Abstract: A radiation source apparatus includes a vessel, a laser source, a collector, a horizontal obscuration bar, and a reflective mirror. The vessel has an exit aperture. The laser source is configured to emit a laser beam to excite a target material to form a plasma. The collector is disposed in the vessel and configured to collect a radiation emitted by the plasma and to reflect the collected radiation to the exit aperture of the vessel. The horizontal obscuration bar extends from a sidewall of the vessel at least to a position between the laser source and the exit aperture of the vessel. The reflective mirror is in the vessel and connected to the horizontal obscuration bar.

Abstract: An integrated circuit device includes a device layer having devices spaced in accordance with a predetermined device pitch, a first metal interconnection layer disposed above the device layer and coupled to the device layer, and a second metal interconnection layer disposed above the first metal interconnection layer and coupled to the first metal interconnection layer through a first via layer. The second metal interconnection layer has metal lines spaced in accordance with a predetermined metal line pitch, and a ratio of the predetermined metal line pitch to predetermined device pitch is less than 1.

Abstract: In an embodiment, a chemical mechanical planarization (CMP) system includes: a monolithic platen within a platen housing, wherein the monolithic platen is formed of a single piece of material, wherein the monolithic platen includes: a first portion within a first opening, and a second portion within a second opening, wherein the first portion has a different diameter than the second portion; and a polishing fluid delivery module above the monolithic platen, wherein the polishing fluid delivery module is configured to deliver slurry to the monolithic platen during performance of CMP.

Abstract: A 5G outdoor unit having a heat dissipation function includes a main body and a support frame. The main body includes a housing, a cover, and an antenna, the cover is mounted on one side of the housing, and the antenna is disposed on an inner side of the cover. The support frame includes a first side plate, a second side plate, and a plurality of heat dissipation fins. The first side plate is mounted on an outer side of the cover, the fins are arranged between the first side plate and the second side plate at intervals, and a channel is formed between the two adjacent heat dissipation fins. As such, the main body and the support frame are two separate elements. The volume of the main body is reduced, and the weight of the main body is less.

Abstract: An electronic device including a housing and a base frame is provided. A first plane of the housing has a groove including a first connecting part. A second plane of the housing has a second connecting part. The base frame includes a third connecting part and a fourth connecting part. In a first assembly mode, the third connecting part is connected to the first connecting part so that the base frame is fixed to the groove. In a second assembly mode, the fourth connecting part is connected to the second connecting part so that the base frame is fixed to the second plane of the housing and supports the housing with a third plane adjacent to the second plane.

Abstract: A method of generating a barcoded Paired-End Ditag (bPED) nucleic acid fragment is disclosed. The method comprises: a) performing a first ligation by ligating a half-adaptor with one or two 3?-overhanging ends to a target nucleic acid to obtain a nucleic acid fragment with two ends each attached to one of the half-adaptor, the half adaptor comprising a half-barcode and a restriction enzyme (RE) recognition site; b) performing a second ligation by ligating two of the half-adaptor at the two ends of the nucleic acid fragment to form a circularized nucleic acid construct, wherein the circularized nucleic acid construct comprises a full-size barcoded adaptor; and c) digesting the circularized nucleic acid construct with a RE that cleaves at a defined distance from the RE recognition site, and thereby generating the bPED nucleic acid fragment.

Abstract: An universal serial bus socket is disclosed, which comprises: a shell, disposed on a planar surface, being formed with a first surface and a second surface at positions corresponding to each other while having a slot to be formed thereon with a length extending in an extending direction forming a first included angle with respect to the planar surface; and an USB connector, being arranged inside the slot while allowing an USB jack of the USB connector to expose outside the first surface of the shell so as to be provided for an USB plug to plug in; wherein the first included angle is not equal to 90 degrees, and the USB plug is arranged to plug into the USB jack in a plug-in direction that forms a second included angle with respect to the planar surface while allowing the second included angle to be not equal to 90 degrees.
