Abstract: A device a includes a substrate, two source/drain (S/D) features over the substrate, and semiconductor layers suspended over the substrate and connecting the two S/D features. The device further includes a dielectric layer disposed between two adjacent layers of the semiconductor layers and an air gap between the dielectric layer and one of the S/D features, where a ratio between a length of the air gap to a thickness of the first dielectric layer is in a range of 0.1 to 1.0.

Abstract: A manufacture defect analyzer (MDA) with a detecting function and inspecting method thereof are provided. The manufacture defect analyzer with a detecting function is for checking a to-be-inspected circuit board comprising a socket. The socket has an upper cover. The manufacture defect analyzer comprises a carrier, a detecting apparatus and an analyzer. The carrier is for supporting the to-be-inspected circuit board. The detecting apparatus corresponds to the socket and is disposed on the carrier and detects whether the upper cover is open. If the upper cover is open, then an open signal is outputted. After receiving the open signal, the analyzer is electrically connected to the socket to check whether the socket has any manufacture defect or not.

Abstract: Disclosed is a windshield wiper protector which lifts up the wiper from the surface of the front window when car is stopping or parking through collaborated action of a car engine initiation switch, a motor, a relay, and two stage gear speed reduction so as to keep the wiper away from contamination and prolong its lifetime.

Abstract: Disclosed herein is an innovated windshield wiper protector for an automobile. It comprises a pressurized fluid container, in which a plunger, a solenoid operated device, a pressurized fluid chamber, a spring, and a push bar with an adjustable screw are provided. By energizing or de-energizing the solenoid operated device, the plunger may reciprocate in the pressurized fluid container so as to vary the fluid pressure in the pressurized fluid chamber that causes the push bar to retract into or extend out of the chamber with the result that the wiper is made closely in contact with windshield glass, or the wiper is separated from the windshield glass with a clearance therebetween.
