between a first and a second position of the bonding tool with respect to a reference position, wherein the first position of the bonding tool is a position of the bonding tool with respect to the reference position when the free air ball contacts a conductive surface; and measuring the free air ball size based on the positional difference of the bonding tool as determined by the position sensor. A wire bonder configured to perform such a method is also disclosed.
