Abstract: A method of bonding a die to a wafer using a die bonding system measures, using an obtained image showing interference fringes, a parallelism between the die and the wafer. In some embodiments, parallelism and die deformation are detected using interference fringes produced by an optical apparatus of the die bonding system. A parallelism measurement optical apparatus includes a light source, an optical assembly configured to control polarization of a reference light and a measurement light. In some embodiments, the measurement light is sequentially incident on and reflected from a first measurement surface and a second measurement surface that are spaced apart along a vertical direction to face each other, and is emitted to have information on parallelism between the first and second measurement surfaces. In some embodiments, a first polarizer is configured to interfere the reference light and the measurement light emitted from the optical assembly with each other. A light detector is configured to detect an interference signal of lights including the interference fringes.

Abstract: An example semiconductor measurement apparatus includes a light source, a pattern generator, a stage, an image sensor, and a controller. The light source is configured to output light in a predetermined wavelength band. The pattern generator is configured to generate light including a speckle pattern by scattering the light output from the light source. The stage is disposed on a movement path of the light including the speckle pattern, and a sample reflecting the light including the speckle pattern is seated on the stage. The image sensor is configured to receive light reflected from the sample and generate an original image representing a diffractive pattern of light reflected from the sample. The controller is configured to generate a prediction image for estimating diffractive characteristics of light incident on the image sensor.

Abstract: In an apparatus, a memory controller, a memory device, and a method for switching frequencies of clock signals to reduce power consumption, when the memory device performs an internal operation according to a command of the memory controller, a frequency of a clock signal of the memory controller is changed. The memory controller switches the frequency of the clock signal to a low frequency according to assertion of a status signal that indicates a busy operation status of the memory device according to the command, and switches the frequency of the clock signal to a high frequency according to de-assertion of the status signal that indicates a ready operation status of the memory device.
