Abstract: Semiconductor devices and methods of fabricating the semiconductor devices are described herein. The method includes steps for patterning fins in a multilayer stack and forming an opening in a fin as an initial step in forming a multilayer source/drain region. The opening is formed into a parasitic channel region of the fin. Once the opening has been formed, a source/drain barrier material is deposited using a bottom-up deposition process at the bottom of the opening to a level below the multilayer stack. A multilayer source/drain region is formed over the source/drain barrier material. A stack of nanostructures is formed by removing sacrificial layers of the multilayer stack, the multilayer source/drain region being electrically coupled to the stack of nanostructures.

Abstract: An intraoral phototherapy device for simultaneously irradiating inner and outer gingiva includes a transparent shell and a circuit board. The transparent shell includes a bite portion and a stop portion. The bite portion is mounted on an inner arc surface of the stop portion. The circuit board is mounted in the bite portion, and includes first and second light emitting units. The first and the second light emitting units emit lights toward a first and a second surface of the bite portion. When a user bites the bite portion and turn on the intraoral phototherapy device, the lights emitted by the first and the second light emitting units are emitted to a gum inside and outside upper and lower jaw teeth of the user. Therefore, the intraoral phototherapy device can stimulate an affected part of a gingivitis through a photobiomodulation therapy to achieve an effect of anti-inflammation or alleviating pain.

Abstract: An optical water quality detection device with an examining property probe, which includes two stationary seats and a fencing frame. The fencing frame is detachably mounted in a detecting channel between the two stationary seats and has a guiding protrusion and two elongated orifices. The guiding protrusion protrudes from an inner side of an upper portion of the fencing frame and has a convex surface. The convex surface extends along a cycloidal path. The two elongated orifices are formed through the two side panels respectively and extend to the bottom panel. The cycloidal path on the convex surface in the fencing frame, with its structural design, assists in guiding the air bubbles stuck in the detecting channel to leave the detecting channel without vibrating the examining property probe. Since the air bubbles do not remain in the detecting channel, the spectral information is not affected.

Abstract: System and methods for geosteering inversion are provided. Downhole tool responses are predicted for different points along a planned path of a wellbore during a downhole operation, based on each of a plurality of inversion models. Measurements of the downhole tool's actual responses are obtained as the wellbore is drilled over the different points during a current stage of the operation. The inversion models are clustered based on a comparison between the actual and predicted tool responses and a randomly selected centroid for each cluster. The inversion models are re-clustered using an average inversion model determined for each cluster as the centroid for that cluster. At least one of the re-m clustered inversion models is used to perform inversion for one or more subsequent stages of the downhole operation along the planned wellbore path. The planned wellbore path is adjusted for the subsequent stage(s) of the downhole operation.

One of both horizontal sides of the optical waveguide lens is a tilted reflective surface while the other is a light-coupling surface aligned with the fibers.

Abstract: The package structure having packaged components within includes a circuit board, multiple packaged light detecting components mounted on the circuit board, a sealing cap being light transmittable, multiple light filtering films mounted on the sealing cap, and a supporting annular wall. The two opposite ends of the supporting annular wall are adhesively bonded to the surfaces of the circuit board and the sealing cap, such that the projection on the circuit board of the light filtering films corresponds the packaged light detecting components. Since the light filtering films have different filtering frequency bands, each packaged light detecting component detects light of different frequency bands in one incident light beam. The package method is simple and stable, effectively lowering the manufacture cost of the light detecting module.
