Part of the Malware glossary: An IFrame (Inline Frame) is an HTML document embedded inside another HTML document on a website. The IFrame HTML element is often used to insert content from another source, such as an advertisement, into a Web page. Although an IFrame behaves like an inline image, it can be configured with its own scrollbar independent of the surrounding page's scrollbar.
Reactive ion etching (RIE) is a directional etching process utilizing ion bombardment to remove material. The most notable difference between reactive ion etching and isotropic plasma etching is the etch direction. While RIE provides a much stronger etch, it also provides a directional etch. The plasma will etch in a downward direction with almost no sideways etching.
