摘要： An integrated semiconductor device is formed from two fabricated semiconductor devices each having a substrate by placing an etch-resist on the substrate of the one semiconductor device, by bonding the conductors of one of the fabricated semiconductor devices to the conductors of the other fabricated semiconductor device, flowing an uncured cement (e.g. epoxy) between the etch-resist and the other substrate, allowing the cement to solidify, and removing the substrate from the one of the semiconductor devices. More specifically, a hybrid semiconductor device is formed from a GaAs/AlGaAs multiple quantum well modulator having a substrate and an IC chip having a substrate by placing an etch resist on the modulator substrate, bonding the conductors of the modulator to the conductors of the chip, wicking an uncured epoxy between the modulators and the chip, allowing the epoxy to cure, and removing the substrate from the modulator.

摘要： Each microminiature contact pad included in a dense array of pads on an electronic component contains a relatively thick layer of solder. The layer is treated to form a relatively thin brittle protective layer on the surface of the solder. The structure is then brought into contact with a contact pad in a mating array of pads on another component in a thermo-compression bonding step carried out below the melting point of the solder. In that step, the brittle layer is fractured. As a result, solid-state diffusion of conductive material occurs through fissures in the fractured layer, thereby to provide an electrical connection between mating pads on the two components.

摘要： A method for forming, and an arrangement for using arbitrary angle mirrors in substrates is disclosed. An erodible material, such as a photoresist, is applied to a substrate at a site and is exposed to radiation at that site which has a linear variation in energy at the surface of the erodible material. Due to this variation in exposure energy, a taper results in the erodible material after development. The tapered region is then etched in a manner which etches both the erodible layer and the underlying substrate. The taper in the erodible layer provides a varying attenuation during the etching process such that the taper of the erodible layer, or a multiple of it, is transferred to the substrate. In a first embodiment, a tapered reflective surface is formed in a substrate, which surface engages an optical signal and deflects it to an optical device or another surface. In a second embodiment, two tapered reflective surfaces are formed in a substrate and oriented to deflect incident light to a modulation device. In a third embodiment, an arrangement for modulating a light signal is formed by two tapered reflective surfaces. The surfaces are oriented to form a vee groove in a substrate and are coated with an active semiconductor device.

摘要： A method and apparatus for modulating an optical signal, and a method for fabricating such an apparatus, are disclosed. The modulator comprises a membrane, which consists of at least three layers, and a substrate, spaced to form an air gap. The layers of the membrane are characterized by a relationship between the refractive indices of the layers and the refractive index of the substrate. The membrane is suspended in a first position over the substrate by a flexible support arrangement. A biasing force is applied to the membrane and the substrate to create an electrostatic force to move the membrane towards the substrate to a second position. The reflectivity of the device to an optical signal changes as the membrane moves from the first position to the second position, thereby modulating the signal.

摘要： An optical demultiplexing apparatus is capable of spatially separating a multiplexed optical signal into two or more optical wavelength signals thereof. An input multiplexed optical signal present on a first plane is imaged through a color-selective grating plane to a second plane. The color-selective grating has a nonlinear change of diffraction characteristics as a function of incident wavelength to provide substantial spatial separation in the second plane between bands of wavelengths proximate to the two or more optical wavelength signals. In another embodiment, the apparatus uses a polarization-selective grating to spatially separate a polarization-multiplexed optical signal into two substantial spatially separated optical polarization signals. In other embodiments, the optical apparatus may be used as an optical signal multiplexer, splitter, or combiner.
