Abstract

The invention provides an integrated photoelectric receiving module containing a low noise amplifier and a production process thereof. The module adopts the design of a hybrid integration structure ofa high-speed photodiode die and a low noise amplifier chip; compared with a split structure, the structure has the advantages that the size is reduced, the radio frequency performance is improved andthe reliability is improved. The hybrid integration process is a common-substrate micro-assembly process and the high-speed photodiode die, the low noise amplifier chip and micro-strip lines are aligned, bonded and baked at a time through an epoxy silver glue process, and the process is simple, the process time is reduced and the process efficiency is high; a hybrid integration circuit substrateis made of AlN substrate material with good surface finish and high thermal conductivity; the hybrid integration circuit substrate adopts a thin film circuit process and a gold wire wedge welding process is utilized for welding, so that the influence of parasitic inductance is effectively reduced and the requirement of high-speed module packaging is better satisfied; the whole packaging structureis simple and practical in design, is high in process production feasibility and is suitable for batch production.

Description

technical field [0001] The invention belongs to the technical field of semiconductors, and relates to the design and production process of an integrated photoelectric receiving module containing a low-noise amplifier. Background technique [0002] With the continuous development of microwave photonics technology, radar and electronic warfare systems based on microwave photonic link architecture have been developed rapidly and widely used. The broadband analog optical receiving module is used for the reception and detection of broadband analog optical signals in radar and electronic warfare systems, and is one of the core components of the microwave photonic link.
