Abstract: A multilayered flexible circuit board (FCB) may be fabricated by folding a single panel made of a substrate having conducting regions separated by a folding region. After conducting layers with patterned circuit areas are positioned on a single panel, the panel is folded to thereby cause one portion of the panel to stack atop the other portion of the panel and create the multilayered FCB. The multilayered FCB may have three, four, five, six, seven or eight conducting layers stacked upon one another.

Abstract: Le dispositif (1) comprend une plaque (2) de matériau diélectrique comportant des orifices (5) traversants et recouverte, sur chacune de ses faces principales (3, 4) : d'une première couche (9a, 9b) de faible résistivité, présentant des trous (10) disposés en correspondance des orifices de la plaque; et d'une deuxième couche (12a, 12b) de forte résistivité, disposée sur la première couche, et présentant des trous (13) disposés en correspondance des orifices de la plaque. Au moins un de ces dispositifs est placé entre deux électrodes créant entre elles un champ électrique. Les électrons générés par le rayonnement ionisant sont entraînés par le champ électrique, multipliés par avalanches dans les orifices de la plaque puis détectés par l'électrode de plus fort potentiel. Ce système de détection peut fonctionner dans l'air de façon stable à des gains importants.

Abstract: A method and apparatus for extracting for quantitative analysis ions of selected atomic components of a sample (14). A lens system (46, 50, 54) is configured to provide a slowly diminishing field region for a volume containing the selected atomic components, enabling accurate energy analysis of ions generated in the slowly diminishing field region. The lens system (46, 50, 54) also enables focusing on a sample (14) of a charged particle beam, such as an ion beam (18), along a path length perpendicular to the sample and extraction of the charged particles (88) along a path length also perpendicular to the sample (14). Improvement of signal to noise ratio is achieved by laser excitation of ions to selected autoionization states before carrying out quantitative analysis. Accurate energy analysis of energetic charged particles is assured by using a preselected resistive thick film configuration disposed on an insulator substrate for generating predetermined electric field boundary conditions to achieve for analysis the required field potential. The spectrometer also is applicable in the fields of SIMS, ISS and electron spectroscopy.

Abstract: The present disclosure is directed, in part, to a method for fabricating a low-stress, ultra-thin membrane as well as the low-stress, ultra-thin membrane formed by this method. The method includes: layering a first layer on a semiconductor substrate; etching a hole in the first layer; layering a second layer on the membrane of the first layer and over the hole; and etching the substrate beginning from the bottom surface thereof, such that at least a portion of the substrate aligned with the hole in the first layer is removed. The first and second layers are made of substantially the same material, which will usually be silicon nitride, however, it is contemplated that other dielectric materials could be used, but it is preferred that the second layer has an amorphous structure. It is preferred that the second layer be formed with a slightly bubble-shape to help deflect stresses on the second layer. Generally, low pressure chemical vapor deposition will be used to create at least the first and second layers. As a result of this basic method, the second layer has an ultra-thin thickness. Among other devices, the ultra-thin membrane is useful in a device for detecting physical characteristics of a sample bombarded with electrons. In such a device, the ultra-thin, low-stress membrane is positioned adjacent a electron detector. The device may further include an evacuated chamber at least partially bounded by the ultra-thin low-stress membrane.
