Abstract: In the thermal gas pressure gauge, a foil heater has a heater surface disposed in gas communication with the gas to be measured and the heater surface is thermally cycled at first and second reference frequencies to produce cyclical heating of the gaseous material adjacent the heating element. A directional microphone is disposed facing the heating element to derive signals of an amplitude determined by the amplitude of the cyclical heating effect of the gaseous material at the first and second reference frequencies. The detected signals are synchronously detected to produce a pair of dc outputs indicative of pressure in two respective pressure regimes. In an overlap pressure regime the two dc outputs are converted to digital signals which are correlated with pairs of values tabled in a read only memory for reading out a digital signal indicative of the pressure. In a low pressure regime from approximately 10.sup.-4 torr and below to the region of 1 to 10 torr, the measured pressure is independent of the molecular gas species and therefore is an absolute gauge, whereas in the higher pressure regime from 1 to 10 torr to the condensation pressure of the measured gas, the measured pressure is somewhat dependent on the molecular gas species. For measurement in the higher pressure regime, the heater and microphone are contained within a volume of the gas separated from the relatively large volume of a chamber being measured by means of an acoustic filter. The acoustic filter provides a high impedence to pressure waves at the second or higher reference frequency to avoid dissipation of the generated pressure wave to be measured within the large chamber volume. The tabled values in the read only memory permit a smooth transition of the gauge measurement from the first to the second regime.

Abstract: A method for forming a novel head used in magneto-optic or optical disks comprises the steps of forming a diffractive lens on one side of a glass substrate and forming air bearing surface rails on a second side of said glass substrate. The glass substrate is then cut into separate heads. In this way, many magneto-optic or optical heads can be formed simultaneously without incurring the expense of bonding lenses onto a slider. In one embodiment, coils are deposited on the substrate to generate a magnetic field during magneto-optic write operations. In another embodiment, a glass wafer having diffractive lenses formed thereon is bonded to a silicon spacer structure. The glass lenses are used to define a waveguide structure on a transparent layer on the bottom of the silicon spacer

Abstract: A microactuator and method of operation is disclosed for use in actuating valves, electrical contacts, light beams, sensors and other elements between different actuation modes. An actuator member comprised of a shape memory alloy layer is mounted on an elastic substrate, and the proximal end of the actuator member is carried by a base. The shape memory alloy material is heated through its phase change transition temperature so that it deforms by changing volume to bend the distal end of the actuator member in a first direction relative to the base. Stress forces in the substrate oppose the bending movement, and when the shape change layer is cooled below the transition temperature the stress forces move the distal in a second direction which returns the shape change layer to its low temperature shape. Electrostatic forces are selectively applied between the actuator member and base for clamping the actuator member in one of its positions. In another embodiment a bistable actuator is provided in which the actuator member can be operated between two stable positions.

Abstract: A miniature transducer having an ultrathin tensioned silicon diaphragm so as to be responsive to extremely small changes in pressure. A silicon wafer is masked to define diaphragm areas, and etched to form a setback or capacitor gap a predefined depth. The mask is removed, and the entire silicon wafer is etched a second time to achieve the desired diaphragm thickness. The first and second etches are carried out independently, and thus the capacitor gap and diaphragm thickness can be independently formed. Mask and metallizing steps are carried out on glass wafers, and sandwiched around the processed semiconductor wafer, whereupon a large number of the miniature transducers are fabricated simultaneously. Unique patterning, etching and metallizing steps carried out on the sandwich structure allow a number of quadrature unit cells to be formed, thereby maximizing the area of the semiconductor and glass structures. By proper selection of materials, the diaphragm is tensioned during the fabrication of the transducer structures.

Abstract: Miniature thermal fluid flow sensors of the airfoil type are made in batch form by forming the thermal fluid flow sensors on a thin sheet of material and bonding the sheet over an array of duct structures and dicing the individual sensors and duct structures apart. In another embodiment, thin carrier sheet portions of a wafer bearing the thermal fluid flow sensors of the airfoil or grid type are supported by surrounding frame portions of the wafer. The wafer is diced to separate the individual sensing chips. The respective chips are mounted across respective fluid flow ducts. For the airfoil type sensor, portions of the frame are broken away for undisturbed flow over the thin carrier and sensor. In one thermal flow sensor configuration, a flow heater is disposed in between first and second thermal flow sensors in heat exchanging relation therewith. A third thermal flow sensor is disposed upstream of the others out of heat exchanging relation with the heater for operation of the heater at a certain temperature above that sensed by the third sensor. In the low flow regime, flow is measured by the difference between the outputs of the first and second sensors, whereas in the high flow regime, the power required to maintain the temperature of the heater serves as a measure of the flow.

Abstract: Solid state folded leaf spring force transducers are fabricated by batch photolithographic and etching techniques from a monocrystalline material, such as silicon. The folded leaf spring structure includes elongated gaps separating adjacent leaf spring leg portions, such elongated gaps being oriented parallel to a crystallographic axis of the monocrystalline material. In a preferred embodiment the monocrystalline material is of diamond cubic type and the leaf spring gaps extend in mutually orthogonal directions parallel to the and crystallographic axes, respectively. In a preferred method of fabricating the spring structure, the structure is etched from a monocrystalline wafer by means of an anisotropic etchant so as to more precisely define angles and dimensions of the resultant spring structure. In one embodiment, the gaps between adjacent leg portions of the spring structure are sealed in a fluid tight manner by means of oxide membranes left intact upon etching of the spring structure. In an accelerometer embodiment, sensing masses of equal weight are affixed to opposite sides of the spring structure for dynamically balancing same.

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.
