Abstract: In a vertical-transistor DRAM cell, the problem of making a reliable electrical connection between the node of the deep trench capacitor and the lower electrode of the vertical transistor is solved by; depositing a temporary insulator layer, forming a vertical spacer on the trench walls above the temporary insulator, then stripping the insulator to expose the substrate walls; diffusing dopant into the substrate walls to form a self-aligned extension of the buried strap; depositing the final gate insulator; and then forming the upper portion of the DRAM cell.

Abstract: PROBLEM TO BE SOLVED: To provide a structure for an integrated carrier equipped with high frequency and high speed passive components for computing. SOLUTION: A carrier 200 for a semiconductor component 102 is provided, which has passive components 3010 integrated in its substrate. The passive components 3010 include decoupling components, such as capacitors and resistors. A set of connections 210 is integrated in a close electrical proximity to the supported components.
