If the resist is processed according to the general protocol for positive resists without any additional steps, it works like a normal positive tone resist.<\/p>\n<p class=\"p2\">With the additional process steps \u201creversal bake\u201d after image-wise exposure and subsequent \u201cflood exposure\u201d, the material provides a negative resist image which is characterised by a particularly high contrast of patterns. As guideline value for the reversal bake, 30 min at 100 \u00b0C in a convection oven or 5 min on a hot plate at 115 \u00b0C is recommended. The subsequent flood exposure (2- to 3-fold exposure dose of the initial exposure) converts the unexposed areas into a developable form. For optimal patterning, the process steps image-wise exposure, flood exposure, and development have to be coordinated thoroughly.<\/p>\n<\/div><\/section><\/div>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-9qby-7de582faa85d6533a05a6965d235d59d\">\n.flex_column.av-9qby-7de582faa85d6533a05a6965d235d59d{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 0px;\n}\n<\/style>\n<div  class='flex_column av-9qby-7de582faa85d6533a05a6965d235d59d 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-25yfe-a0fe3b4c3a0fa6dbfbda3ba7b535769a '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p>Overview Photoresist FAQs<\/p>\n<\/div><\/section><br \/>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-1lrni-c046c01aff572535c32de7c78a0f953a\">\n#top .hr.hr-invisible.av-1lrni-c046c01aff572535c32de7c78a0f953a{\nheight:25px;\n}\n<\/style>\n<div  class='hr av-1lrni-c046c01aff572535c32de7c78a0f953a 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-ug0e-96c8868d595eeaf683af69fdbe394b18  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-17 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=\"2008-08-21T12:38:35+01:00\" >21.
