Abstract: An adjustable marker reference device for identifying surgical instruments includes a base, an upper cover, a set of connecting rods, markers and a fixing button. The base has a first groove, and the upper cover has a second groove. The set of connecting rods is disposed between the base and the upper cover, and has two movable ends and a pivot point. The fixing button extends through the first groove, the pivot point and the second groove. When the fixing button is pressed, the set of connecting rods can freely bring the pivot point to slide along the first groove and the second groove. When the fixing button is not pressed, the pivot point is fixed at one of default positions. As the set of connecting rods is fixed, virtual lines between any two of the markers meet specific conditions.

Abstract: A method of fabricating a semiconductor device is provided. In the method, a gate structure is formed on a semiconductor substrate. A photolithography process is performed with a mask having two transparent regions to form a photoresist layer having two openings in the semiconductor substrate. A first photoresist layer of the photoresist layer between the two openings is aligned to the gate structure and formed on the gate structure. The width of the first photoresist layer is shorter than the width of the gate structure such that a first side portion and a second side portion of the gate structure are exposed from both sides of the first photoresist layer, respectively. Next, an ion implantation process is performed to form lightly doped drain regions in the semiconductor substrate which are on two opposite sides of the gate structure of the photoresist layer.
