Abstract:
A device including multiple depth STI regions with sidewall profiles, and method of production thereof Embodiments include a top region having a substantially vertical sidewall profile; and a bottom region having a width greater than or equal to the top region and a sidewall profile.

Claim (Index 10):
A method of forming a multiple depth shallow trench isolation (STI) regions comprising:\n forming a top region having a vertical sidewall profile; forming a bottom region having a width greater than or equal to the top region and a sidewall profile; forming a first well in a portion of a substrate, wherein the first well is electrically isolated from the substrate; forming a second well in a portion of the first well, wherein the second well is electrically isolated from the first well and the substrate; forming a stack over the second well; and forming the multiple depth STI regions, laterally separated, through the stack to the substrate, wherein at least one of the multiple depth STI regions is deeper than other multiple depth STI regions, wherein forming the top region of the multiple depth STI regions includes: forming a first, second and third multiple depth STI regions, laterally separated, through the stack to the second well; and expanding vertically the first and third multiple depth STI regions through the second well to the first well by a deep fence formation process, wherein the deep fence formation process comprises reactive-ion etching (RIE) or dry etching.
