Abstract: A method of manufacturing a semiconductor device includes forming a gate electrode structure over a channel region, wherein the gate electrode structure includes a gate dielectric layer disposed over the first channel region, a gate electrode disposed over the gate dielectric layer, and insulating spacers disposed over opposing sidewalls of the gate electrode, wherein the gate dielectric layer is disposed over opposing sidewalls of the gate electrode. An interlayer dielectric layer is formed over opposing sidewalls of the insulating spacers. The insulating spacers are removed from an upper portion of the opposing sidewalls of the gate electrode to form trenches between the opposing sidewalls of the upper portion of the gate electrode and the interlayer dielectric layer, and the trenches are filled with an insulating material.

Abstract: A semiconductor device according to the present disclosure includes a first gate structure and a second gate structure aligned along a direction, a first metal layer disposed over the first gate structure, a second metal layer disposed over the second gate structure, and a gate isolation structure extending between the first gate structure and the second gate structure as well as between the first metal layer and the second metal layer.

Abstract: A device for adjusting the degree of tightness is provided. The device is for a first strap element and a second strap element. The device includes an outer adjustment element, an inner adjustment element, and an intermediate adjustment element. The inner adjustment element is disposed inside the outer adjustment element. The intermediate adjustment element is disposed between the inner adjustment element and the outer adjustment element. The first strap element includes a first hollow region, and the second strap element includes a second hollow region. The inner adjustment element passes through the first hollow region and the second hollow region to adjust the degree of overlapping of the first hollow region and the second hollow region.

Abstract: A head-mounted display includes a display device, a connecting structure and a head abutting portion. The connecting structure is in a shape of strip. The connecting structure has two opposite ends. The ends are respectively connected with the display device. The connecting structure and the display device define an accommodation space. The accommodation space is configured to accommodate a head of a user. The head abutting portion is pivotally connected with the connecting structure. The head abutting portion is at least partially located between the connecting structure and the display device. The head abutting portion is configured to abut against the head of the user.

Abstract: A head-mounted display includes a face-abutting frame, a first adjustable structure, a second adjustable structure and a display module. The face-abutting frame has a first side and a second side opposite to each other. The first side abuts against a face of a user. The face-abutting frame defines a space corresponding to eyes of the user. The first adjustable structure connects with the second side. The second adjustable structure connects with the second side and defines the space with the first adjustable structure. The second adjustable structure movably and mechanically connects with the first adjustable structure. The display module corresponds to the space and movably and mechanically connects with the first adjustable structure. The first and the second adjustable structures can move close to or away from each other. The display module and the first adjustable structure can move close to or away from each other.
