Laser interference lithography for nanomanufacturing of scale gratings

Prof. Wei Gao
Tohoku University

Abstract

One-dimensional gratings, also called line gratings, have long been used in physics and astronomy for the study of spectra. They have also been applied to optical linear encoders for displacement measurement as a possible alternative to the laser interferometer. In recent years, the linear encoder has been expanded to the planar/surface encoder for multi-axis measurement where a two-dimensional (2D) diffraction grating is employed as the scale grating. Mask-based optical projection lithography is traditionally employed to manufacture the line scale gratings. However, the equipment used in the projection lithography as well as in the related EB mask fabrication is extremely expensive, and can only be operated in large companies. The minimum grating period of a commercial 2D planar scale grating is also limited to several micrometers, resulting in a relatively large signal period of encoder output. To reduce the fabrication cost and the period of a 2D scale grating, it is expected to employ the mask-less laser interference lithography (LIL), which is much more cost-effective in fabricating periodic microstructures with a short grating period down to half of the laser light wavelength. This keynote presents a new multi-beam two-axis Lloyd’s mirror interferometer that can solve the problems inherent in the conventional LIL technique for fabrication of 2D scale gratings. The proposed multi-beam setup is based on the division of wavefront, which has shorter optical path differences and thus is more robust compared with the existing multi-beam techniques based on the division of amplitude. The principle of the two-axis interferometer and some experimental results of fabricating scale gratings with a period of 1 mm or below are described.

Model-based manufacturing digital thread to transform
co-design with manufacturing

Dr. Changsheng Guo
Raytheon Technologies Research Center

Abstract

Design for Manufacturability (DFM) has become an engineering discipline with detailed processes and checklists developed for a wide range of specific product types. However, implementing DFM in practice has been challenging for complex parts such as jet engine compressor rotors and turbine components, where advanced designs with more complex geometry, advanced materials, and tighter tolerance requirements impose even greater manufacturing challenges. DFM becomes critically important for the development of these complex parts. The growing adoption of industry 4.0 and availability of detailed manufacturing data are creating a real opportunity for transforming the product development and implementing co-designing with manufacturing. There is also an urgent need to establish industry-standard to facilitate efficient data exchanges. This presentation will discuss how the industry can use model-based digital thread from design to manufacturing to capture and link all production data to the part design features, how to use the digital thread to automatically extract manufacturing knowledge and manufacturing capabilities at part feature level and use the extracted knowledge to develop better products.

Inkjet printing manufacturing technology for flexible displays

Abstract

Flexible displays attract much attention in recent years due to their endless possibilities for wearable integrated systems and portable devices. However, how to break the limit of manufacturing resolution, efficiency, and reliability, together with device deformation capacity is still of great challenge. Here, we introduce our recent works aiming at solving the above problems based on the high-resolution electrohydrodynamic (EHD) printing technique. First, the generation, development, and disappearance of the femtolitre-sized droplet during EHD printing processes are discussed to reveal the manufacturing mechanism. Then, the key technologies including the array design of EHD printing heads, dynamic 3D measurement of flying/deposited droplets, multi-nozzle printing planning, and online automated optical inspection are introduced. Finally, all these technologies eventually evolved into a series of equipment, and they show great flexibility and high performance in the field of flexible displays manufacturing.

Precision measurement of complex optics by use of a scanning point multi-wavelength interferometer operating in visible domain

Dr. Marc Wendel
Ametek GmbH / BU Taylor Hobson

Abstract

The growing demands of optical systems lead to increasingly complex aspheres and free-forms. An established measurement system in asphere production, which is a promising approach in high precision freeform metrology as well, is presented. It is based on a scanning point multi-wavelength interferometer approach. The scanning principle enables great flexibility, reduces setup time and costs, and has almost no limitations in spherical departure. Due to the absolute measurement capability, the utilized multi-wavelength approach is beneficial for segmented, annular, and discrete surfaces, which are common designs of modern applications’ optical elements. The metrology system enables measurements in nanometer-scale on a great variety of apertures – from 1 mm to 1000 mm. Recently, a new short-coherence multi-wavelength interferometer, operating in the visible domain, has been developed. This enables the high precision measurement also on Si coated surfaces, which are commonly used for E-UV lithographic applications, for example. Here, also grating structures to suppress IR light in the E-UV process can be easily measured, thanks to the large absolute measurement capability. This contribution will summarize the basic working principle, highlight the capabilities of the visible multi-wavelength approach, and show the first measurement results.
