To achieve resource-efficient production without the use of chemical etching agents or vacuum technology, manufacturers and suppliers of electronic components rely on plasma systems suitable for in-line integration. <\/p>\n<p>Due to their high electrical conductivity, copper and silver in particular are used in the semiconductor industry. Oxidation under normal ambient conditions can lead to problems with soldering and electrical conductivity. Whilst the problematic oxide and sulphide layers can be removed using conventional methods, these are often technically complex: energy-intensive thermal reduction processes or low-pressure treatments involving the associated vacuum technology.  <\/p>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2b8728d elementor-widget elementor-widget-aux_modern_heading\" data-id=\"2b8728d\" data-element_type=\"widget\" data-widget_type=\"aux_modern_heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<section class=\"aux-widget-modern-heading\">\n            <div class=\"aux-widget-inner\"><h2 class=\"aux-modern-heading-primary\">Plasma system used and working gas<\/h2><\/div>\n        <\/section>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-5352293 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"5352293\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"aux-parallax-section elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-8e9ac41\" data-id=\"8e9ac41\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-d673efa elementor-widget elementor-widget-text-editor\" data-id=\"d673efa\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Our research partner, <strong>INNOVENT e.V.<\/strong>, has carried out investigations using the<strong> TIGRES CAT system<\/strong> into the targeted reduction of sulphide and oxide layers on silver and copper surfaces.
