Abstract:
1. A device comprising: an interposer comprising a through via extending through at least a portion of the interposer; a first metallization layer overlying the interposer and electrically connecting the through via; a second metallization layer overlying and electrically connecting the first metallization layer; a first insulating layer formed between the first metallization layer and the second metallization layer; an etch stop layer overlying the first insulating layer; a second insulating layer overlying the etch stop layer, the second metallization layer being partially within the first insulating layer between a lower surface of the etch stop layer and the first metallization layer, and partially within the second insulating layer; a capacitor formed in the first insulating layer positioned between the first metallization layer and the second metallization layer; a first via plug formed in the first insulating layer, wherein the capacitor electrically connects to the second metallization layer through the first via plug; and a second via plug formed in the first insulating layer, wherein the first metallization layer electrically connects to the second metallization layer through the second via plug.
