    Abstract: 邊緣特徵量測系統和方法用於將物件(例如半導體晶圓)的一或更多特色進行特徵化。被特徵化的特色包括接近晶圓邊緣之阻劑層外部邊界、和接近晶圓邊緣之所欲的其他晶圓特色。在一些實施例中,藉由成像系統可發現從晶圓邊緣至阻劑層邊緣的相對距離,在該處例如繞著半導體晶圓圓周移除阻劑。在其他實施例中,發現晶圓的中心(或一個或更多阻劑層的中心),且如果想要的話,也可發現晶圓中心和一或更多阻劑層的中心之間的相對偏移。

    Abstract: Projection systems and methods with mechanically decoupled metrology plates according to embodiments of the present invention can be used to characterize and compensate for misalignment and aberration in production images due to thermal and mechanical effects. Sensors on the metrology plate measure the position of the metrology plate relative to the image and to the substrate during exposure of the substrate to the production image. Data from the sensors are used to adjust the projection optics and/or substrate dynamically to correct or compensate for alignment errors and aberration-induced errors. Compared to prior art systems and methods, the projection systems and methods described herein offer greater design flexibility and relaxed constraints on mechanical stability and thermally induced expansion. In addition, decoupled metrology plates can be used to align two or more objectives simultaneously and independently.

    Abstract: An automatically adjustable method for use in opto-acoustic metrology or other types of metrology operations is described. The method includes modifying the operation of a metrology system that uses a PSD style sensor arrangement. The method may be used to quickly adjust the operation of a metrology system to ensure that the data obtained therefrom are of the desired quality. Further, the method is useful in searching for and optimizing data that is or can be correlated to substrate or sample features or characteristics that of interest. Apparatus and computer readable media are also described.

    Abstract: A method of optimizing an optical inspection and fabrication process is herein disclosed. Images, preferably color digital images, of an object are obtained and multiple filter space representations of these images are created. Each of the representations and the channels or data that define them are analyzed separately or in combination with one another to determine which representations, combination of representations, channels, combinations of channels, data or combinations of data provide the most optimal data for analysis by optical inspection algorithms. The process may be automated in terms of the creation of image representations and/or single or multivariate analysis.

    Abstract: An apparatus for improving the signal to noise ratio of measurements of the thickness of layers in a thin film stack uses a photoacoustic measurement system that includes a time differentiation system for inducing a delay in pump beam pulses. The time differentiation system uses, among other things, a birefringent element and other elements to control the polarization of pump beam pulses. Use of the apparatus involves applying a time varying voltage to an electro-optic modulator driver and setting a time differentiation step; or, in another embodiment, applying a time varying voltage to an electro-optic modulator to induce a fixed time delay delta-t between a vertically polarized pulse and a horizontally polarized pulse. The high frequency operation of the system provides for improved determinations of film thickness.

    Abstract: A system (10) for directly measuring the depth of a high aspect ratio etched feature on a wafer (80) that includes an etched surface (82) and a non-etched surface (84). The system (10) utilizes an infrared reflectometer (12) that in a preferred embodiment includes a swept laser (14), a fiber circulator (16), a photodetector (22) and a combination collimator (18) and an objective lens (20). From the objective lens (20) a focused incident light (23) is produced that is applied to the non-etched surface (84) of the wafer (80). From the wafer (80) is produced a reflected light (25) that is processed through the reflectometer (12) and applied to an ADC (24) where a corresponding digital data signal (29) is produced. The digital data signal (29) is applied to a computer (30) that, in combination with software (32), measures the depth of the etched feature that is then viewed on a display (34).
