Enabling next generation semiconductor processes.
Particle-free water vapor for oxidation applications. Get precision control without water droplets using DI water.
Ultra-Pure Hydrogen Peroxide
Water-free or humidified hydrogen peroxide gas. Hydrogen peroxide gas is ideal for surface functionalization, passivation, area selective deposition, multi-patterning ALD, gap fill and more.
Pure, dry, and safer hydrazine gas. Great for low temperature nitride ALD. Enables low resistivity without oxygen contamination.
RASIRC enables new process innovation with specialty gas generation
RASIRC products convert low vapor-pressure liquid chemistries into safer, reliable gases. These highly reactive chemistries generate thin oxide and nitride films at reduced temperatures for complex 3D structures in advanced microprocessors, memory, and III-V nitride devices.
BRUTE Hydrazine converts liquid hydrazine into pure, dry, and safer hydrazine gas. BRUTE Hydrazine is highly effective source for growth in low temperature nitride ALD and MOCVD. Films include titanium nitride, silicon nitride and aluminum nitride. BRUTE Hydrazine generates ultra-thin films with low resistivity and minimal oxygen contamination.
BRUTE Peroxide can be used for surface functionalization, surface passivation and area selective deposition. BRUTE Peroxide delivers a dense hydroxylated surface without oxidizing the sub-surface. Think Brute Peroxide instead of water, ozone, or oxygen plasma.
The Peroxidizer converts liquid hydrogen peroxide into hydrogen peroxide gas. This gas has a myriad of applications for next generation devices. The Peroxidizer can be used for gapfill cure, anneal, PR/ARC pre-treatment and more. The Peroxidizer generates high flows of H2O2 gas at low temperature for HVM applications.
RainMaker® Humidification System (RHS)
The RainMaker Humidification System (RHS) converts water into particle-free water vapor. This water vapor can then be used for oxidation or annealing. The RainMaker Humidification System (RHS) can be used in a wide variety of oxidation applications where up time and repeatability are critical.
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.
AVS ALD 2021- See multiple presentations from UCSD, UTD, and TNSC on H2O2 and Hydrazine
JUNE 27-30, 2021
RASIRC is contributing at the AVS ALD2021 Virtual conference. The results summarize the latest development using either hydrogen peroxide (H2O2) or hydrazine (N2H4) as powerful co-reactants in atomic layer processing of high-quality films with higher overall performance beyond that of classical thermal or plasma ALD processes.
