Abstract: An integrated circuit device includes a semiconductor structure, a tunneling layer, a top electrode, a passivation layer, and a conductive feature. The semiconductor structure has a base portion and a protruding portion over a top surface of the base portion. The tunneling layer is over a top surface of the protruding portion of the semiconductor structure. The top electrode is over the tunneling layer. The passivation layer is over a sidewall of the protruding portion of the semiconductor structure. The conductive feature is directly below the protruding portion of the semiconductor structure.

Abstract: A cleaner for silicon wafer and a method for cleaning silicon wafer are provided. The cleaner for silicon wafer is essentially consisted of 1-3 wt % of citric acid, 2.5-5 wt % of sodium bicarbonate, limonene, potassium hydroxide and water. The cleaning efficiency may be improved by using the cleaner for silicon wafer to clean the silicon wafer.

Abstract: A stand for a display device is provided and includes a housing having an accommodating groove, a hinge structure including a first board and two second boards, and a latch including an operation portion. The first board is fixed on a backboard of the display device and has a positioning groove. The two second boards are rotatably connected respectively to two ends of the first board and each is fixed on the housing. The latch is flexibly placed on the housing and is aligned with the first board. The operation portion is exposed through the accommodating groove. The fastening portion is selectively engaged with the positioning groove by releasing a spring force of a spring connected to the latch. When the operation portion is moved in a direction away from the first board, the fastening portion is disengaged from the positioning groove by compressing the spring.

Abstract: A method for focusing by using a pre-flash is provided. The method includes the following steps. First, the image sensor captures a first image of the object, wherein the average brightness of the first image is calculated to be Y0. Next, the image sensor captures a second image of the object with the aid of a first pre-flash having a first energy, wherein the average brightness of the second image is calculated to be Y1. Afterwards, the image sensor captures a third image of the object with the aid of a second pre-flash having a second energy, wherein the average brightness of the third image is calculated to be Y2. Then, the distance D to the object is calculated according to the brightness Y0 and the difference ?Y between Y1 and Y2. Finally, the image sensor adjusts the focus according to the distance D.
