Before ARC® materials were introduced in 1981, IC manufacturers faced increasing challenges posed by reflections from the underlying substrate during the exposure step. The highly reflective substrate (typically a polished silicon wafer) would cause light from the exposure to bounce back into the photoresist, resulting in phenomena such as standing waves and reflective notching. These defects could ruin the fidelity of the pattern in the photoresist. Brewer Science introduced ARC® antireflective coatings to mitigate these reflections and allow for the continued reduction of IC feature sizes for decades to come. Without the introduction of ARC® materials, the nanoscale circuitry that drives modern electronic devices would not be possible.

ARC® antireflective coatings are the industry benchmark for reflection control and light absorption during photolithography.

Also, deep blocking is cumbersome and slow to verify in a photo spectrometer. At Delta Optical Thin Film, we always enter into a thorough discussion with our customers to prevent unnecessary cost.

Another important aspect of a Bandpass Filter is the rejection or blocking range and level. These parameters specify in which wavelength ranges the filter must reflect as well as the permitted transmittance at these wavelengths.

As the original bottom antireflective coatings (BARCs), ARC® antireflective coatings continue to be the industry benchmark for reflection control and light absorption during photolithography. Our proven line of anti-reflective coatings spans all the way from legacy 365-nm (i-line) processes to cutting-edge 193-nm immersion processes. ARC® materials are known for their customizable process window, broad photoresist compatibility, and benchmark pattern fidelity.

Modern filters often provide OD6 or better rejection in a very wide wavelength range. However, overspecifying blocking level and range will often lead to an increase in the  number of layers in the filter causing increased production cost.

Brewer Science offers the most diverse catalog of 193-nm BARCs in the industry, with over 50 materials available commercially. Our 193-nm BARCs are designed with photoresist compatibility and process flexibility in mind, and many offer tunable optical properties allowing for further process customization.

Delta Optical Thin Film are pioneers and innovators in the design and manufacture of robust optical thin film components for a broad range of volume applications. We have designed and manufactured optical interference bandpass filters since the early 1970’ties.

Although cutting-edge lithography has moved to shorter wavelengths, i-line (365-nm) and deep ultraviolet (DUV, or 248-nm) lithography continue to be industry workhorses for many critical steps of the IC manufacturing process. In addition, many devices that are part of the Internet of Things are created using these legacy processes. Brewer Science maintains a full catalog of DUV and i-line antireflective coatings to meet all of these needs.

Optical Bandpass Filters are spectrally selective components capable of transmitting specific wavelengths of light while blocking others. These filters are fully customizable in terms of center wavelengths and bandwidths, making them suitable for a wide range of applications, including fluorescence spectroscopy, microscopy, and flow cytometry. Optical Bandpass Filters provide consistent optical filter functions across the entire clear aperture. In contrast, Continuously Variable Filters offer a filter function that varies along one dimension of the filter.

The function of a Bandpass Filter (BP filter) is described by the center wavelength of its transmission band and the with of the band. E.g. a Bandpass Filter can be described as BP578/50, which is a filter with a center wavelength of 578 nm and a bandwith of 50 nm. Within the passband, it is typical to define the minimal or average transmission level. In modern coatings, despite several hundreds of layers, minimum transmission levels of 90% is not uncommon.
