Abstract: A probe head includes a probe seat, a first spring probe penetrating through upper, middle and lower dies of the probe seat for transmitting a first test signal, and at least two shorter second spring probes penetrating through the lower die for transmitting a second test signal with higher frequency. Two second spring probes are electrically connected in a way that top ends thereof are abutted against two electrically conductive contacts on a bottom surface of the middle die electrically connected by a connecting circuit therein. The lower die has a communicating space and at least two lower installation holes communicating therewith and each accommodating a second spring probe partially located in the communicating space. The probe head is adapted for concurrent high and medium or low frequency signal tests, meets fine pitch and high frequency testing requirements and prevents probe cards from too complicated circuit design.

Abstract: Pellicle-mask systems for advanced lithography, such as extreme ultraviolet lithography, are disclosed herein. An exemplary pellicle-mask system includes a mask having an integrated circuit (IC) pattern, a pellicle membrane, and a pellicle frame. The pellicle frame has a first surface attached to the pellicle membrane and a second surface opposite the first surface attached to the mask, such that the IC pattern of the mask is positioned within an enclosed space defined by the mask, the pellicle membrane, and the pellicle frame. A void is defined between the pellicle frame and the mask, where the void is defined by a portion of the second surface of the pellicle membrane not attached to the mask. The void is not in communication with the enclosed space and is not in communication with an exterior space of the pellicle-mask system.

The photomask also includes a second material layer over the first material layer, the second material layer providing a second outer surface of the photomask. The two outer surfaces are substantially in parallel and a distance between the two outer surfaces along a first axis perpendicular to the two outer surfaces defines a thickness of the photomask. Also, the two outer surfaces are connected by a plurality of sides, at least one of the sides is not perpendicular to the two outer surfaces and the at least one of the sides provides substantial area for holding the lithographic photomask.
