Are you able to process 200mm wafers in your facilities? 2018-01-16T00:07:17+00:00

Yes, we have the capability to work with 200 millimeter wafers.

Can I place multiple units on a metal sheet and cut them out? 2018-01-10T20:58:45+00:00

Photo Sciences can place multiple units on a sheet and remove them to provide individual units.

Can Photo Sciences manufacture deposition/shadow masks in stainless steel? 2018-01-16T00:08:33+00:00

At this time Photo Sciences does not have a stainless steel process. This is due to lack of demand.

Can you build glass in circular shapes? 2018-01-16T01:04:44+00:00

Yes. Our glass shaping team can core drill inner and outer diameters. We can also create inside cuts, angles and radiuses. For simple square or rectangle products we use our dicing saw technology.

Can you process .1mm glass? (as thin as paper) 2018-01-11T20:36:05+00:00

Currently, we do not have the equipment and tooling to work with .1 millimeter glass.

Do you accept other data formats than; DWG, GDS, DXF? 2018-01-16T00:06:01+00:00

We also accept raster and vector files. In addition, we can work from drawings, sketches and simple descriptions. Currently, we are working on the upload site to allow a larger variety of formats.

Do you have any tips/techniques for placing a shadow mask on top of the silicon substrate and clamping it down without a lot of scraping between the mask and substrate? 2018-04-12T23:43:35+00:00

Typically, a pin alignment fixture is used and often made by the customer, but Photo Sciences can facilitate the process.

Do you offer sputtered ITO? 2018-01-15T23:58:04+00:00

At this time, we do not have a process for sputtered ITO. This is due to lack of demand.

How long does it take to get my photomask? 2018-01-16T00:07:43+00:00

A 4 to 6-inch chrome mask will ship 48 hours after plots are approved and payment is received. 8-inch and iron oxide will ship in 72 hours.

I’m looking to fabricate some shadow masks to use in an electron-beam evaporator. I heard that the smallest opening you can achieve is 25µm. What about the spacing between the openings? Can they be made at 100µm? 2018-04-12T23:46:01+00:00

The standard feature size, or opening, is 20 microns. Tightened feature sizes can be 10 microns or better, depending on the data provided.

Is the shipping included in the mask price? 2018-01-16T00:06:43+00:00

Shipping is an additional cost which is determined by the customer.

What is a PCM? 2018-01-15T23:46:31+00:00

PCM means process control monitor. This is a test pattern that we place along the edge of every mask. It contains several designs that allow us to quickly verify that the equipment and process remains within the required parameters.

When will I get my quote? 2018-01-10T21:08:02+00:00

We will send you a formal quote within a couple of hours or within a couple of hours of the next business day.
