Custom Quartz Fabrication For Semiconductors

Diffusion and Single Wafer Process Parts




Since 1997, Jelight Company has been manufacturing high quality custom quartz parts for the semiconductor, fiber optic, and lighting industries.  Located in Southern California, Jelight Company houses a complete fabrication facility and continuously invests in its quartz capabilities.  We are an authorized distributor-fabricator of Momentive Performance Materials Quartz Inc. and approved supplier to many OEMs and end-users nationwide and all over the world. Here’s why you should choose Jelight Company over other custom quartz fabricator companies:


 Jelight Company has heavily invested in its fabrication, machining, and inspection equipment. This enables us to maintain strict tolerances and produce the highest quality products.  Our Quality Assurance inspection facility has the finest measuring equipment available, including a Brown & Sharp CMM.  All parts are manufactured according to the tolerance specifications required by today’s automation.  Jelight Company’s unique design of quartz ring burners and torches maintain the purity levels of quartz, greatly reducing the possibility of metal contamination during fabrication. Our vertically integrated in-house abilities include core drilling, grinding, and machining our own solid quartz from ingots. Additionally, our 24” bore lathe is capable of handling quartz tubing up to 600mm in diameter. 

As a testament to the dedication and skill at Jelight Company, we would like to introduce the largest (to our knowledge) process or furnace tube ever made in the USA. This tube is Ø22.83” [Ø 580mm] O.D X 25’ (ft.) [7.6 meters] in Length.


We offer an expansive parts list (shown below), and we can assist you with any custom parts. Jelight Company’s knowledgeable engineering team also provides our industry partners with R&Dreverse engineering support, and repair services.  The most commonly repaired quartz parts are 200 and 300 mm insulators, pedestals, and bell jars.
