    摘要: A method of fabricating multilevel semiconductor wafers including a spin-on glass planarization layer is described. Prior to sputtering of the interconnect layer and after application of the spin-on glass layer, the wafer is exposed to an intense glow discharge in such a way that it is bombarded in at least a partial vacuum with ions and/or electrons and/or photons while at a temperature that is between 400 °C and 550 °C and that is at least 25 °C higher than the temperature to which the wafer is to be subjected during the subsequent sputtering step. In this way undesirable molecules can be desorbed from the spin-on glass layer so that they do not interfere with the subsequent sputtering step.

    摘要: A method of manufacturing a semiconductor device which includes an interface between a metal layer and a barrier layer of a nitride of a refractory metal, comprising the steps of depositing the barrier layer onto a wafer at high temperature; subjecting the barrier layer to a mixture of oxygen or an oxygen-containing gas and an inert gas in the presence of a plasma at low pressure and for a time sufficient to oxidize the surface of the barrier layer; removing the oxygen-containing gas; and depositing the metal layer onto the oxidized surface without subjecting said wafer to an air break. The method permits high throughput to be achieved at low cost.

    摘要: Procédé de fabrication d'une tranche de semi-conducteur, comprenant: le dépôt d'une première couche de matériau d'interconnexion sur un substrat; l'attaque du matériau d'interconnexion pour former des circuits d'interconnexion; la réalisation d'une première métallisation pour déposer une première couche diélectrique à basse température au-dessus des circuits d'interconnexion; l'aplanissement de la première couche diélectrique à basse température au moyen de verre filé quasi-inorganique ou inorganique par un procédé contraire à la gravure en retrait; le dépôt d'une deuxième couche diélectrique à basse température au-dessus du verre filé, la réalisation d'une désorption in-situ physique et chimique de vapeur d'eau dans une ambiance sèche à une température d'au moins 400 °C et non supérieure à 550 °C pendant une durée suffisante pour obtenir un taux de désorption négligeable, la température dépassant d'au moins 25 °C la température à laquelle la surface de la tranche sera exposée pendant une étape de métallisation ultérieure; la gravure de trous de transit à travers les couches de verre filé et diélectrique pour atteindre les circuits de la première couche d'interconnexion et la réalisation de l'étape de métallisation ultérieure pour déposer une deuxième couche d'interconnexion passant par les trous de transit vers les premiers circuits d'interconnexion tout en maintenant l'ambiance sèche. Les étapes ultérieures de gravure et de métallisation suivant l'étape de désorption sont effectuées sans re-exposer la tranche aux conditions ambiantes. Cette technique permet d'utiliser avec fiabilité des verres filés inorganiques et quasi-inorganiques dans un équipement de pulvérisation sans charge.

    摘要: A method of manufacturing a semiconductor wafer, comprises depositing a first layer of interconnect material on a substrate, etching the interconnect material to form interconnect tracks, performing a first metallization to deposit a first low temperature dielectric layer over the interconnect tracks, planarizing the first low temperature dielectric layer with quasi-inorganic or inorganic spin-on glass by a non-etchback process, depositing a second low temperature dielectric layer over the spin-on glass, performing an in-situ desorption of physically and chemically water vapour in a dry environment at a temperature of at least 400 °C and not more than 550 °C for a time sufficient to obtain a negligible desorption rate, the temperature exceeding by at least 25 °C the temperature to which the surface of the wafer will be exposed during a subsequent metallization step, etching via holes through the dielectric and spin-on glass layers to reach the tracks of the first interconnect layer, and performing the subsequent metallization step to deposit a second interconnect layer extending through the via holes to the first interconnect tracks while maintaining the dry environment. The subsequent etching and metallization steps after the desorption step are performed without re-exposure of the wafer to ambient conditions. This technique permits the reliable use of inorganic or quasi-inorganic spin-on glasses in non batch type sputtering equipment.
