    摘要: In a semiconductor device fabricating process, a copper-based metal film is formed on an insulating layer, and an insulating film is formed on the copper-based metal film. A patterned resist film is formed on the insulating film, and the insulating film is dry-etched using the patterned resist film as a mask to form a hole penetrating through the insulating film. Thereafter, a plasma treatment using an non-oxidizing gas is carried out, and furthermore, a wet treatment using a resist remover liquid is carried out, for removing the resist film and a resist surface hardened layer which was generated in the dry-etching.

    摘要: A semiconductor device washing apparatus washes a surface of a semiconductor wafer after a chemical mechanical polishing process is performed for the surface. A roll brush is placed on the surface of the semiconductor wafer so as to contact with the surface. A first chemical liquid tank contains first chemical liquid. A first exhaust nozzle sprays the first chemical liquid onto the surface of the semiconductor wafer. A second chemical liquid tank contains second chemical liquid. A second exhaust nozzle sprays the second chemical liquid onto the surface of the semiconductor wafer. The first chemical liquid and the second chemical liquid are splayed onto the surface of the semiconductor wafer on the condition that the roll brush and the semiconductor wafer are rotated.

    摘要: First and second semiconductor substrate samples formed with a first oxide layer with holes and a third semiconductor substrate sample formed with a second oxide layer having no hole are prepared. The first and the third samples are subject to the same contaminating process for contaminating the surface of the first oxide layer of the first sample and the surface within the hole, and the surface of the second oxide layer of the third sample. All of the first and second layers of the first to third samples are dissolved by the HF vapor. The dissolved solutions are collected and analyzed the amount of contaminating material contained in respective solutions. The contamination amount in the hole is derived from the first, second and third contamination amount from an equation:contamination amount in the hole =first contamination amount-second contamination amount-(surface exposing ratio.times.third contamination amount)By this, in the process of fabrication of the semiconductor product, metal contaminant within the hole can be analyzed with high sensitivity, and can monitor washing effect.
