Photomask plasma etching: a review

WebMetal–organic materials such as [NH2(CH2–CH═CH2)2][Cr7NiF8(Pivalate)16] can act as negative tone resists for electron beam lithography (EBL) with high-resolution patterning of sub-40 nanometer pitch while exhibiting ultrahigh dry etch selectivities >100:1 and giving line dose exposures >11,000 pC/cm. It is clear that the resist sensitivity is too low to be used … WebAbstract. While plasma etching of wafers has been a mainstay of the semiconductor industry for more than 25 years, only in the last decade has dry-etch processing become interesting to mask manufacturers. The reason for the late introduction of this technology becomes obvious when the methodologies used to image silicon wafers are examined.
