Methods for growing low-resistivity tungsten for high aspect ratio and small features

The present invention addresses this need by providing methods for depositing low resistivity tungsten films in small features and features having high aspect ratios. The methods involve depositing very thin tungsten nucleation layers by pulsed nucleation layer (PNL) processes and then using chemical vapor deposition (CVD) to deposit a tungsten layer to fill the feature. Depositing the tungsten nucleation layer involves exposing the substrate to alternating pulses of a boron-containing reducing agent and a tungsten-containing precursor without using any hydrogen gas, e.g., as a carrier or background gas. Using this process, a conformal tungsten nucleation layer can be deposited to a thickness as small as about 10 Angstroms. The feature may then be wholly or partially filled with tungsten by a hydrogen reduction chemical vapor deposition process. Resistivities of about 14 μΩ-cm for a 500 Angstrom film may be obtained.

Nitrided sti liner oxide for reduced corner device impact on vertical device performance

A method of fabricating an integrated circuit device comprises etching a trench in a substrate and forming a dynamic random access memory (DRAM) cell having a storage capacitor at a lower end and an overlying vertical metal oxide semiconductor field effect transistor (MOSFET) comprising a gate conductor and a boron-doped channel. The method includes forming trenches adjacent the DRAM cell and a silicon-oxy-nitride isolation liner on either side of the DRAM cell, adjacent the gate conductor. Isolation regions are then formed in the trenches on either side of the DRAM cell. Thereafter, the DRAM cell, including the boron-containing channel region adjacent the gate conductor, is subjected to elevated temperatures by thermal processing, for example, forming a support device on the substrate adjacent the isolation regions. The nitride-containing isolation liner reduces segregation of the boron in the channel region, as compared to an essentially nitrogen-free oxide-containing isolation liner.

Method of epitaxial-like wafer bonding at low temperature and bonded structure

A process for bonding oxide-free silicon substrate pairs and other substrates at low temperature. This process involves modifying the surface of the silicon wafers to create defect regions, for example by plasma-treating the surface to be bonded with a or boron-containing plasmas such as a B2H6 plasma. The surface defect regions may also be created by ion implantation, preferably using boron. The surfaces may also be amorphized. The treated surfaces are placed together, thus forming an attached pair at room temperature in ambient air. The bonding energy reaches approximately 400 mJ / m2 at room temperature, 900 mJ / m2 at 150° C., and 1800 mJ / m2 at 250° C. The bulk silicon fracture energy of 2500 mJ / m2 was achieved after annealing at 350-400° C. The release of hydrogen from B-H complexes and the subsequent absorption of the hydrogen by the plasma induced modified layers on the bonding surfaces at low temperature is most likely responsible for the enhanced bonding energy.
