Now there are also versions with negative resists as top resist. The greatest advantage of this innovation is the higher thermal stability of negative resists. The negative two-layer system <b>SX AR-P5460\/1<\/b> + <b>SX AR-N4340\/6<\/b> yields a distinct undercut and generates straight edges in the bottom layer, which is not self-evident, given the isotropic etching behavior (see fig. 1).<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-17552\" src=\"https:\/\/www.allresist.com\/wp-content\/uploads\/sites\/2\/2022\/06\/x.png\" alt=\"\" width=\"200\" height=\"150\" \/><\/p>\n<p>Fig. 1: Undercut generated with the negative two-layer system SX AR-P5460\/1 + SX AR-N4340\/6<\/p>\n<p>For even higher temperature stress, a thermostable negative resist was developed (\u2192Temperature-stable negative resist). This resist shows promising results as top resist. In a relatively speedy manner, it was possible to optimize this two-layer development and generate the undercut. For this purpose, resists of the series <b>AR-N 4300<\/b> were modified (copolymer from\u00a0 PMMA and polyhydroxystyrene instead of novolak) and the bottom resist <b>AR-P 5400<\/b> was varied additionally. The resist <b>SX AR-N 4340\/10<\/b> is clearly more thermoresistant than the positive resists. The figure displays the two-layer system after development and a thermal treatment at 200 \u00b0C. The negative resist shows no interference whatsoever by the tempering step.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-17553\" src=\"https:\/\/www.allresist.com\/wp-content\/uploads\/sites\/2\/2022\/06\/y.jpg\" alt=\"\" width=\"200\" height=\"150\" \/><\/p>\n<p>Fig. 2: Undercut after thermal treatment<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-2leug-72e9c06b3f20dbfb84e828d189b6f3e3\">\n.flex_column.av-2leug-72e9c06b3f20dbfb84e828d189b6f3e3{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-2leug-72e9c06b3f20dbfb84e828d189b6f3e3 av_one_third  avia-builder-el-8  el_after_av_two_third  avia-builder-el-last  flex_column_div av-zero-column-padding  '     ><p><section  class='av_textblock_section av-jv05s-db545b78e854cbd479b564510c904f86 '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Overview Photoresists- Negative<\/p>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-cn580-2e0537d1e2b6f4c4fd499829bacf94a4\">\n#top .hr.hr-invisible.av-cn580-2e0537d1e2b6f4c4fd499829bacf94a4{\nheight:25px;\n}\n<\/style>\n<div  class='hr av-cn580-2e0537d1e2b6f4c4fd499829bacf94a4 hr-invisible  avia-builder-el-10  el_after_av_textblock  el_before_av_magazine '><span class='hr-inner '><span class=\"hr-inner-style\"><\/span><\/span><\/div><br \/>\n<div  id=\"avia-magazine-1\"  class='av-magazine av-6s400-80d5d6f0e955eff30b21b08a54c0a3d8  avia-builder-el-11  el_after_av_hr  avia-builder-el-last   avia-builder-el-11  el_after_av_hr  avia-builder-el-last ' ><div class='av-magazine-group sort_all'><article class='av-magazine-entry av-magazine-entry-id-17422 av-magazine-format-standard av-magazine-type-post av-magazine-entry-1 av-magazine-entry-small av-magazine-no-thumb'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class=\"av-magazine-content-wrap\"><header class=\"entry-content-header\"><time class='av-magazine-time updated'  itemprop=\"datePublished\" datetime=\"2022-05-31T12:43:25+01:00\" >31.
