Abstract:
A process solution supply system and method for advantageously supplying process solution are provided. A process solution supply device provides process solution at a controlled temperature to a processing unit for injection of the process solution onto substrates through a plurality of nozzles. The process solution is transported to the nozzles through a pathway, which in one example can include a piping arrangement. The pathway advantageously uses temperature control through contact piping, a thermo-sensor, and piping arrangement, such that the process solution injected through the plurality of nozzles is substantially equal to the temperature of the process solution originally supplied from the process solution supply device.
Abstract:
A stackable semiconductor chip package, methods of fabricating the chip package, and a stacked semiconductor chip module are disclosed. In the chip package or the chip module, lateral surfaces of each semiconductor chip are insulated with insulation regions that are formed while the chip is still part of an uncut wafer. The fabrication methods include the steps of: preparing an uncut wafer having multiple chip portions; forming slots along a pair of opposed lateral sides of the chip portions; filling the slots with an insulating material; forming a first insulation layer on an upper surface of the wafer; forming via holes in the first insulation layer so that chip pads formed in each chip portion are exposed through the via holes; forming a plurality of conductive patterns on the first insulation layer so that the conductive patterns are electrically coupled to the chip pads through the via holes; forming a second insulation layer on the conductive patterns and the first insulation layer; and cutting the wafer along the cutting lines. In alternate methods, two or more wafers may be stacked before the cutting step is performed. This results in the formation of multiple stacked chip modules.

Provided is a method for manufacturing a printed circuit board. The method for manufacturing a printed circuit board includes preparing an insulation board, irradiating a laser onto a graytone mask to each a surface of the insulation board, thereby forming a circuit pattern groove and a via hole at the same time, and filling the circuit pattern groove and the via hole to form a buried circuit pattern and the via. Thus, the circuit pattern groove and the via hole may be formed using the graytone mask at the same time without perfolining a separate process for forming the via hole. Therefore, the manufacturing process may be simplified to reduce the manufacturing costs.

Provided are a wire grid polarizer and a backlight unit using the wire grid polarizer. The wire grid polarizer comprises a first grid layer formed on a substrate and provided with at least one of a first grid pattern, and a second grid layer formed on the first grid pattern and provided with at least one of a second grid pattern made of metal material wherein the first grid layer is made of high molecular substance having a lower refraction index than that of the substrate. By forming a first grid pattern on a substrate using a high molecular substance layer and by forming a metal grid pattern on the first grid pattern, transmission rates of respective wavelengths depending on light angles of incident light are controlled and thereby minimize color variations depending on view angle.
