Abstract: The invention provides a slim type packaging structure with high heat dissipation, which is to provide a hole on the surface of a substrate, and then a die is placed inside the hole. Besides, a plurality of wire is separately connected from the die to the substrate. Alternatively, a heat-dissipating panel with good conductivity can be placed inside the hole, and then the die is placed on the heat-dissipating panel. Thus, after the substrate is soldered on the circuit board, a direct heat-dissipating path can be formed between the die and the circuit board; therefore, the die can dissipate heat without passing through the substrate. Hence, the slim type packaging structure with high heat dissipation provided by the invention can achieve double effects of good heat dissipation and package volume slimming as well as have the advantages of low cost and simple design.

Abstract: An image processing device includes a peripheral circuit and an AFE device. The peripheral circuit is coupled to a display card, and the display signals may be inputted to the AFE device, which processes the display signals, via the peripheral circuit. The image signals outputted from the display card are single-ended analog signals including a red signal, a green signal and a blue signal. The AFE device receives the signals and then utilizes its red, green and blue converters to convert the signals into digital ones. It is to be noted that the red, green, and blue converters share the same ground, which is electrically connected to another ground of the peripheral circuit. Thus, the peripheral circuit and the AFE device have the same reference ground level so as to avoid the distortion caused when the image signals are converted from single-ended ones into the differential ones.

Abstract: A method for coating low viscosity materials onto a wafer to form a uniform film. After a wafer is rotated at a first rotation speed, coating solution is drizzled onto the wafer. The wafer is decelerated to a second rotation speed at a first deceleration rate to spread the coating solution. Next, the wafer is slowly decelerated to a third rotation speed at a second deceleration rate considerably lower than the first deceleration rate, so the coating solution reflows to the center of the wafer. The wafer is then quickly accelerated to a fourth rotation speed at a third acceleration rate larger than the first deceleration rate to spread the coating solution again.
