[labnetwork] Photomask Manufacturing Companies

[Oles Fylypiv]

Dear Jayer,

Our lab has been purchasing masks from Advance Reproductions Corp, and we are pleased with them. Their website is:

http://www.advancerepro.com/.

The emails to their customer service representatives are:

d.robinson at advancerepro.com and m.nadeem at advancerepro.com.

The phone number is:

(978) 685-2991

They are located in Andover, Massachusetts.

A 4 X 4 X 0.090 soda lime coated with chrome cost us $450. This is pricey compared to writing one yourself on the DWL with a blank mask plate, yet it is worth it for us because the improved results are evident in our devices.


  *
The specs they can achieve are 0.75 um for the smallest dimension
  *
The critical dimension tolerance is +/-0.15 um.
  *   Glass sizes range from 3″ to 32″
  *
Substrate materials: quartz, fused silica, soda lime, borosilicate.
  *   Glass coatings: chrome, iron oxide, aluminum, titanium, gold, and emulsion
  *   Plate thickness: .020″ to .400″ (10mm)

I hope this helps you and the rest of the labnetwork community.

Very Respectfully,
Oles

Jim at Photomask Portal has done exceptional work for us for many years. I couldn't recommend him enough after many other vendors have let us down.

Hi,

I'm curious to know what service/company folks are using to make standard photomasks?
