Patent EP-0335074-A2 (EP)
Inventor: RUDECK PAUL J
IPC: G03F9/00
Filed: 1989-01-27
Abstract: A system for making alignment marks in a semiconductor for a wafer (10) etched in alignment with and bordered by an isolation level oxide (24). A silicon wafer has a film stack of silicon dioxide and silicon nitride. A pattern of data and alignment marks are exposed on the films and the device is processed to define a pattern of alignment mark positions on the silicon substrated bordered by the isolation oxide (24). The wafer (10) is then patterned with a resist (28) covering the device region and leaving exposed the alignment mark positions. The wafer (10) is then etched to create the alignment mark pattern (trenches 32) in the wafer while the device region is protected by the resist (28). The resist (28) may then be removed and device processing continued.

Abstract: The invention relates to a method of producing imide bond-containing compounds and flame retardants comprising such compounds. The method comprises reacting an acid anhydride with an isocyanate compound in an inert solvent in the presence of a tertiary amine as catalyst. The imide bond-containing compounds thus obtained provide flammable substances with good flame resistance and at the same time themselves have good heat resistance and weather resistance. Therefore, the flame retardants comprising such compounds have a wide field of application.

Abstract: In a known apparatus for the sublimation drying of materials, a condenser chamber is connected to a drying chamber via a connection line containing a valve. Situated inside the drying chamber is a sliding mechanism for the vacuum-tight closure of vessels containing the drying substance after drying is completed. This known apparatus is disadvantageous because of great constructional volume and also because separate drives are necessary on the one hand for the valve and on the other hand for the sliding mechanism. In an apparatus according to the invention, the drives for the sliding mechanism and the valve are constructionally combined and the resulting drive unit is structurally integrated into the condenser chamber. In addition to a space-saving construction, a simpler constructional shape is also obtained as a result of the combination mentioned. <IMAGE>

Abstract: A graded frequency ultrasonic sensor [10] that compensates for frequency downshifting [32] in the body is disclosed. The outer portion [20] of the sensor's aperture is sensitive to the lower frequency returns which are a consequence of the frequency downshifting. Therefore, the invention achieves a high degree of lateral resolution. The central portion [18,59] of the sensor is made thinner than the outer portion [20,57],so that the central portion is resonant at a higher frequency than the outer portion. Lateral resolution is improved by using the largest possible aperture to receive the downshifted frequencies. Techniques for shaping graded arrays, and for applying impedance matching layers [48] are disclosed for both spherical shells [10] and linear arrays [72]. The invention can be applied to different shapes of sensors, including spherical shells [10] and linear arrays [72].

Abstract: Improved dielectrically isolated semiconductor structures especially suited for very high frequency bipolar transistors are produced by etching recesses (14) in a (e.g.,N⁺) single crystal semiconductor wafer (12), coating with a dielectric (21) and a thick polycrystalline semiconductor layer (24) to provide a support, and back lapping to expose dielectrically isolated N⁺ islands (22′) located between the original recesses (14). Depressions (55) are etched in the N⁺ islands (22′) filled with a more lightly doped (e.g., N⁻) semiconductor (62). The structure is then planarized (e.g., by lapping and etching) to give isolated single crystal islands having a surrounding N⁺ periphery (58, 59) and an N⁻ central epi region (62′) of well controlled thickness and a smooth outer surface (67) suitable for device formation. Bipolar transistors of excellent properties are formed by providing a nested base and emitter within the central region. The surrounding N⁺ periphery (58, 59) automatically provides a buried layer (58) and buried layer contact (59).

Abstract: An apparatus for producing annular fiber aggregate includes: a container including an inner cylinder and an outer cylinder disposed concentrically, whereby forming an upright cylindrical space between the inner cylinder and the outer cylinder; at leaset a pair of positive electrode and negative electrode disposed by turns and buried in the wall of the outer cylinder, parallely with respect to the axis of the upright cylindrical space; a filter member disposed at the lower portion of the upright cylindrical space; and a voltage applicator connected to the positive electrodes and the negative electrodes. Since the apparatus has the positive and negative electrodes buried in the wall of the outer cylinder, the fibers are hardly disturbed and lifted by the positive and negative electrodes even when the positive and negative electrodes are rotated relatively around the axis of the upright cylindrical space. Thus, a fiber aggregate can be obtained in which the fibers are oriented in the peripheral tangent direction uniformly and favorably, and the strength thereof in the direction perpendicular to the peripheral tangent direction has been further enhanced.

Abstract: The invention relates to controlling means for inputting functional data and actuating pulses for the digital display of an electronic instrument. Such an instrument can be a time clock, a time switch, a measuring instrument or the like, on which a plurality of functions such as, e.g., time of day, temperature, duration, operating times or alarm-clock times, air pressure and the like can be optionally represented on the display. The invention proposes a solution in which the duration for the actuation of a function key for selecting one of the aforementioned functions in order to adjust the associated display can be arbitrary. A discriminator differentiates between actuation of the function key before or during the input of setting pulses for the display. <IMAGE>

Abstract: The said loads receive their operating instructions from an electronic control unit (ECU). For test purposes, this unit is connected, in accordance with the criteria of DIN/ISO 9141, to a diagnostic computer (PC) in which the test software is stored on a corresponding carrier, for example a diskette. During a test, a shunt is inserted into the current path between direct current source (2) and load (15), which, after activation of the load to be tested by the diagnostic computer (16), generates a voltage drop dependent on the current consumption of the said load. This voltage drop is measured and compared with a load-specific nominal value in the diagnostic unit. In the case of a difference, the magnitude of this difference produces an accurate indication of the actual damage in the load or error in its function.
