  • Publication number: 20240094704
    Abstract: Determining a semiconductor device manufacturing parameter may include determining an EPM (electrical measurement parameters) group that has a correlation in a baseline EPM dataset including EPMs of a device manufactured under a baseline condition, deriving principal components (PCs) corresponding to main correlation axes between EPMs in the EPM group, deriving a PC-based dataset including a baseline PC dataset and a conditional split PC dataset by converting the baseline EPM dataset and a conditional split EPM dataset measured from devices manufactured under conditional splits into a PC domain, determining, using the PC-based dataset, respective PCs which are effectively changed by the conditional splits, obtaining split variation information of the conditional splits, extracting an optimal point capable of optimizing a figure of merit of a semiconductor device within a range of the PC-based dataset, and deriving information for process feedback for realizing the optimal point using the split variation infor

  • Publication number: 20230274985
    Abstract: Disclosed are a method and apparatus for setting a semiconductor parameter. The method for setting a semiconductor parameter according to an embodiment of the present disclosure is a method performed on a computing apparatus including one or more processors and a memory storing one or more programs executed by the one or more processors, the method including acquiring electrical measurement parameters corresponding to preset semiconductor manufacturing parameters, classifying the electrical measurement parameters into a plurality of groups according to a degree of correlation, extracting a correlation axis reflecting a correlation between electrical measurement parameters belonging to a corresponding group for each classified group, and predicting a figure of merit of a semiconductor device by using data values of electrical measurement parameters belonging to the corresponding group as input based on the correlation axis of each group.

  • Patent number: 11557652
    Abstract: Disclosed is a metal source/drain-based field effect transistor having a structure that replaces a portion of a semiconductor of a source/drain with a metal and a method of manufacturing the same. By replacing the source/drain region with the source/drain metal region, increase of the parasitic resistance of a conventional three-dimensional MOSFET of several tens of nanometers, lattice mismatch of the source/drain during selective epitaxial growth, and self-heating effect can be fundamentally solved. Further, since the metal is deposited after the partial etching of the source/drain region or the selective epitaxial growth is partially performed under the conventional CMOS process, the process can be performed without using any additional mask.

  • Patent number: 11387317
    Abstract: Disclosed is a field effect transistor including an insulating film disposed between a source/drain region and a substrate. Since the insulating film prevents current leakage under a channel, it is not necessary to form a punch-through stopper. Further disclosed is a method of forming a field effect transistor.
