    Abstract: The method for manufacturing the heterojunction circuit according to one embodiment of the present disclosure comprises depositing a first electrode on at least a part of a waveguide, moving a semiconductor comprising a second electrode at a lower end thereof onto the first electrode, and depositing a third electrode on an upper end of the semiconductor, wherein the waveguide and the semiconductor comprise different materials. Additionally, the moving step further comprises generating microbubbles by supplying heat to at least a part of the semiconductor, moving the semiconductor on the first electrode by moving the generated microbubbles, and removing the microbubbles by positioning the semiconductor on the first electrode.

    Abstract: An electronic device and an operating method thereof may be configured to detect input data having a first time interval, detect first prediction data having a second time interval based on the input data using a preset recursive network, and detect second prediction data having a third time interval based on the input data and the first prediction data using the recursive network. The recursive network may include an encoder configured to detect each of a plurality of feature vectors based on at least one of the input data or the first prediction data, an attention module configured to calculate each of pieces of importance of the feature vectors by calculating the importance of each feature vector, and a decoder configured to output at least one of the first prediction data or the second prediction data using the feature vectors based on the pieces of importance.

    Abstract: An analog-digital converter includes a first analog-digital conversion unit configured to, during a first analog-digital conversion operation, sequentially charge each of n first differential node pairs, in response to a respective one of a differential sampling signal pair and first to (n−1)th differential signal pairs among n differential signal pairs, in response to each of the n first differential node pairs being sequentially charged, sequentially generate each of n first differential data pairs, and sequentially generate each of n upper differential data pairs to be used as n-bit upper digital data, in response to a respective one of the sequentially-generated n first differential data pairs. The first analog-digital conversion unit is further configured to, during a second analog-digital conversion operation, simultaneously discharge each of the n first differential node pairs, in response to a nth differential signal pair among the n differential signal pairs.
