    • PROBLEM TO BE SOLVED: To provide a pattern forming method capable of efficiently forming a required pattern with a high degree of accuracy independently of the shape of a formed pattern.
      SOLUTION: A coating type carbon film 2 is spin-coated and baked on a semiconductor substrate 1 and a positive ArF resist film 4 is spin-coated and prebaked on the carbon film 2. The resist film 4 is exposed with ArF excimer laser light 5 and patterned by development. After EB (electron beam) curing of the resist film 4, a photosensitive polysilazane film 7 is disposed on the carbon film 2 so as to cover the resist film 4 in such a way that the pattern recesses in the resist film 4 are nearly thoroughly filled. The polysilazane film 7 is exposed overall with ArF excimer laser light 8, humidified and developed to disclose the top face of the resist film 4, thereby patterning the polysilazane film 7. The resist film 4 and the carbon film 2 are etched using the polysilazane film 7 as a mask.

    • 要解决的问题:提供一种能够独立于形成的图案的形状而以高精度有效地形成所需图案的图案形成方法。 解决方案:涂覆型碳膜2在半导体衬底1上被旋涂和烘烤,并且将正的ArF抗蚀剂膜4旋涂并预烘烤在碳膜2上。抗蚀剂膜4用ArF准分子 激光5并通过开发图案化。 在抗蚀膜4的EB(电子束)固化之后,在碳膜2上设置感光性聚硅氮烷膜7,以覆盖抗蚀剂膜4,使得抗蚀剂膜4中的图形凹部几乎完全填充 。 聚硅氮烷膜7用ArF准分子激光8整体曝光,加湿显影以公开抗蚀剂膜4的顶面,从而对聚硅氮烷膜7进行图案化。使用聚硅氮烷膜蚀刻抗蚀剂膜4和碳膜2 7作为面具。 版权所有(C)2004,JPO

    • PURPOSE:To photosensitize a resist with X-ray emission in a short time by filling oxygen in the space between the mask and a semiconductor substrate in a specimen chamber associated with an X-ray emission unit. CONSTITUTION:An X-ray generated in an X-ray generating chamber 3 is emitted through a Be window 5 and a chamber 6 filled with He gas or in vacuum to selectively transmit an X-ray mask 7 and is thus emitted to the resist 11 of a semiconductor substrate 10 in a specimen chamber 8. Thus, it can obtain the same effect as that the X-ray is emitted in vacuum by filling N2 gas in the space between the mask and the substrate, thereby reducing the cost.
    • 目的:通过在与X射线发射单元相关联的标本室中的掩模和半导体衬底之间的空间中填充氧气,在短时间内对具有X射线发射的光刻胶进行光敏化。 构成:在X射线产生室3中产生的X射线通过Be窗口5和填充有He气体的腔室6或真空中发射以选择性地透射X射线掩模7,并且因此被发射到抗蚀剂11 因此,可以获得与通过在掩模和基板之间的空间中填充N 2气体在真空中发射X射线相同的效果,从而降低成本。
