  • Patent number: 11341305
    Abstract: A method of predicting a shape of a semiconductor device includes implementing a modeled semiconductor shape with respect to a designed semiconductor layout, extracting a plurality of samples by independently linearly combining process variables with respect to the modeled semiconductor shape; generating virtual spectrums with respect to ones of the extracted plurality of samples through optical analysis, indexing the virtual spectrums to produce indexed virtual spectrums, generating a shape prediction model by using the indexed virtual spectrums as an input and the modeled semiconductor shape as an output, and indexing a spectrum measured from a manufactured semiconductor device and inputting the spectrum to the shape prediction model to predict a shape of the manufactured semiconductor device.

  • Patent number: 9261088
    Abstract: A linear compressor can prevent leakage of a magnetic force by changing the construction of a linear motor. As the construction of the linear motor is changed, a mechanical spring constant is set smaller in consideration of a magnetic spring constant, so that the size of springs supporting a piston in the reciprocal linear motion direction can be reduced and components supporting the springs can be removed. Therefore, the linear compressor achieves a small size/a light weight. With the characteristics of the linear motor construction, the linear compressor can suppress a stroke spreading influence and easily expand a compression capacity according to a load.
