  • Patent number: 11721584
    Abstract: A wafer is processed by irradiating a region to be divided with a pulse laser beam with a wavelength having absorbability to generate a thermal stress wave and propagate the wave to the inside of the region to be divided. A crushed layer is formed by executing irradiation, with a pulse laser beam with a wavelength having transmissibility with respect to the wafer, matching with a time when the thermal stress wave is generated and reaching a depth position at which a point of origin of dividing is to be generated at a sonic speed according to the material of the wafer. Absorption of the pulse laser beam with the wavelength having the transmissibility in a region in which the band gap is narrowed due to a tensile stress of the thermal stress wave forms a crushed layer that serves as the point of origin of dividing.

  • Patent number: 11694423
    Abstract: A gated truncated readout system for position sensitive or imaging detectors that improves resolution over traditional readout systems. The readout system includes two or more amplifiers that receive a multichannel output analog data from the detector. Analog gates control circuitry, included in the readout circuit, receives the signals from the amplifiers, determines a fractional value of the sum-integral of the signals, and enables analog gates operation around an area of interest, disabling all other channels where noise dominates the signal value and thereby improving interpolation accuracy of the signals centroid position and the detector resolution. Filtered signals are transmitted to a centroid interpolation signal processing device for computation of the centroid position. As a result disabling all channels where noise dominates the signal value, the gated truncated readout system provides better accuracy improved detector resolution.
