摘要： The connection topology of input terminals (2), elements (4a, 4b, 4c and 4d) and load (5) is designed similarly to a “seven-segment display” that is often used to display numerals on a calculator or a digital watch. Specifically, suppose in the three horizontally running segments of the seven-segment display, the top and bottom ones are associated with the input terminals (2) and the load (5) is allocated to the other horizontal one. Then, the other four vertical segments are associated with the elements (4a, 4b, 4c and 4d), which may be an inductor with an inductance of 4.030 nH, an inductor with an inductance of 11.208 nH, an inductor with an inductance of 2.497 nH, and a capacitor with a capacitance of 2.233 pF, respectively. By adopting this circuit configuration, the total number of elements can be reduced to four and the loss can be reduced significantly. Since the resonant circuits can be eliminated and the size of the ladder circuit can be reduced, impedance matching is achieved with a high degree of stability in spite of a variation in the impedance of the load (5).

摘要： A millimeter wave module includes a silicon substrate with first and second cavityes formed by anisotropic etching on the silicon substrate, and a glass substrate having a microstrip filter pattern and microbumps for connecting the glass substrate to the silicon substrate. A filter is provided using an air layer as a dielectric disposed in the first cavity. An MMIC is mounted by the flip chip method over the second air layer. A coplanar waveguide is on the silicon substrate for connecting the filter and MMIC. The filter having low loss is achieved because it has the microstrip structure using air as an insulating layer. Also change in characteristics of the MMIC during mounting is eliminated because the MMIC is protected by contacting air. Accordingly, the millimeter wave module has excellent characteristics and is made using a simple method.

摘要： A circuit assembly having a thin and large-area dielectric substrate and improved grounding. To make the assembly, a circuit board comprising the substrate, and a circuit pattern and a metal layer that are formed on respective sides of the substrate. A bath of conductive bonding material (e.g., a low melting point solder) is made inside a tray-like metal chassis of the assembly. The circuit board is floated on the bath and excessive portion of the conductive material is absorbed. A branch circuit for branching a first path into at least two second paths is provided by mainly using impedance transformers but by using fewest possible stub(s). Also, the elements are arranged in symmetry around the axis through the first path. This yields a wide operating frequency band. A waveguide-microstrip line transition that is easy to work and low in transition loss is provided by shaping the wider walls of the ridge waveguide so as to spread out toward the end. Since doing this increases the degree of freedom in design parameters, the width and the height of the ridge can be fitted to that of the microstrip line and that of the waveguide. The above elements is applicable to HF circuits, antennas and communication systems.

摘要： An alignment apparatus for use in an exposure system for exposing fine patterns on a wafer, the alignment apparatus comprising a light source optical system for emitting coherent alignment light, a positional deviation detecting optical system for receiving the alignment light reflected from the wafer, and a light-receiving optical system for detecting a positional deviation of the wafer on the basis of the alignment light received by the positional deviation detecting optical system. These three optical systems are arranged to be coupled through flexible optical fibers to each other. This coupling arrangement using the flexible optical fiber can reduce the size of the positional deviation detecting optical system whereby the positional deviation detecting optical system can be disposed directly under a projection lens of the exposure system, thereby accurately effecting the alignment of the wafer with respect to the projection lens.
