Description
Hintergrund der ErfindungBackground of the invention
Ein Photoresist ist ein organisches Polymer, das löslich wird, wenn es Licht ausgesetzt wird. Photoresists werden in vielen Anwendungen innerhalb verschiedener Industriezweige verwendet, wie bei Halbleitern, biomedizinischen Konstruktionen, in der Holographie, Elektronik und in Nanofabrikationsindustrien. Als ein Beispiel wird ein Photoresist verwendet um dabei zu helfen, Schaltkreismuster während der Chipherstellung in der Halbleiterindustrie zu definieren. Die Verwendung eines Photoresists verhindert das Ätzen oder Plattieren in dem Bereich, den das Photoresist abdeckt (dies ist auch als Resist bekannt).One Photoresist is an organic polymer that becomes soluble when exposed to light becomes. Photoresists are used in many applications within different Industries used, as in semiconductors, biomedical Constructions, in holography, electronics and nanofabrication industries. As an example, a photoresist is used to help Circuit pattern during the Chip manufacturing in the semiconductor industry. The usage of a photoresist prevents the etching or plating in the Area the photoresist covers (this is also known as resist).
Der
Entfernung des Photoresists, allgemein als „stripping” bekannt, geht ein Plasmaveraschen, Ätzen oder
andere Herstellungsschritte voraus. Diese Schritte können das
Photoresist abbauen oder carbonisieren und lassen einen Photoresist-Rückstand
zurück,
der durch derzeitige Stripping-Verfahren schwierig zu entfernen
ist. Insbesondere erzeugt eine Ionenimplantation mit einer Dosis
von 3 × 1015 Ionen/cm2 oder
größer ein
Photoresist, das eine harte äußere Kruste
zeigt, die einen weichen Kern bedeckt.
Der
Rückstand
kann auch ein Problem darstellen.
Herkömmlicherweise wurde das Photoresist durch ein Plasmaveraschungsverfahren, gefolgt von einem Stripping-Prozeß, entfernt. Das Plasmaveraschungsverfahren verwendet O2 Plasma, das Schäden an der Unterschicht bewirken und dadurch die elektrische Leistung der darunter liegenden Halbleitervorrichtung verschlechtern kann. Der Stripping-Prozeß erfordert hohe Mengen an toxischen und/oder korrosiven Chemikalien, um photoreaktive Polymere oder Photoresist von Chipoberflächen zu entfernen.Conventionally, the photoresist was removed by a plasma ashing process followed by a stripping process. The plasma ashing method uses O 2 plasma, which can cause damage to the underlayer and thereby degrade the electrical performance of the underlying semiconductor device. The stripping process requires high levels of toxic and / or corrosive chemicals to remove photoreactive polymers or photoresist from chip surfaces.
Zur Überwindung dieser Probleme sind andere Stripping-Verfahren entwickelt worden, einschließlich organischer und/oder anorganischer Stripping-Lösungsmittel mit superkritischem Kohlendioxid (SCCO2) oder Ozon (O3) Gas. Techniken, die Resist unter Verwendung von SCCO2 entfernen, benutzen eine verdichtete CO2-Reinigungszusammensetzung, die CO2 und wenigstens ein Co-Lösungsmittel einschließt, wie ein Tensid, einen Alkohol oder ein Amin. Die Verfahren, welche SCCO2 und ein Co-Lösungsmittel verwenden, sind jedoch unfähig eine harte äußere Kruste eines Photoresists, die durch Ionenimplantation hervorgerufen wurde, aufzulösen.To overcome these problems, other stripping methods have been developed, including organic and / or inorganic stripping solvents with supercritical carbon dioxide (SCCO 2 ) or ozone (O 3 ) gas. Techniques that remove resist using SCCO 2 use a compressed CO 2 cleaning composition that includes CO 2 and at least one cosolvent, such as a surfactant, an alcohol, or an amine. However, the methods using SCCO 2 and a co-solvent are unable to dissolve a hard outer crust of a photoresist caused by ion implantation.
Ein
zweites Verfahren zur Entfernung eines Photoresists oder anderen
organischen Materials von einem Substrat, wie einem Halbleiterwafer, schließt teilweises
Eintauchen des Substrats in ein Lösungsmittel, zum Beispiel deionisiertes
Wasser, in einer Reaktionskammer ein, Injizieren eines oxidierenden
Gases, zum Beispiel Ozon, in die Reaktionskammer und Rotieren oder
anderweitiges Bewegen des Substrats durch das Lösungsmittel zum Aufbringen
eines dicken Films des Lösungsmittels über dem organischen
Bestandteil auf der Substratoberfläche und Aussetzen der lösungsmittelbeschichteten
Komponente gegenüber
Ozongas, um das organische Material von der Oberfläche zu entfernen.
Ozon verwendende Resistentfernungstechniken sind jedoch nicht fähig, eine
harte äußere Kruste
aufzulösen,
die durch einen Schritt der Ionenimplantation hervorgerufen wurde.
