Abstract: A method for preparing a gate oxide layer is described. First, a trench surrounding an active area is formed in a substrate, and a dielectric block is then formed in the trench such that an upper surface of the dielectric block is not aligned with that of the substrate. Subsequently, an ion implantation process is performed to implant nitrogen-containing dopants into the substrate in the active area, and a thermal oxidation process is then performed to form a gate oxide layer on the surface of the substrate in the active area. Particularly, the concentration of the nitrogen-containing dopants at the center of the active area is higher than that at the edge of the active area. The nitrogen-containing dopants inhibit the reaction rate of the thermal oxidation process, so as to prevent the gate oxide layer from thinning at the edge near the trench.

Abstract translation: 描述了制备栅氧化层的方法。 首先，在基板中形成围绕有源区的沟槽，然后在沟槽中形成介质块，使得介质块的上表面与衬底的上表面不一致。 随后，进行离子注入工艺以将含氮掺杂剂注入到有源区域中的衬底中，然后执行热氧化工艺以在有源区域中在衬底的表面上形成栅极氧化层。 特别地，有源区中心的含氮掺杂剂的浓度高于有源区的边缘处的浓度。 含氮掺杂剂抑制热氧化过程的反应速率，以防止栅极氧化层在沟槽附近的边缘变薄。

Abstract: A universal entertainment system includes an entertainment unit, a universal mounting stand, and a folding joint. The entertainment unit includes an entertainment housing having a multimedia compartment, a display screen provided on a screen side, and a multi-functional multimedia circuitry disposed in the multimedia compartment for reading digital data of a multimedia. The universal mounting stand is adapted for supporting at a fixture surface. The folding joint pivotally connects the entertainment unit with the universal mounting stand in a rotatably movable manner, wherein the entertainment unit is adapted to pivotally fold with respect to the universal mounting stand to selectively adjust a tilt angle of the display screen with respect to the fixture surface and is adapted to rotatably fold with respect to the universal mounting stand to selectively adjust a revolving angle with respect to the universal mounting stand.
