摘要: The present disclosure relates to a method for forming a multi-dimensional integrated chip structure. In some embodiments, the method may be performed by bonding a second substrate to an upper surface of a first substrate. A first edge trimming cut is performed along a first loop and extends into a first peripheral portion of the second substrate. A second edge trimming cut is performed along a second loop and extends into a second peripheral portion of the second substrate and into the first substrate. A third edge trimming cut is performed along a third loop and extends into a third peripheral portion of the first substrate.

摘要: Some embodiments of the present disclosure relate to a method in which a functional layer is formed over an upper semiconductor surface of a semiconductor substrate, and a capping layer is formed over the functional layer. A first etchant is used to form a recess through the capping layer and through the functional layer. The recess has a first depth and exposes a portion of the semiconductor substrate there through. A protective layer is formed along a lower surface and inner sidewalls of the recess. A second etchant is used to remove the protective layer from the lower surface of the recess and to extend the recess below the upper semiconductor surface to a second depth to form a deep trench. To prevent etching of the functional layer, the protective layer remains in place along the inner sidewalls of the recess while the second etchant is used.

摘要: The present disclosure relates to an image sensor integrated chip having a deep trench isolation (DTI) structure having a reflective element. In some embodiments, the image sensor integrated chip includes an image sensing element arranged within a substrate. A plurality of protrusions are arranged along a first side of the substrate over the image sensing element and one or more absorption enhancement layers are arranged over and between the plurality of protrusions. A plurality of DTI structures are arranged within trenches disposed on opposing sides of the image sensing element and extend from the first side of the substrate to within the substrate. The plurality of DTI structures respectively include a reflective element having one or more reflective regions configured to reflect electromagnetic radiation. By reflecting electromagnetic radiation using the reflective elements, cross-talk between adjacent pixel regions is reduced, thereby improving performance of the image sensor integrated chip.

摘要: In a method for fabricating a semiconductor device, a trench is etched in a semiconductor substrate having a top surface, and a lining oxide layer is formed conformal to the trench. A negatively-charged liner covering the lining oxide layer and conformal to the trench is formed. The trench is partially filled with a flowable oxide to a level below the top surface of the semiconductor substrate, and the flowable oxide in the trench is cured. The negatively-charged liner above the cured flowable oxide is optionally removed. A silicon oxide is deposited in the remaining portion of the trench, and a planarization process is performed to remove excess portions of the silicon oxide over the top surface of the semiconductor substrate.

摘要: In some embodiments, the present disclosure relates to a method of forming an integrated chip. The method is performed by forming a gate dielectric layer over a substrate, and selectively forming a gate material over the gate dielectric layer. A gate dielectric protection layer is formed over the gate dielectric layer, and a first sidewall spacer is formed over the gate dielectric protection layer and flanking a side of the gate material. The gate dielectric protection layer continuously extends from between the first sidewall spacer and the gate dielectric layer to outside of the first sidewall spacer.
