Title: Способ анизотропного плазменного травления кремниевых микроструктур в циклическом двухшаговом процессе окисление-травление
Inventor: AVERKIN SERGEJ NIKOLAEVICH
IPC: H01L21/3065
Filed: 2018-08-17
Granted: 2019-06-18
Abstract: Использование: изобретение относится к технологии изготовления транзисторов, интегральных схем, приборов силовой электроники и устройств микромеханики (МЭМС) на основе кремния. Способ анизотропного плазменного травления кремния представляет собой циклический двухшаговый процесс травление-пассивация, характеризующийся тем, что на шаге пассивации в качестве пассивирующей пленки на поверхностях формируемой микроструктуры используется слой SiO, создаваемый реакцией окисления кремния в плазме O. С целью предотвращения изменения состава пассивирующей пленки и для лучшего разделения во времени стадий травления и пассивации, а также предотвращения образования в объеме реактора смеси SFи O, в которой не происходит эффективная пассивация поверхности слоем оксида кремния, используются шаги откачки между шагами травления и пассивации длительностью от 0,5 до 10 с. Техническим результатом является обеспечение анизотропного травления кремния при температуре, близкой по значению к комнатной. Преимуществом данного способа является отсутствие необходимости охлаждения и термостабилизации пластины в технологической камере при криогенных температурах, а также отсутствие загрязнений формируемой микроструктуры фтор-полимерными пленками, что позволяет исключить необходимость использования дополнительных технологических операций для очистки сформированных кремниевых микроструктур от загрязнений полимерами. 2 з.п. ф-лы.
