Patent number: 11740185Abstract: A method of detecting defects in a structure sample comprising a thin film layer and a sacrificial later is disclosed. The method comprises exposing the thin film layer to a vapour phase etchant, obtaining an image of the thin film layer and analysing the image. The vapour phase etchant enhances any defects present in the thin film layer by passing through the defect and etching a cavity within the sacrificial layer. The cavity undercuts the thin film layer resulting in a stress region surrounding the defect. Defects which were not originally detectable may be made detectable after exposure to the vapour phase etchant. A vapour phase etchant has the advantage of being highly mobile such that it can access defects that a liquid phase etchant might not. Furthermore, unlike a liquid phase etchant, a vapour phase etchant can be used to test a sample non-destructively.Type: GrantFiled: August 29, 2019Date of Patent: August 29, 2023Assignee: MEMSSTAR LIMITEDInventors: Anthony O'Hara, Daniel Drysdale
