for Semiconductor Manufacturing
Micron precision, born of ceramics.
Backed by the Shanghai Institute of Ceramics and Ningbo Institute of Materials, Chinese Academy of Sciences, we engineer precision parts in alumina, silicon carbide and aluminum nitride for the global semiconductor equipment industry.
Since 2009, we have devoted ourselves to one craft —
turning advanced ceramic science into parts that serve,
micron by micron, inside the plasma chamber.
Our R&D team — 3 PhDs, 5 masters and 15 senior engineers — delivers custom precision machining, thermal spray and CVD coating to customer drawings.
From formulation to final metrology, every part closes its loop inside one quality system — the root of our delivery consistency.
Nine ultra-hard ceramics,
controlled from powder to part。
Covering the principal ceramic systems of semiconductor manufacturing — formulation, sintering and finishing all under one roof.
Three sites,
one system。
From forming and sintering in Pingxiang, to cleanroom finishing in Ningbo, to metrology across the line — a complete manufacturing chain for semiconductor parts.
Pingxiang · Forming & Sintering
Over ten production units — sintering furnaces, degassing machines — for formulation, forming and high-temperature sintering.
Ningbo · Cleanroom Finishing
Including a 4,000 ㎡ cleanroom and an 80 ㎡ Class-100 area, meeting semiconductor-grade cleanliness.
Machining & Metrology
Machining centers, ID/OD and surface grinders, CMMs, surface roughness testers — over fifty precision units.
Compatible with 24 Major Tool Platforms
OEM IndexPrecision is our mother tongue。
Ultra Flatness
Under 0.5 μm across a Φ590 mm workpiece — qualified for DMP and CMP processes.
Optical-grade Polishing
Ion-beam figuring achieves PV below 0.1 μm over a Φ600 mm aperture.
Ceramic Micro-drilling
Micro-holes down to 0.1 mm × 1.2 mm — for the dense hole arrays of shower heads.

LEDFrequently asked questions。
Are you the OEM? What is your relationship to AMAT / NAURA / LAM / SPTS?
Shanghai Bilateral Electronics is an independent manufacturer of semiconductor ceramic components, producing OEM-equivalent replacement parts built to the same material and grade. All brand names and part numbers are trademarks of their respective owners, used for identification only; we are not affiliated with, authorized by, or endorsed by the original equipment manufacturers.
Do you provide a Certificate of Conformance (COC)?
Yes. Every lot ships with a Certificate of Conformance (COC) verifying that material and grade meet specification.
Can you make parts to an OEM part number or to my drawing?
Yes. Provide an OEM part number for a cross-referenced equivalent, or we custom-develop from your drawing or sample, with precision machining to ±0.01 mm.
What materials do you work with?
Alumina (Al₂O₃), silicon carbide (SiC), aluminum nitride (AlN), silicon nitride (Si₃N₄), quartz and other ultra-hard ceramics — formulation, sintering and finishing all in-house.
Which equipment platforms do you support?
AMAT, NAURA, LAM, SPTS and more — compatible with 24 major semiconductor tool platforms, serving deposition, etch, ion-implant and other core processes.
How do I get a quote? What about lead time and MOQ?
Send a part number or drawing to sales@bilateral.top or use the inquiry form; our engineers respond within 24 hours. Prototyping and volume are both supported; lead time and MOQ depend on the specific part and quantity.
