- 17:5917:59, 20 April 2021 diff hist +234 m Food microbiology Clarified the role of food testing labs in the food safety discussion Tags: Reverted Visual edit
- 17:2917:29, 20 April 2021 diff hist −724 Electroplating The description as written was technically wrong. ECD evolved for the reasons I stated: copper can't be etched, and an alternative technology to PVD and CVD needed to be developed for building conductive wires in advanced semiconductor chips. If you doubt me, look at the IBM website's history pages. Tags: references removed Visual edit
- 17:1317:13, 20 April 2021 diff hist +113 Thin film The text as written was wrong. Electroplating (in the form of electrochemical deposition) has been used to create copper conductive wiring in advanced semiconductor chips since the late 1990s, pioneered by IBM. It has nothing to do with CMP (chemical mechanical polishing). You need to use copper electroplating to produce copper conductive wires because you can't use a CVD (chemical vapor deposition process) as you can with aluminum wires: copper is too hard to etch Tag: Visual edit
