- iancmceachern 4y agoThe context of my comment was in response to the parent saying they've phased out/changed many of the worst stuff in the photo resist side and so I said there is still pretty bad stuff on the etch side and then you commented that there are worse chemicals on the photo resist side. We're in a weird circular argument. Point is - there are lots of bad chemicals used in semiconductor manufacturing, even today.
