According to one embodiment, there is provided a semiconductor device, which includes an electrode lead-out part, a planarization film, contacts, and first and second columnar patterns. The electrode lead-out part is arranged such that an electrode film and an insulating film are alternately stacked in a plurality of layers, and layers of the electrode film are arranged stepwise. The planarization film is arranged above the electrode lead-out part. The first columnar pattern extends from a lowermost portion of the electrode lead-out part to a position lower than the upper side of the planarization film by a first depth. The second columnar pattern extends from a lowermost portion of the electrode lead-out part to a position lower than the upper side of the planarization film by a second depth larger than the first depth.

An SiO.sub.2 insulating layer is formed on an Si substrate, and an Si.sub.3 N.sub.4 insulating layer is formed on the SiO.sub.2 layer. A notch is formed in the Si.sub.3 N.sub.4 layer using a resist film as a mask. The SiO.sub.2 layer is etched using the Si.sub.3 N.sub.4 layer as a mask, thereby forming an opening larger than the notch cut in the SiO.sub.2 layer. As a result, the Si.sub.3 N.sub.4 layer extends over the opening in an overhanging manner. When As.sup.+ ions are implanted in the periphery of the notch of the Si.sub.3 N.sub.4 layer, the ion-implanted portion of the Si.sub.3 N.sub.4 layer is arcuated toward the base region. When a metal such as Ti is deposited on the arcuated portion, the metal is also deposited on the arcuated portion and the portion of the emitter region matching with the notch, thereby forming an emitter electrode portion.

摘要:
A method of etching away a selected portion of silicon oxide from a body of silicon oxide and tapering the edge of the remaining silicon oxide that delineates the selected portion comprises the steps of (a) delineating the selected portion with a coating of a photoresist on a surface of the body, and (b) etching away the selected portion with a composite solution that contains both an etchant for the silicon oxide and a component for lifting only the edge of the photoresist from the interface between the photoresist and the silicon oxide at the delineation of the selected portion.
摘要:
A method of forming multi-level metallization in integrated circuits with essentially zero effective lateral spacing between adjacent isolated metal portions. Indentations are formed at least partially through a first dielectric layer; and a second dielectric layer having apertures registered with and smaller than the indentations is formed thereover such that portions of the second layer overhang the indentations at the perimeters thereof. A thin metal layer then is deposited over the surface of the structure. Because the second dielectric layer overhangs the indentations, the deposited metal is discontinuous at the perimeter of each of the indentations if the deposited metal layer is kept sufficiently thin. Selective connection of adjacent metal portions at any portion of the perimeter of any indentation is made by any of a variety of techniques, such as electroless plating of gold through a photoresist mask.

A method for forming a semiconductor device comprises forming a gate stack on a channel region of a semiconductor, forming a source/drain region adjacent to the channel region, depositing a first insulator layer over the source/drain region, and removing a portion of the first insulator layer to form a first cavity that exposes a portion of the source/drain region. A first conductive material is deposited in the first cavity, and a conductive extension is formed from the first conductive material over the first insulator layer. A protective layer is deposited over the extension and a second insulator layer is deposited over the protective layer. A portion of the second insulator layer is removed to form a second cavity that exposes the protective layer, and an exposed portion of the protective layer is removed to expose a portion of the extension. A second conductive material is deposited in the second cavity.
