Nano-imprint templates can be used in the development of many devices, such as semiconductors, storage devices, optical parts, biochips, and various MEMS devices. One benefit of using nano-imprint technologies, across the board, is its simplicity. It does away with the need for high powered excimer lasers or large, unwieldy stacks of precision ground lens elements in order to achieve the same kinds of nano resolutions. It has allowed chip manufacturers to therefore reduce costs.
Nano-imprint technology is certainly not new, but holds as yet unexplored possibilities for industry. At its simplest, it is a process of creating nanometer scale patterns by mechanically deforming, or imprinting, the imprint resist or template. The imprint resist is usually a polymer of some form that is cured by heat or UV during the imprinting. There are great advantages and some challenges to using nano-imprint templates and technologies in general.
Advantages of Nano-Imprint Technologies
Some of the advantages and features of using these nano-imprint templates include high transmissivity to deep UV, and UV resistance. Nano-imprint technologies feature low thermal expansion, but high heat resistance. They are accurate in multiple dimensions, and their flatness specifications are in sub-micron ranges. All of these features make nano imprint development a high priority for industry, allowing the possibility of smaller and smaller semiconductors, and smaller, electronic devices. The size of electronics has been an historically limiting feature, and the possibilities for
The Role of Optical Isolators
Optical Isolators, or optical diodes, are optical components that allow light to be transmitted in only one direction. They are typically used to prevent feedback into a laser cavity. The precise control of light allowed by the optical isolators is an essential the success of nano-technologies. Optical isolators, or optical patterning tools are more useful, the better their resolution is.
Synthetic Quartz Wafers
Synthetic Quartz Wafers also allow for the development of nano-technologies, or allow for improvements in them. Synthetic quartz wafers are unique in that they have very good light transmission properties. They are intended for use in applications that require high purity, and high precision polishing. Compared to glass, they have more flexibility. Synthetic quartz wafers has a low thermal expansion, especially when compared to ordinary glass. Also, they are better for optics, as they exhibit a high permeability over the wavelength range, in other words, from the ultraviolet region to the infrared region.
