Infrared microscopy (Microscopy) is a method to look through a silicon wafer because silicon is transparent to infrared light.

Method of operation

Using infrared (IR) light and an IR detector, it is possible to see through a silicon wafer to see if patterns line up on the front and back of a wafer, allows wafer bonds to be checked, and determine if alignment has shifted during the bond aligning process. While the silicon is transparent, oxide is more absorptive thereby appearing darker, and metal will block the IR. With a


Here we describe what parameters are of importance in this technology (e.g. power, temperature...). May not be relevant to some technologies.

Parameter 1

Main article: Parameter 1

You may want to make a separate sub-page or article specifically for a parameter if this is longer than, say a paragraph or two. If not, get rid of the {{main|xyz}} below the heading.

Subtechnology 1

Main article: Subtechnology 1

Describe any sub-technologies of this technology.


How is this technology used in nanofabrication and what types of devices/research areas is it useful in?


Optional description of materials that can be processed by technology. I think the best example of where this comes in handy would be with LPCVD describing the difference between HTO and LTO.


If this is a "main category" for equipment (i.e. you categorized that equipment page to be this technology), you should list the equipment here with a brief description of that tool's capabilities. Seriously, though, just check out the RIE page.

Equipment 1

Main article: Equipment 1

Brief description of that piece of equipment.
