Abstract

PURPOSE:In a hybrid IC where bare chips are mounted, to mount a bare chip on another side too thereby promoting high density, high integration, and miniaturization by providing a cavity at one side of a board so as to bury a bare chip in the cavity. CONSTITUTION:A pellet 7 is mounted with Ag paste in the cavity of an insulating substrate 9 having said cavity at one side, and is bonded with a gold wire 8, and then precoat resin 6 is poured in the cavity. But care shall be taken so that it may no protrude. After completion of the mounting, bonding, and precoating works at the side where the cavity exists, a pellet 7 is mounted with Ag paste similarly on the side without cavity, and is bonded. After application of precoating resin 6, printing is done with solder pate 5 on the side where the cavity exists, and a miniflat 1, a chip capacitor 2, and a minimold are mounted. After mounting discrete parts on the side where the cavity exists, printing is done similarly with a solder paste 5, and a miniflat 1, a chip capacitor 2, and a minimold are mounted.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、混成集積回路に関し、特に絶縁基板上にベア
チップ搭載する構成をもつ混成集積回路に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hybrid integrated circuit, and particularly to a hybrid integrated circuit having a configuration in which a bare chip is mounted on an insulating substrate.

〔従来の技術〕[Conventional technology]

近年、装置の小型化への要求から回路の集積が大幅に進
められてきており集積規模が大きくなるにつれＩＣで補
えきれない回路が多く発生する。In recent years, the integration of circuits has been greatly advanced due to the demand for miniaturization of devices, and as the scale of integration increases, many circuits that cannot be replaced by ICs are generated.

そのためＩＣの補助回路として混成集積回路がますます
必要性１重要性を増してくる。混成集積回路は、絶縁基
板（例えばセラミック基板）上に導体膜、抵抗膜などを
形成し能動素子であるＩＣ。Therefore, the necessity and importance of hybrid integrated circuits as auxiliary circuits for ICs is increasing. A hybrid integrated circuit is an IC that is an active element and has a conductive film, a resistive film, etc. formed on an insulating substrate (for example, a ceramic substrate).

搭載し、受動素子である抵抗およびコンデンサは厚膜・
薄膜で形成しあるいはチップ部品で搭載する。Equipped with transistors, diodes, and passive elements such as capacitors, coils, and resistors, they provide various circuit functions and are used in many fields such as communication devices and central processing units for computers. In conventional hybrid integrated circuits, ICs are mounted as discrete components or pellet products on an insulating substrate, and passive elements such as resistors and capacitors are mounted using thick films.
It is formed with a thin film or mounted with a chip component.

ティングの凹凸があるため半田印刷ができないなどの欠
点がある。The conventional hybrid integrated circuit described above achieved 4A integration by replacing discrete components with bare chip components, but bare chips can only be mounted on one side, and one side is all discrete components, so it occupies a large board area. This will hinder miniaturization. Furthermore, when discrete components are mounted on the bare chip mounting surface, there are drawbacks such as the inability to perform solder printing due to the unevenness of the bare chip protective coating.
