Abstract: The present disclosure provides a method for fabricating an image sensor. The method includes the following operations. A cavity is formed at a first surface of a substrate. A germanium layer is formed in the cavity. A first heavily doped region is formed in the germanium layer by an implantation operation. A second heavily doped region is formed at a position proximal to a top surface of the germanium layer, wherein the second heavily doped region is laterally surrounded by the first heavily doped region from a top view perspective. An interconnect structure is formed over the germanium layer.

Abstract: The beamforming calibration system includes a transmitter, a receiver, and a computing device. The transmitter includes multiple transmitting antennas. The computing device provides multiple phase sets to the transmitter. When the computing device provides a first phase set among the phase sets to the transmitter: the transmitter uses the first phase set to set phases of the transmitting antennas, the receiver receives wireless transmission signal from the transmitting antennas to obtain a first radiation pattern corresponding to the first phase set, and the computing device is configured to compare the first radiation pattern with a predetermined pattern to calculate a pattern similarity score corresponding to the first phase set. The computing device selects a calibration phase set among the phase sets according to the pattern similarity score of each phase set, and provides the calibration phase set to the transmitter to calibrate beamforming.

Abstract: A multiple-hop multi-input multi-output (MIMO) amplify-and-forward relay wireless communication system includes a signal source node, a signal destination node and a plurality of relay nodes, wirelessly coupled between the signal source node and the signal destination node. The relay nodes feed back a plurality of signal to noise ratio information and a plurality of antenna number information to the signal source node. The signal source node allocates a plurality of corresponding transmission powers for the relay nodes and sends to the relay nodes.

Abstract: A two-way propelling type transmission mechanism for bicycle is disclosed having a control line operable to pull a bearing ring and a directional gear away from the series of clutch teeth of a first gear into engagement with the series of clutch teeth of a second gear so that pedaling the pedals to rotate cranks either forwardly or backwardly can drive the first gear to rotate a gear cluster in moving the bicycle forwards.

Abstract: A passivation structure for a semiconductor device includes a high ultraviolet transmittance silicon nitride (UV-SiN) layer. This UV-SiN layer substantially conformally overlies a plurality of top metal lines, which are formed over a semiconductor substrate, such that topographical hollows are defined between adjacent top metal lines. A spin-on glass (SOG) material fills in the topographical hollows. A silicon oxynitride (SiON) layer having a thickness in a range from about 8,000 angstroms to about 10,000 angstroms overlies the UV-SiN layer and the SOG material. A method for forming the passivation structure also is described.
