    Abstract: A method for fabricating a magnetic head with a trapezoidal shaped pole piece tip is described. The body of the main pole piece is deposited; then one or more layers for the pole piece tip are deposited. A bed material is deposited over the pole piece tip material. A void is formed in the bed material over the area for the pole piece tip. The void is filled with an ion-milling resistant material such as alumina preferably using atomic layer deposition or atomic layer chemical vapor deposition. The excess ion-milling resistant material and the bed material are removed. The result is an ion-milling mask formed over the area for the pole piece tip. Ion milling is then used to remove the unmasked material in the pole piece tip layer and to form a beveled pole piece tip and preferably a beveled face on the main pole piece.

    Abstract: MEMS devices are fabricated by a method that involves forming an optical element (e.g., etalon) over a substrate and then forming a light modulating element (e.g., interferometric modulator) over the optical element. In an embodiment, a support structure for the light modulating element is aligned with the underlying optical element to thereby alter the appearance of the support structure to a viewer. Such an optical element is separated from the support structure by one or more buffer layers.

    Abstract: MEMS devices (such as interferometric modulators) may be fabricated using a sacrificial layer that contains a heat vaporizable polymer to form a gap between a moveable layer and a substrate. One embodiment provides a method of making a MEMS device that includes depositing a polymer layer over a substrate, forming an electrically conductive layer over the polymer layer, and vaporizing at least a portion of the polymer layer to form a cavity between the substrate and the electrically conductive layer. Another embodiment provides a method for making an interferometric modulator that includes providing a substrate, depositing a first electrically conductive material over at least a portion of the substrate, depositing a sacrificial material over at least a portion of the first electrically conductive material, depositing an insulator over the substrate and adjacent to the sacrificial material to form a support structure, and depositing a second electrically conductive material over at least a portion of the sacrificial material, the sacrificial material being removable by heat-vaporization to thereby form a cavity between the first electrically conductive layer and the second electrically conductive layer.

    Abstract: A process and apparatus are described for a projection system having improved depth of focus. This has been achieved by introducing into a standard projection system, of the type suitable for photolithography, both a quadrupole mask in the pupil plane of the illuminator lens and a phase-type filter in the pupil plane of the projection lens. Detailed data for the design of both these filters is provided. If these guidelines are followed the result is a projection system whose depth of focus has been increased to a sufficient degree to allow the formation, in a single exposure, of a photoresist wafer suitable for simultaneously etching both isolated and densely packed contact holes.
