Lift-Off Patterning

PVD sputtering and e-beam evaporation are the deposition methods used in lift-off patterning flows. We offer the full lift-off service - resist, exposure, PVD deposition, and solvent strip - for Au, Pt, TiN, and AuSn multi-layer stacks.

The Complete Deposition Platform
Every deposition method -
one foundry partner

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. We coordinate all of these within a single project, with no technology transfer between vendors.

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 the highest-quality polycrystalline silicon and thermal oxide films.

Atomic Layer Deposition

ALD, Sub-nm Precision,
Perfect Conformality

ALD, self-limiting surface chemistry, 1 monolayer per cycle
1 cycle
= 1 atomic monolayer

ALD uses alternating, self-limiting surface reactions to grow films exactly one atomic monolayer at a time. This gives three unique properties no other method can match: sub-nanometre thickness control, perfect step coverage into the deepest trenches and vias, and pinhole-free films. These make ALD the method of choice for gate dielectrics, passivation layers on compound semiconductors, and moisture barrier coatings.

Al₂O₃, Aluminium Oxide

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

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
