摘要: According to an example embodiment, a semiconductor device having a back side and a circuit side opposite the back side is analyzed. The semiconductor device includes bulk silicon in the back side and also includes epitaxial silicon. An ion gas comprising SF6 and N2 is directed at a target region in the back side. Using the ion gas, the target region in the back side is selectively etched using reactive ion etching (RIE) and an exposed region is formed. The etching is selective to the bulk silicon. When the etching process encounters the epitaxial silicon, the etch rate slows and is used as an endpoint indicator of the selective etching process. Once the etching process is stopped, the circuitry is accessed via the exposed region.

摘要: Current reactive ion etching (RIE) techniques are not applicable to back side etching of semiconductor devices. According to an example embodiment, the present invention is directed to a method for analyzing a semiconductor device having a back side and a circuit side opposite the back side. An ion gas including SF6 and N2 is directed at a target region in the back side. Using the ion gas, the target region is etched using reactive ion etching (RIE). An exposed region is formed, and circuitry in the device is accessed via the exposed region. The use of the ion gas enables back side RIE that is capable of producing an etched surface that is usable for back side access.
