The Complete Deposition Platform

Every deposition method -
one foundry

Most devices need multiple deposition steps, sputtered metal contacts, PECVD dielectric insulation, ALD gate oxide, and MBE epitaxial growth can all be required in the same device. All of these are managed within a single project by a dedicated project manager.

PECVD, LPCVD & LTPS

CVD, plasma-enhanced · low-pressure · low-temperature polysilicon · DLC

CVD methods grow films from gas-phase precursors, enabling conformal coverage of complex 3D structures, trench sidewalls, via liners, and MEMS cavities, that PVD cannot reach. PECVD operates at low temperature, compatible with completed device structures and flexible substrates. LPCVD delivers high-quality polycrystalline silicon, silicon nitride, and deposited oxide films (thermal oxide is grown separately by oxidation).

Atomic Layer Deposition

ALD, Sub-nm Precision,
Near-ideal Conformality

ALD, self-limiting surface chemistry; growth per cycle depends on material and process
1 cycle
per cycle: material dependent

ALD uses sequential, self-limiting surface reactions. Growth per cycle depends on the material and process and is commonly a fraction of a monolayer, which gives three properties that are hard to reach with other methods: sub-nanometer thickness control, near-ideal step coverage into deep trenches and vias on qualified geometries, and dense, continuous films. These make ALD the method of choice for gate dielectrics, passivation layers on compound semiconductors, and moisture barrier coatings.

Al₂O₃, Aluminum Oxide

Most widely deposited ALD material. Gate dielectric for GaN HEMTs, passivation for GaAs/InP surfaces, moisture barrier for OLED displays and flexible electronics.

Essential for III-V photonic and power devices, and for research-grade quantum structures.

"100+ materials"

At Nanosystems JP Inc., we offer over 100 sputtering targets and the process knowledge to hit your target properties: resistivity, stress, refractive index, and crystallographic texture, on the first or second run, not the tenth.

01

Every deposition method

PVD, CVD, ALD, MBE, IBAD, thermal oxidation, and roll-to-roll, all available in one coordinated process flow. Your process flow doesn't need to split across separate process steps for different deposition methods.

02

Piezoelectric specialist

PZT, AlN, KNN, and LiNbO₃ deposition with orientation control, a capability that distinguishes us from general-purpose foundries. We serve MEMS transducer and BAW filter customers specifically.

03

Large panel capability

500×600mm rectangular substrates in the same sputtering system as standard wafers. Scale your process from 4-inch wafer R&D to glass-panel production without changing foundry.

04

Full patterning integration

Deposition is often followed immediately by photolithography, etching, and liftoff. All coordinated. We quote and manage the full sequence, not just the deposition step in isolation.

05

AuSn solder for photonics packaging

AuSn (80/20) UBM deposition by layered thermal evaporation, a specialist capability for silicon photonics flip-chip assembly that most MEMS foundries don't offer.

Thin film deposition on
optical-grade fused silica

Fused silica (SiO₂) is a preferred substrate for precision optical coatings and photonic thin film processes. Its broad UV-to-IR transmission window, ultra-low thermal expansion, and chemical stability make it well-suited for deposition processes where substrate outgassing, thermal distortion, or optical interference would compromise film performance.

AR & HR Coatings

Anti-reflection and high-reflection multilayer stacks deposited on fused silica using PVD (e-beam evaporation or ion-beam sputtering). Applied to optical windows, laser output couplers, and photomask blanks where wavelength-specific reflectance control is critical.

Conductive & Functional Films

ITO, metal, and dielectric films on fused silica for electrooptic devices, biosensors, and RF substrates. The low dielectric loss and high chemical purity of optical-grade fused silica minimizes substrate-induced interference in functional film characterization.
