Abstract

"MéTODO MELHORADO PARA TRATAMENTO DE MICRODESBASTE DE CIRCUITO DE COBRE E DE METAL MISTO". Processo para melhoria da adesão de materiais dielétricos a uma camada de metal, incluindo a provisão de uma camada de metal não-padronizada tendo uma primeira superfície principal, o microdesbaste da primeira superfície principal para a formação de uma superfície microdesbastada; e o ataque químico da camada de metal para a formação de um padrão de circuito na camada de metal, no qual o microdesbaste é realizado antes do ataque químico.
