Abstract
Ein Stapelmodul für Chips enthält wenigstens ein Substrat (20a), auf dem auf beiden Seiten wenigstens ein Chip (21a, 21b) befestigt ist und zum Schutz vor der Umgebung gekapselt ist, wodurch die Herstellungsdauer verringert wird, Material für das Substrat und die Anschlüsse eingespart wird und die Höhe des Stapelmoduls erheblich verringert wird. Ferner kann die Unterseite des Substrats (20a) auf einer Oberseite eines ähnlichen Substrats (20b) gestapelt werden, wobei auf beiden Seiten Chips (21a, 21b, 21c, 21d) befestigt und zum Schutz vor der Umgebung gekapselt sind mittels Anschlüssen (23a, 23b) zwischen den Substraten (20a, 20b), wodurch ein Stapelmodul aus mehreren Schichten gebildet wird.
Description
Die Erfindung bezieht sich auf eine Verbesserung der Struktur eines Stapel
moduls für Chips und insbesondere auf eine Struktur, die wenigstens ein Sub
strat enthält, das mit einem Chip an seiner Oberseite und seiner Unterseite
versehen ist und ermöglicht, zwei oder mehr Substrate zu stapeln, um ein
Modul zu bilden.
Wie in den Fig. 1 und 3 gezeigt, enthält das herkömmliche Stapelmodul von
vier Schichten 1A für Chips vier Substrate 10a, 10b, 10c und 10d, auf deren
Oberseiten jeweils Chips 11a, 11b, 11c und 11d montiert sind, die anschlie
ßend gekapselt werden, um sie vor der Umgebung zu schützen. Anschließend
werden die Anschlüsse 13a, 13b und 13c jeweils zwischen den Substraten 10a
und 10b, 10b und 10c, 10c und 10d angeordnet, wobei die Anschlüsse 13d an
der Unterseite des Substrats 10d befestigt werden, um eine Packung von vier
Chips zu bilden.
In ähnlicher Weise kann der Chip 11e an der Unterseite des Substrats ange
bracht sein (siehe Fig. 2), um ein Stapelmodul zu bilden.
Das herkömmliche Stapelmodul verwendet jedoch nur eine einzelne Seite des
Substrats, um einen Chip zu montieren, so daß dann, wenn mehrere Substrate
aufeinander gestapelt werden, das Stapelmodul ein großes Volumen erreicht,
wodurch es für die Verwendung in einer Vorrichtung mit geringer Höhe, wie
z. B. einem Notebook-Computer, einem Mobiltelephon, einem persönlichen
digitalen Notizbuch (PDA) oder einer Digitalkamera, ungeeignet wird.
Ferner müssen die Chips zuerst am Substrat angebracht werden und durch
Kapselung vor der Umgebung geschützt werden, woraufhin die Anschlüsse
auf dem Substrat montiert werden, bevor das Substrat auf einem ähnlichen
Substrat gestapelt wird, was bei der Herstellung sehr unbequem ist und die
Produktionsrate senkt.
Es ist daher die Aufgabe der Erfindung, die Nachteile des obenerwähnten
Standes der Technik zu beseitigen und eine verbesserte Struktur eines Stapel
moduls für Chips zu schaffen.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Stapelmodul für Chips,
das die Anspruch 1 angegebenen Merkmale besitzt. Der abhängige Anspruch
ist auf eine bevorzugte Ausführungsform gerichtet.
Weitere Merkmale und Vorteile der Erfindung werden deutlich beim Lesen
der folgenden Beschreibung bevorzugter Ausführungsformen, die auf die
beigefügten Zeichnungen Bezug nimmt; es zeigen:
Fig. 1 die bereits erwähnte Schnittansicht eines Stapelmoduls für Chips
des Standes der Technik;
Fig. 2 die bereits erwähnte Schnittansicht eines weiteren Stapelmoduls für
Chips des Standes der Technik;
Fig. 3 die bereits erwähnte Schnittansicht eines Stapelmoduls des Standes
der Technik mit zwei Schichten;
Fig. 4 eine Schnittansicht eines Stapelmoduls mit zwei Schichten gemäß
der Erfindung; und
Fig. 5 eine Schnittansicht eines Stapelmoduls mit einer einzelnen Schicht
gemäß der Erfindung.
Wie in den Zeichnungen und insbesondere in Fig. 4 gezeigt, umfaßt das Sta
pelmodul 2A gemäß der Erfindung mehrere Substrate (in dieser bevorzugten
Ausführungsform zwei) 20a und 20b. Ein Chip 21a ist an der Oberseite des
Substrats 20a befestigt, während ein weiterer Chip 21b an der Unterseite des
Substrats 20b befestigt ist. In ähnlicher Weise sind die Chips 21c und 21d an
der Oberseite und der Unterseite des Substrats 20b befestigt. Anschließend
werden die Chips 21a und 21b, 21c und 21d gekapselt, um diese vor der Um
gebung zu schützen. Anschließend werden die Anschlüsse 23a zwischen der
Unterseite des Substrats 20a und der Oberseite des Substrats 20b eingesetzt,
während die Anschlüsse 23b an der Unterseite des Substrats 20b angebracht
werden, wodurch ein Stapelmodul für Chips gebildet wird.
Es ist jedoch zu beachten, daß die Chips an der Oberseite des Substrats befe
stigt und gleichzeitig gekapselt werden können, wenn die Chips an der Unter
seite des Substrats befestigt und vor der Umgebung geschützt gekapselt wer
den, wodurch die für den Produktionsprozeß erforderliche Zeitspanne redu
ziert werden kann.
Wie in Fig. 5 gezeigt, umfaßt das Stapelmodul 2B gemäß der Erfindung ein
einzelnes Substrat 20a, auf dessen Oberseite und Unterseite die Chips 21a
bzw. 21b befestigt sind, so daß ein Stapelmodul 2B mit einer einzelnen Sub
stratschicht gemäß der Erfindung verwendet werden kann, um das herkömmli
che Stapelmodul 1 C mit zwei Schichten von Substraten zu ersetzen, wodurch
die Höhe des Stapelmoduls erheblich verringert wird und Material für das
Substrat und die Anschlüsse eingespart wird und die Produktionsrate erhöht
wird.
