Abstract: A method for CMP includes following operations. A metal stack is received. The metal layer stack includes at least a first metal layer and a second metal layer, and a top surface of the first metal layer and a top surface of the second metal layer are exposed. A protecting layer is formed over the second metal layer. A portion of the first metal layer is etched. The protecting layer protects the second metal layer during the etching of the portion of the first metal layer. A top surface of the etched first metal layer is lower than a top surface of the protecting layer. The protecting layer is removed from the second metal layer.

Abstract: The present disclosure provides a semiconductor structure with having a source/drain feature with a central cavity, and a source/drain contact feature formed in central cavity of the source/drain region, wherein the source/drain contact feature is nearly wrapped around by the source/drain region. The source/drain contact feature may extend to a lower most of a plurality semiconductor layers.

Abstract: Disclosed is an image registration and an augmented reality system and an augmented reality method thereof which is suitable for solving the problem of spatial localization of the temporomandibular joint (TMJ) in arthroscopic surgery. The system comprises a three-dimensional scanning model building device, a stereoscopic image photographing device, a projection device and an arithmetic unit. The three-dimensional scanning model was constructed by preoperative or intraoperative imaging of the patient, and the surface three-dimensional model constructed by the stereoscopic image photographing device was spatially aligned to remove the surface (skin layer) of the three-dimensional image to display the TMJ image. Through the calibration of the stereoscopic image photographing device and the projection device, accurate, three-dimensional TMJ image location information is projected onto the patient's body to achieve the purpose.

Abstract: An electrical probe includes a base body and a probe head. The base body has a main body portion and at least one positioning portion, and the positioning portion protrudes from the main body portion. The probe head is detachably disposed on the main body portion of the base body. The probe head has an outer edge away from a side of a central axis of the main body portion, and the positioning portion protrudes from the outer edge.

Abstract: A testing apparatus includes a thermal control chamber including a test room, which temperature is controlled within a testing temperature range; a carrier frame including a direction guiding unit installed securely within the test room and formed with one guiding groove and a carrier rod extending through the guiding groove in the direction guiding unit; and a clamping unit mounted on the carrier rod for clamping a display-panel module securely, wherein, movement of the carrier rod transversely within the guiding groove relative to the direction guiding unit results in disposing the display-panel module to extend along one of several testing directions for undergoing a burn-in test.

Abstract: A method of manufacturing a charging capacity structure includes steps of: forming a first oxide layer, a support layer and a second oxide layer on a substrate in sequence; forming a plurality of etching holes on the surface of the second oxide layer in a matrix to run through the substrate that are spaced from each other at a selected distance; forming a plurality of pillar layers in the etching holes; removing the second oxide layer by etching; forming an etching protection layer on the surfaces of the support layer and pillar tubes that is formed at a thickness one half of the spaced distance between the etching holes such that the pillar tubes at diagonal locations form a self-calibration hole; and finally removing the first oxide layer from the self-calibration hole by etching. Through the self-calibration hole, the invention needn't to provide extra photoresists to form holes.
