Abstract: A semiconductor device a first fin-shaped pattern provided at a first surface of a substrate and extending in a second direction, a first source/drain pattern disposed on the first fin-shaped pattern and connected thereto, a first source/drain contact disposed on the first source/drain pattern and connected thereto, a buried conductive pattern extending through the substrate and connected to the first source/drain contact, a contact connection via disposed between the first source/drain contact and the buried conductive pattern. The contact connection via is directly connected to the first source/drain contact and a back wiring line disposed on a second surface of the substrate and connected to the buried conductive pattern. A width of the contact connection via increases as the contact connection via extends away from the second surface. A width of the first source/drain contact decreases as the first source/drain contact extends away from the second surface of the substrate.

Abstract: Disclosed are an ultrasound imaging system for analysis of a body composition and an operation method of an ultrasound imaging system which is designed for analysis of a body composition. An ultrasound imaging system may include: a scan device into which an object is insertable; an ultrasonic probe connected to a part of the scan device; a controller configured to control the ultrasonic probe to emit a transmission ultrasonic signal to the object at multiple positions at the scan device, and receive a reflection ultrasonic signal reflected from the object; and an image processor configured to generate multiple 2D ultrasound images based on reflection ultrasonic signals received at the multiple positions at the scan device, respectively, and generate a 3D ultrasound image based on the multiple 2D ultrasound images.

Abstract: According to the present disclosure, there is provided a cell stimulation and culture platform using a ultrasonic hologram, including a culture vessel in which a culture well with an open lower portion is formed; a transmission sheet which is installed to cover a lower surface of the culture vessel and where a biological sample is seated; a platform body that is filled with a liquid medium and an open upper end is covered by the transmission sheet; an ultrasonic transducer that is installed inside the platform body in a state of being spaced apart from the biological sample; and an ultrasonic hologram lens that is installed on the ultrasonic transducer, and spatially modulates the phase of the ultrasonic waves using a surface structure designed to have different height distributions to focus the ultrasonic waves in a set pattern shape on a target surface on which the biological sample is located.

Abstract: Disclosed are a bladder monitoring apparatus which accurately determines a bladder status of a subject based on an ultrasonic image and a posture of the subject and a method for controlling the bladder monitoring apparatus. The bladder monitoring apparatus includes a processor, a memory configured to operably connected to the processor and store at least one code executed by the processor, and a transceiver configured to receive a reflection ultrasonic signal from a subject and a posture sensing signal obtained by sensing a posture of the subject based on a sensor, and the memory may store a code which is executed by the processor to cause the processor to determine the bladder status of the subject by applying the machine learning-based learning model to an ultrasonic image generated from the reflection ultrasonic signal and posture information generated based on the posture sensing signal.
