Abstract: The present invention provides a device structure and method of forming a finFet device having stacked fins. The method of the present invention comprises: providing a substrate with a first semiconductor layer on a first insulator layer, a second insulator layer on the first semiconductor layer, and a second semiconductor layer on the second insulator layer; forming a first fin and a second fin in the second semiconductor layer; masking the first fin; and forming a third fin in the first semiconductor layer, where the second fin is stacked on the third fin. The structure of the present invention comprises: a semiconductor substrate having a first semiconductor layer on a first insulator layer, a second insulator layer on the first semiconductor layer, and a second semiconductor layer on the second insulator layer; a first and second fin formed in the second semiconductor layer; and a third fin formed in the first semiconductor layer, where the second fin is stacked on the third fin.

Abstract: The present invention relates generally to a new ceramic structure and process thereof. Basically, the present invention relates to a structure and method for forming laminated structures and more particularly to a structure and method for fabricating multi-layer ceramic products using very thin green sheets and/or green sheets with very dense electrically conductive patterns on top of a stronger support sheet. The structure and method of the present invention enables the screening, stacking and handling of very thin green sheets and/or green sheets with very dense metallized patterns in the manufacture of multi-layer ceramic packages. The thin green sheets were tacked/bonded to thicker and stronger support sheets to form a sub-structure which had excellent stability in screening and enabled further processing. The sheets are anchored or pinned in such a way as to allow the processing of the green sheet with the subsequent easy removal of the support sheet.
