Record Low Resistivity Titanium Nitride Film Fabricated by Thermal ALD – Ultra-dry hydrazine enables growth at low temperature

PUBLISHED JANUARY 18, 2022

Low resistivity is an indicator of a high-quality film that works well as a barrier layer or conductor. TiN thin films are used as diffusion barriers for cobalt (Co) and tungsten (W) metal layers as well as gate metal in CMOS devices due to their high electrical
conductivity and related low resistivity.

The Emergence of Hydrazine (N2H4) in Semiconductor Applications

PUBLISHED JANUARY, 2022

Historically, metal-nitride MOCVD and ALD ALD films have used Ammonia (NH3) for fabrication of advanced semiconductor devices. However, lower thermal budgets and shrinking 3-dimensional structures needed in next generation devices have exposed limitations with ammonia usage in semiconductor processing. However, these studies are far from comprehensive due to the vast number of possible metal nitrides along with a countless number of potentially useful metal precursor materials.

Technical White Paper – ALD Nitride Wizard

PUBLISHED JANUARY, 2022

In recent years production worthy, ultra-dry gas-phase Brute© hydrazine (N2H4) has been developed and made available by Rasirc. Prior to this work, attempts to deliver hydrazine gas were technically challenged due to moisture and safety issues which caused many studies to produce inconsistent results with oxygen incorporation into films.1-3 Therefore, little was actually known about low moisture gas phase N2H4reactivity in ALD and other potential nitridation applications.

BRUTE Peroxide Datasheet

PUBLISHED IN 2017

RASIRC BRUTE Peroxide provides a breakthrough method to deliver virtually water-free hydrogen peroxide (H2O2) gas into Atomic Layer Deposition (ALD) and Etch (ALE) processes. BRUTE Peroxide solution is preloaded in a RASIRC vaporizer. This solution combines hydrogen peroxide liquid and a proprietary solvent, which ensures that the liquid source remains below 30% by weight hydrogen peroxide.

Anhydrous Hydrogen Peroxide Gas Delivery for Atomic Layer Deposition

PUBLISHED IN 2016

In order to minimize defects, enhance uniformity and increase device performance, researchers have begun to focus on the interface between dielectric materials and Si, SiGe, Ge and InGaAs. Most defects, which lead to charge traps and decreased mobility, are believed to occur in this interfacial region. While cartoons of ALD show nice monolayer continuous growth, ALD growth usually occurs in islands on the surface with 3 cycles typically needed for each monolayer. More surprising is that initiation of ALD growth on the surface is far from ideal. Initial film growth of the first monolayer may take up to 6-7 cycles. Research suggests that significant device improvements can be made if the surface is functionalized with a dense layer of hydroxyl groups –OH, prior to deposition.
