Abstract: A matrix computing device and an operation method for the matrix computing device are provided. The matrix computing device includes a storage unit, a control circuit, and a computing circuit. The storage unit includes a weight matrix. The control circuit re-orders an arrangement order of weights in the weight matrix according to a shape of an output matrix to determine a weight readout order of the weights. The computing circuit receives the weights based on the weight readout order, and performs a matrix computation on the weights and an input matrix to generate a computing matrix. The control circuit performs a reshape transformation on the computing matrix to generate the output matrix, and writes the output matrix to the storage unit.

Abstract: A semiconductor image sensor includes a pixel. The pixel includes a first substrate; and a photodiode in the first substrate. The semiconductor image sensor further includes an interconnect structure electrically connected to the pixel. The semiconductor image sensor further includes a reflection structure between the interconnect and the photodiode, wherein the reflection structure is configured to reflect light passing through the photodiode back toward the photodiode.

Abstract: A method for manufacturing a semiconductor device includes forming a first dielectric layer over a semiconductor fin. The method includes forming a second dielectric layer over the first dielectric layer. The method includes exposing a portion of the first dielectric layer. The method includes oxidizing a surface of the second dielectric layer while limiting oxidation on the exposed portion of the first dielectric layer.

Abstract: An extraction device for extracting a beverage with cold or iced water has a tube, a fluid pressurization device and a connector. The connector has a holder with a bottom, a seat, an atomizer and a discharge pipe. The seat is mounted in the bottom of the holder and the atomizer is mounted through the holder and the seat. The extraction chamber is screwed into the seat and has a discharge orifice through which an extracted beverage passes. The fluid pressurization device is connected to the connector. The tube has an outlet end connected to the fluid pressurization device and inlet end connected to a water source. When the extraction device is used, a beverage can be extracted with cold water or iced water quickly, and the flavor of the extracted beverage can be maintained.
