    摘要: A digital photoreceiver is formed monolithically on an InP semiconductor substrate and comprises a p-i-n photodetector formed from a plurality of InP/InGaAs layers deposited by an epitaxial growth process and an adjacent heterojunction bipolar transistor (HBT) amplifier formed from the same InP/InGaAs layers. The photoreceiver amplifier operates in a large-signal mode to convert a detected photocurrent signal into an amplified output capable of directly driving integrated circuits such as CMOS. In combination with an optical transmitter, the photoreceiver may be used to establish a short-range channel of digital optical communications between integrated circuits with applications to multi-chip modules (MCMs). The photoreceiver may also be used with fiber optic coupling for establishing longer-range digital communications (i.e. optical interconnects) between distributed computers or the like. Arrays of digital photoreceivers may be formed on a common substrate for establishing a plurality of channels of digital optical communication, with each photoreceiver being spaced by less than about 1 mm and consuming less than about 20 mW of power, and preferably less than about 10 mW. Such photoreceiver arrays are useful for transferring huge amounts of digital data between integrated circuits at bit rates of up to about 1000 Mb/s or more.

    摘要: A method of manufacturing a semiconductor device using simplified processing and eliminating and/or minimizing the extrinsic parasitic elements of the device. The method is particularly suited for manufacturing heterojunction bipolar transistors where the extrinsic parasitic base resistance and the extrinsic parasitic base-collector and base-emitter capacitances can be virtually eliminated and the base contact resistance can be greatly reduced. The method includes formming symmetric emitter and collector portions using front and backside processing of the wafer, respectively. The symmetric emitter and collector virtually eliminates the extrinsic collector and emitter regions of the device thereby virtually eliminating the extrinsic base-collector and base-emitter capacitance. The extrinsic base contact region may also be increased to minimize the base contact resistance without increasing parasitic capacitive elements of the device. Self-aligned processing features are also included to form self-aligned contacts to the base layer thereby virtually eliminating the extrinsic base resistance. The method may include building up the collector and emitter contacts to separate the emitter and collector interconnections from the base layer to avoid increasing the emitter-base and collector-base extrinsic parasitic capacitances and to minimize associated resistances and inductances. The method may further include forming etch stop layers to facilitate removing of the substrate to perform the backside processing and to accurately etch through the collector layer without etching the base layer.

    摘要: A method of manufacturing heterojunction transistors having self-aligned contacts. In manufacturing a heterojunction bipolar transistor, a collector and a base layer are deposited on a substrate. A masking layer is deposited on the base layer and selectively etched to form an aperture therein, exposing the base layer. An emitter having a mesa structure is grown epitaxially on the exposed base layer to produce lateral overhang portions. The overhang portions may be formed by continuing the epitaxial growth to form lateral overgrowth portions overlapping the masking material. The masking layer is removed and self-aligned contacts are formed to the base and emitter regions using the lateral overhang portions which provide separation between the emitter structure and the contacts to the base layer.

    摘要: A method for providing encapsulation of an electronic device which obtains an encapsulating member configured to enclose the electronic device, prepares a surface of the encapsulating member for non-adhesive direct bonding, prepares a surface of a device carrier including the electronic device for non-adhesive direct bonding, and bonds the prepared surface of the encapsulating member to the prepared surface of the device carrier to form an encapsulation of the electronic device. As such, an encapsulated electronic device results which includes the device carrier having a first bonding region encompassing the electronic device, includes the encapsulating member having at least one relief preventing contact between the electronic device and the encapsulating member and having a second bonding region bonded to the first bonding region of the device carrier, and includes a non-adhesive direct bond formed between the first and second bonding regions thereby to form an encapsulation of the electronic device. The encapsulated electronic device can be an electronic or optoelectronic device.
