    • A method to provide a ground point for second, or subsequent, e-beam mask-writing steps by selectively removing the photoresist edge bead of a photomask substrate to expose the underlying chrome layer. The selective removal leaves at least one tab of photoresist edge bead over the chrome layer. After the first e-beam mask writing step and subsequent etch, the tab can be removed to expose a portion of the chromium layer that can act as a new ground point for a second e-beam etch. Also, a nozzle for use in selectively removing the edge bead to leave a tab of photoresist edge bead.
    • 通过选择性地去除光掩模衬底的光致抗蚀剂边缘以暴露下面的铬层来为第二或随后的电子束掩模写入步骤提供接地点的方法。 选择性去除在铬层上留下光致抗蚀剂边缘珠的至少一个突片。 在第一电子束掩模写入步骤和随后的蚀刻之后,可以去除突片以暴露可以充当第二电子束蚀刻的新接地点的铬层的一部分。 而且,用于选择性地去除边缘珠以留下光致抗蚀剂边缘珠的突片的喷嘴。

    • The present invention provides an attenuated phase shift mask (“APSM”) that, in each embodiment, includes completely transmissive regions sized and shaped to define desired semiconductor device features, slightly attenuated regions at the edges of the completely transmissive regions corresponding to isolated device features, highly attenuated regions at the edges of completely transmissive regions corresponding to closely spaced or nested device features, and completely opaque areas where it is desirable to block transmission of all radiation through the APSM. The present invention further provides methods for fabricating the APSMs according to the present invention.
    • 本发明提供了衰减相移掩模(“APSM”),其在每个实施例中包括尺寸和形状以确定期望的半导体器件特征的完全透射区域,在完全透射区域的边缘处对应于隔离的器件特征的略微衰减的区域 在完全透射区域的边缘处的高度衰减的区域对应于紧密间隔或嵌套的器件特征,以及完全不透明的区域,其中期望阻止通过APSM的所有辐射的透射。 本发明还提供了制造根据本发明的APSM的方法。

    • The invention includes reticles and methods of forming reticles. In one aspect, a reticle can include a quartz-containing substrate, an attenuating layer, and an antireflective structure between the attenuating layer and the quartz-containing substrate. The invention can also include a reticle having a relatively transparent region between first and second surfaces, a relatively opaque region proximate the first surface, and a layer comprising one or both of metal fluoride and hafnium oxide proximate the first or second surface. The invention can also include methods of forming reticles in which an antireflective structure is formed over a surface of a quartz-containing substrate. The antireflective structure can comprise a Fabry-Perot pair, and in some aspects can comprise a layer containing one or both of metal fluoride and hafnium oxide.
    • 本发明包括掩模版和形成掩模版的方法。 在一个方面,掩模版可以包括含有石英的衬底,衰减层和在所述衰减层和含石英衬底之间的抗反射结构。 本发明还可以包括在第一表面和第二表面之间具有相对透明区域的掩模版,靠近第一表面的相对不透明的区域,以及在第一表面或第二表面附近包含金属氟化物和氧化铪中的一种或两种的层。 本发明还可以包括在含石英衬底的表面上形成抗反射结构的形成掩模版的方法。 抗反射结构可以包含法布里 - 珀罗对,并且在一些方面可以包含含有金属氟化物和氧化铪中的一种或两种的层。
