Abstract: Some implementations described herein include systems and techniques for fabricating a wafer-on-wafer product using a filled lateral gap between beveled regions of wafers included in a stacked-wafer assembly and along a perimeter region of the stacked-wafer assembly. The systems and techniques include a deposition tool having an electrode with a protrusion that enhances an electromagnetic field along the perimeter region of the stacked-wafer assembly during a deposition operation performed by the deposition tool. Relative to an electromagnetic field generated by a deposition tool not including the electrode with the protrusion, the enhanced electromagnetic field improves the deposition operation so that a supporting fill material may be sufficiently deposited.

Abstract: The present disclosure, in some embodiments, relates to a method of forming an integrated chip structure. The method may be performed by forming a plurality of interconnect layers within a first interconnect structure disposed over an upper surface of a first semiconductor substrate. An edge trimming process is performed to remove parts of the first interconnect structure and the first semiconductor substrate along a perimeter of the first semiconductor substrate. The edge trimming process results in the first semiconductor substrate having a recessed surface coupled to the upper surface by way of an interior sidewall disposed directly over the first semiconductor substrate. A dielectric capping structure is formed onto a sidewall of the first interconnect structure after performing the edge trimming process.

Abstract: A stationary device with an encrypted file access function and access method thereof are provided. The portable electronic device sends an access request of an electronic confidential file to the stationary device through a proximal connection. The stationary device sends an access request to the cloud server through a remote connection. Then the cloud server gives the corresponding access commands and verification commands to the portable electronic device and the stationary device. After the stationary device verifies that the access command matches the verification command through the proximal connection, the portable electronic device is allowed to access the electronic confidential file. The portable electronic device and the stationary device constantly check whether they are still within a certain distance, so as to restrict the user from accessing the electronic confidential file only in specific areas. Thus, the business secrets and national defense secrets are effectively protected.

Abstract: A power supply circuit includes a power converter, an input voltage source, and a clamping circuit. The power converter has an input pin, an output pin, and an enable pin. The input voltage source is electrically connected to the input pin, and provides an input voltage to the input pin.

When the input voltage increases to at least a threshold input voltage, the clamping circuit is configured to activate the power converter to provide an output voltage at the output pin. When the input voltage decreases below the threshold input voltage, the clamping circuit is configured to deactivate the power converter and prevent the power converter from being re-activated within a predefined time period.

Abstract: A method includes forming a gate electrode on a semiconductor region, recessing the gate electrode to generate a recess, performing a first deposition process to form a first metallic layer on the gate electrode and in the recess, wherein the first deposition process is performed using a first precursor, and performing a second deposition process to form a second metallic layer on the first metallic layer using a second precursor different from the first precursor. The first metallic layer and the second metallic layer comprise a same metal. The method further incudes forming a dielectric hard mask over the second metallic layer, and forming a gate contact plug penetrating through the dielectric hard mask. The gate contact plug contacts a top surface of the second metallic layer.

Abstract: A barbecue grill includes a barrel and a supporting unit. The barrel includes multiple panels and two lugs. The panels are pivotally connected to one another so that the barrel is switchable between an extended position and a collapsed position. The lugs are formed on one of the panels.

The pivots extend from the lateral sections, respectively. The pivots are inserted in the lugs when the lateral sections are released. The pivots are disengaged from the lugs when the lateral sections are moved relative to each other. The loops are located on and connected to the lateral sections.

Abstract: A box cutter includes a blade, a handle, a sheath and a restraining element. The handle includes a space for receiving a rear portion of the blade, a chamber in communication with the space, a rear slot in communication with the space, and a front slot in communication with the chamber. The sheath is movable in the chamber and covers a front portion of the blade. The restraining element is movable in the handle between a locking position and an unlocking position. In the locking position, the restraining element abuts against the sheath to prevent the sheath from retreating into the handle to keep on covering the front portion of the blade. In the unlocking position, the restraining element is moved from the sheath to allow the sheath to retreat into the handle to allow the front portion of the blade to extend from the sheath.
