Description
- 1. Einige spezifische Methoden zur Trennung von Schichten im Bereich der Halbleitertech nologie wurden bereits patentiert oder veröffentlicht
- (i) Im Materialsystem GaAs/AlAs werden im Herstellungsprozeß der Bauelemente AlAs Opferschichten implementiert, die naßchemisch aufgelöst werden können. Dies ermög licht die Trennung von Schichten oder Strukturen vom Substrat (E. Yablonovitch et aL, Appl. Phys. Lett. 51, 2222 (1987), U.S. Patent 4,846,931, Thomas J. Gmitter and E. Yablonovitch, 11. Juli 1989). Diese Methode ist wegen der geringen lateralen Ätzge schwindigkeit sehr zeitaufwendig. Für Gruppe III-Nitride gibt es keine naßchemische Ät zen.
- (ii) Eine Methode zur Entfernung von Metallfilmen wurde von Baber beschrieben (U.S. Patent 4,448,636, S.C. Baber, 15. Mai 1984). Hierbei wird der Metallfilm durch Licht erhitzt. Eine organische Opferschicht zwischen Substrat und Metallfilm wird durch die zugeführte Wärme verdampft und erlaubt die Entfernung der Metallschicht. Die Ver wendung von organischen Zwischenschichten ist bei dem epitaktischen Wachstum von Gruppe III-Nitriden nicht einsetzbar.
- (iii) Eine vergleichbare Methode wurde zur Entfernung von Siliziumdioxid-Schichten von Galliumarsenid beschrieben. Auch in diesem Falle wurde eine organische Zwischen schicht durch Lichtabsorption erhitzt und die SiO₂ Schicht abgehoben (Y.-F. Lu, Y. Aoyagi, Jpn. J. Appl. Phys. 34, L1669 (1995)).
- (iv) Von der gleichen Arbeitsgruppe existiert eine Veröffentlichung über die Separation von SiO₂ Streifen von GaAs mit Hilfe eines Excimer-Lasers. Die mikroskopische Wirkungs weise des Excimer Laserlichts auf die Grenzfläche des SiO₂ blieb unverstanden und ist spezifisch für dieses Materialsystem (Y.-F. Lu et al., Jpn. J. Appl. Phys. 33, L324 (1994)). Diese Verfahren lassen sich jedoch nicht offensichtlich auf Gruppe III-Nitride oder andere kristalline Systemen übertragen.
- 2. Laser Ablation ist auf viele Materialsysteme angewandt worden um Material zu entfer nen. Jedoch wird bei dieser Methode immer die Oberfläche destruktiv abgetragen, eine Trennung in zwei weiter zu verwendende Teile ist nicht möglich.
- 3. Spezifisch für Gruppe III-Nitride ist das Ätzen von GaN mit einem Laserpuls unter HCl-Gas von Leonard und Bedair (Appl. Phys. Lett. 68, 794 (1996)) beschrieben worden und auf eine photochemische Reaktion unter Beteiligung von Salzsäure zurückgeführt worden.
- 4. Die thermisch aktivierte Zersetzung von GaN wurde durch Morimoto 1974 beschrieben (Morimoto, J. Electrochem. Soc. 121, 1383 (1974), Groh et al., physica status solidi (a) 26, 353 (1974)).
- 5. In eigenen Arbeiten wurde gezeigt, daß Gruppe III-Nitride laserinduziert zu thermisch aktivierter Zersetzung gebracht werden können. Diese Untersuchung ist bei Appl. Phys. Lett. zur Publikation eingereicht worden. Es handelt sich bei diesem Verfahren jedoch ebenfalls um ein auf die Oberfläche wirkendes Verfahren, daß insbesondere auch zu der Zerstörung der Oberfläche führt.
- (i) die Identifizierung, Auswahl oder Herstellung einer zu trennenden Grenzfläche in dem gewünschten Schichtsystem, welche mit dem zur Trennung zu benutzenden Licht er reichbar ist,
- (ii) die Identifizierung eines Materials, oder Einbau eines Materials als Opferschicht an der Grenzfläche, das das eingestrahlte Licht absorbiert.
- (iii) die Identifizierung eines Materials, oder Einbau eines Materials als Opferschicht in der Grenzflächennähe, das durch das absorbierte Licht oder daraus resultierende Energie zur Zersetzung gebracht werden kann und womöglich bei der Zersetzung ein gasförmiges Produkt in ausreichender Menge erzeugt.
- (iv) die Beleuchtung mit Licht einer ausgewählten Wellenlange und Intensität, so daß das Licht hauptsächlich von der zu trennenden Grenzfläche oder der Opferschicht absorbiert wird und dabei die Zersetzungsreaktion anregt, wobei im Falle transparenter Substrate die Grenzfläche oder Opferschicht auch durch das Substrat hindurch beleuchtet werden kann.
