Abstract: Disclosed herein are a neural network model deployment method and apparatus for providing a deep learning service. The neural network model deployment method may include providing a specification wizard to a user, searching for and training a neural network based on a user requirement specification that is input through the specification wizard, generating a neural network template code based on the user requirement specification and the trained neural network, converting the trained neural network into a deployment neural network that is usable in a target device based on the user requirement specification, and deploying the deployment neural network to the target device.

Abstract: There is provided a small and light ozone generating apparatus capable of producing ozone with much less consumption of electric power. The present invention comprises a pulse generator for generating high-voltage pulses and a discharge chamber for inducing electrical discharge in response to the high-voltage pulses. The pulse generator includes an LC circuit for compressing square wave signals and generating impulses. The use of impulse greatly reduces electric power consumption and volume of ozone generating apparatus. Electrical discharge takes place between an electrode plate and grounded chamber wall. A sheet of oxide dielectric covers the chamber wall to prevent corrosion of chamber wall.

Abstract: A compression molding method reduces or removes adhesion property between a mold substrate and a high polymer material, which is to be imprinted with a pattern from the mold substrate. Accordingly, a pattern having increased granularity to tens of A can be obtained for application to fabrication processes of semiconductor devices and electronic products. The compression molding method can use a patterned mold and preferably a high polymer material to be imprinted with the pattern. The method can further include heating one of the mold and the high polymer material, compression-molding the mold and the high polymer material, cooling the heated one for a prescribed time and separating the high polymer material and the mold from each other.

Abstract: A method of fabricating a semiconductor device having a substrate includes the steps of simultaneously forming an A copolymer having a columnar shape, a B copolymer surrounding the A copolymer, and a C copolymer surrounding the B copolymer on the substrate, removing the A copolymer to form a first hole on the substrate, forming the semiconductor device in the first hole; removing the B copolymer to form a second hole, forming an electrode on the semiconductor device for controlling an electric potential, and removing the C copolymer from the substrate.
