    摘要: 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.

    摘要: Certain MEMS devices include layers patterned to have tapered edges. One method for forming layers having tapered edges includes the use of an etch leading layer. Another method for forming layers having tapered edges includes the deposition of a layer in which the upper portion is etchable at a faster rate than the lower portion. Another method for forming layers having tapered edges includes the use of multiple iterative etches. Another method for forming layers having tapered edges includes the use of a liftoff mask layer having an aperture including a negative angle, such that a layer can be deposited over the liftoff mask layer and the mask layer removed, leaving a structure having tapered edges.

    摘要: Bit line connections for non-volatile storage devices and methods for fabricating the same are disclosed. At least two different types of bit line connections may be used between memory cells and bit lines. The different types of bit line connections may be structurally different from each other as follows. One type of bit line connection may include a metal pad between an upper via and lower via. Another type of bit line connection may include an upper via and lower via, but does not include the metal pad. Three rows of bit line connections may be used to relax the pitch. For example, two rows of bit line connections on the outside may have the metal pad, whereas bit line connections in the middle row do not have the metal pad.

    摘要: Methods for forming patterns having triple the line frequency of a first pattern using only a single spacer are disclosed. For example, the first pattern is formed in a first and a second material using a lithographic process. Sidewall spacers are formed from a third material adjacent to exposed sidewalls of features in the second material. The width of the features in the first pattern in the first material is reduced. For example, the width is reduced to about the target width of features in a final pattern. The width of features in the first pattern in the second material is reduced using remaining portions of the first material as a mask. A second pattern is formed based on remaining portions of the second material and the sidewall spacers. The features in the second pattern may be lines having about ⅓ the width of lines in the first pattern.
