摘要:
A method of forming circuit patterns on a semiconductor wafer using two different image steppers having nonaligned optical image systems achieves optical alignment of multiple overlays with high accuracy. A first alignment mark is imaged by the first stepper onto a material layer deposited on the wafer, and a second alignment mark is imaged onto a subsequently deposited material layer using the second stepper. Alignment of the two marks, and thus of successively imaged, overlying circuit patterns, is achieved by translating the optical coordinates of the second alignment system into the those of the first alignment system, and then making corresponding two dimensional adjustment of the wafer position relative to the second stepper.

An integrated de-focus pattern provides an effective in-line monitor for photo processing steps of integrated circuit wafers. The de-focus pattern is formed on an integrated circuit wafer in the vertical and horizontal spaces between integrated circuit chips. The de-focus pattern has a number of different test patterns at different heights above the wafer surface. De-focus patterns are placed across the entire wafer surface. The de-focus patterns are formed at the same time the features of the circuit chips are formed. The de-focus patterns can be analyzed optically or using a scanning electron microscope.

A system error analysis device which includes a top unit and a storage unit coupled to the top module is mentioned. The storage unit is configured to store each of the input data, each of the output data and each of the bus data transmitted by the top unit. When receiving an interrupting signal, the system error analysis device outputs the input data, the output data and the bus data stored as soon as the interrupting signal is received and the input data, the output data and the bus data stored before the receiving of the interrupting signal. Accordingly, by comparing and analyzing the data output by system error analysis device, the system employing the system error analysis device is able to obtain the reason of the generation of the interrupting signal.

A p-type transparent conductive oxide and a solar cell containing the p-type transparent conducting oxide, wherein the p-type transparent conductive oxide includes a molybdenum trioxide doped with an element having less than six valence electrons, the element is selected from the group consisting of alkali metals, alkaline earth metals, group III elements, group IV, group V, transition elements and their combinations. Doping an element having less than six valence electron results in hole number increase, and thus increasing the hole drift velocity, and making Fermi level closer to the range of p-type materials. Hence, a p-type transparent conductive material is generated. This p-type transparent conducting oxide not only has high electron hole drift velocity, low resistivity, but also reaches a transmittance of 88% in the visible wavelength range, and therefore it is very suitable to be used in solar cells.

A frame layout and method for determining the overlay accuracy of a first chip image relative to a second chip image when the first and second chip images are used to form a single chip. One embodiment employs a vernier scale in two orthoginal directions included in the scribeline of both the first chip image and the second chip image. Another embodiment employs a box in box pattern included in the scribeline of both the first chip image and the second chip image. A layer of photoresist on an integrated circuit wafer is exposed with the first and second chip image and the associated monitor images. When the photoresist is developed the overlay accuracy of the first chip image relative to the second chip image can be determined directly from the monitor images in the photoresist.

A debounce apparatus and a method thereof are provided, which includes a debounce module, a register and a timer. The debounce module receives an input signal and eliminates a bounce phenomenon of the input signal within a transient-time of the state-changing of the input signal to produce a debounce signal. The register outputs an output signal according to the value stored in the register. When the input signal changes its state, the timer starts time-counting according to a counting-value of settling-time; when the debounce signal changes its state, the timer recounts time; and when time-counting is ended and when the value corresponding to the debounce signal is different from the register's value, the register's value is updated by the value corresponding to the debounce signal. In this way, the apparatus can eliminate the system misjudgement problem caused by occurred voltage level errors in the stable state.
