    Abstract: A magneto optic or optical disk drive comprises a laser source for providing laser beam, and a lens or compound lens for focussing the laser onto a currently inserted recording disk with specific overcoat thickness. In one embodiment, the lens is a compound lens that can focus aberration-free spots on different types of disk media having recording layers located under overcoats of different thicknesses. When a specific disk is inserted, only one spot in focussed onto the current recording layer. Furthermore, if the disk spins rapidly, it can wobble. The lens or compound lens comprises different regions where the focal length may vary slightly and continuously or discretely. Because of this, as the disk wobbles, the lens can nonetheless continue to focus laser light onto a small spot on the recording media, providing increased depth of focus in the vicinity of the currently inserted recording media. Furthermore, the increased depth of focus will also remedy problems related to the change in focal length of the lens with changes in wavelength of the laser source. Because some of these changes in wavelength occur abruptly, this is also a case in which the limited performance of the auto-focus tracking system would be overly burdened.

    Abstract: Three dimensional single crystalline structures, such as folded cantilever beams supported from a frame and supporting a central structure free to move relative to the frame, are fabricated by anisotropically etching through openings in etch stop layers on opposite sides of the substrate wafer. The openings are patterned and aligned so that the etch stop layers are undercut to define etch stop portions interconnected by unetched substrate material.

    Abstract: A method of producing a high resolution expanded analog gray scale mask is described. Using an inorganic chalcogenide glass, such as a selenium germanium, coated with a thin layer of silver, a gray scale mask may be produced with accurate control of the size, uniformity and variance of the pixels. The selenium germanium glass is composed of column structures arranged perpendicularly to the substrate giving a possible edge precision of 100 .ANG.. The column structures also prevent undercutting during the etching process, thus permitting pixels to be placed close together. Accordingly, selenium germanium may be used as a high resolution gray scale mask with an expanded analog gray scale. The gray scale mask may be used to impress information as a modulated thickness on a selenium germanium photoresist film on an inorganic substrate. The selenium germanium photoresist film may then transfer the gray scale to the substrate.

    Abstract: Folded cantilever structures and solid state force transducers using same are made by chemical etching of a semiconductive wafer. In the chemical etching process, an etch stop layer is provided on a wafer of semiconductive material. The etch stop layer is opened in a certain pre-determined pattern and etchant is introduced through the opening in the etch stop layer to produce substantial undercut etching of portions of the etch stop layer. The opening is patterned to define a support structure (frame) for the folded cantilever portion which is undercut. The etch is terminated such that one end of the undercut folded cantilever structure is supported from the frame and the other end terminates on a structure such as a mass that is supported from the frame by means of the folded cantilever structure.

    Abstract: An etch stopped layer portion overlying a (100) or (110) major face of a diamond cubic semiconductor material is undercut anisotropically etched by orienting a side edge of the etch stopped layer portion which is to be undercut, at an angle to the most nearly parallel {111} trace on the (100) or (110) face. The etch time is further reduced by slotting through the etch stopped layer with slots oriented at an angle to the {111} traces on the underlying (100) or (110) face. Undercut bridge structures are formed by undercutting quadrilateral etch stopped layer portions from opposite sides of the quadrilateral or from the sides plus slots forming diagonals of {111} trace quadrilaterals having combined areas coextensive with the area to be undercut.

    Abstract: A capacitive force transducer, particularly suited for use as a microphone or as a phonograph needle pick-up cartridge, comprises a diaphragm electrode insulatively held to a lip portion of a recess in a second electrode, thereby forming a capacitive detector. The lip structure of the second electrode structure has a capacitive face region diverging from a virtual pivot region at the lip where the diaphragm is pivotably affixed to the recessed electrode. In this manner, the quiescent capacitance is defined predominantly by the capacitance near the lip, which is relatively small and defined and the change in capacitance for a given deflection of the diaphragm is relatively large, thereby improving the sensitivity of the transducer. In the case of a phonographic pick-up cartridge, the pick-up needle is coupled to the diaphragm so that vibrations induced in the needle produce corresponding vibrations of the diaphragm. A batch method of fabricating the transducers comprises recessing a semiconductive wafer through a major face to define a plurality of capacitive regions around the margins of the recesses. The diaphragm is conveniently formed by a layer deposited over an insulative layer deposited on the non recessed face of the wafer. The wafer is diced to provide a batch of the transducers.

    Abstract: The detector region of a gas analyzer is interfaced to a source of gas under analysis, such as the atmosphere, by means of an adsorber type preconcentrator, which preferentially adsorbs the gaseous constituent of interest, such as relatively heavy hydrocarbons, while permitting the other lighter hydrocarbons, water vapor, and permanent gases to pass thereby without appreciable adsorption. After a substantial volume of gas to be analyzed has passed through the adsorber stage, the adsorbed materials are desorbed from the surface of the adsorber into the input stage of a membrane separator. As a consequence, the partial pressure of the constituent of interest is greatly increased at the input stage of the membrane separator. The gaseous constituent of interest is then passed through the membrane separator, and further separated therein from water vapor, the permanent gases and some of the lighter hydrocarbons and then passed into the detector region of the gas analyzer. In a preferred embodiment, the output stage of the membrane separator is connected to a second adsorber concentrator so that the partial pressure at the output of the membrane separator is reduced for the gaseous constituent of interest so as to facilitate flow of the gaseous constituent of interest through the membrane separator.
