摘要:
A method for removing polishing byproducts and a polishing device are provided. The method includes mounting a positive electrode on the center of a polishing platen and a negative electrode on an edge of the polishing platen, applying a voltage between the positive electrode and the negative electrode after a polishing process for metal is finished, and rotating the polishing platen and rinsing a polishing pad with deionized water or a chemical cleaning solution to remove polishing byproducts that are formed in the polishing process. The combination of the centrifugal force and the electromotive force increases the removal rate of the polishing byproducts.

This disclosure is directed to a chemical mechanical polisher and a polishing pad component thereof. The chemical mechanical polisher comprises a polishing platen having a flat surface, and the polishing platen comprises: an electromagnet disposed under the flat surface and configured to fix a polishing pad base on the flat surface; and a switch configured to control the power-on and power-off of the electromagnet. The polishing pad component comprises a polishing pad base, and the polishing pad base is formed of a ferromagnetic material. The chemical mechanical polisher of this disclosure and the polishing pad component thereof can make polishing pad replacement easy, and can also save polishing pads and thus reduce the consumable cost of the chemical mechanical polishing.

A stylus retaining mechanism for portable electronic device includes a main body, a latching portion, and an elastic member. The main body defines an opening and a receiving chamber communicating with the opening. The latching portion is positioned at one side of the receiving chamber spaced from the opening. The elastic member is fixed in the receiving chamber adjacent to the opening. The stylus is received in the receiving chamber. The elastic member prevents the stylus from separating from the main body when the stylus is disengaged from the latching portion.
摘要:
Technology for device discovery using a device-to-device (D2D) sounding reference signal (SRS) and device discovery using D2D SRS in a channel measurement group (CMG) is disclosed. In an example, a user equipment (UE) configured for device discovery via a node using the D2D SRS can include a transceiver module. The transceiver module can send a radio resource control (RRC) device discovery request to a node, scan D2D SRS subframes of proximity UEs using D2D SRS triggering, and send feedback to the node of detected D2D SRS information of the proximity UEs. The proximity UE can be located within a same cell as the UE.
