Glass micromachining is becoming an essential material for optical micro-electro-mechanical-systems (MOEMS), miniaturized total analysis systems (µTAS), and microfluidic devices (e.g., for biosensing). In particular, the machining of smooth, high aspect ratio through glass vias (TGVs) in glass is crucial for the fabrication of interposers in the emerging packaging industry for small consumer electronics. However, glass is challenging to machine, in particular, at the micro-scale. Due to its brittleness, mechanical processes often result in undesired micro-cracks, and its relatively high thermal conductivity challenges the thermal process, which faces the issue of thermally affected zones. Additionally, its amorphous structure makes it difficult to etch high aspect-ratio structures. These challenges stimulate research in industry and academia, and, in recent years, this field has seen major advances.
This special issue seeks reviews, regular research papers and short communication on: (i) new approaches to micro machine glass, (ii) innovative use of existing techniques to address current challenges in glass micro-machining and (iii) opinions on future needs in glass micro-machining in emerging markets.

Title: Micro-hole drilling on glass substrates—A review
Authors: Lucas A. Hof and Jana D. Abou Ziki
Abstract: Glass micromachining is nowadays becoming essential for the fabrication of micro-devices including optical micro-electro-mechanical-systems (MOEMS), miniaturized total analysis systems (µTAS) and microfluidic devices for biosensing. Moreover, glass is RF transparent, making it an excellent material for sensor and energy transmission devices. Advancements are constantly being made in this field, yet machining smooth high-aspect-ratio through glass vias (TGVs) remains challenging due to glass poor machinability. As TGVs are demanded for several micro-devices, research is being immensely carried out on numerous number of glass micro-machining technologies. This paper reviews established and emerging technologies for glass micro-hole drilling describing their principles of operation and characteristics, and their advantages and disadvantages. These technologies are sorted under four machining categories: thermal, chemical, mechanical, and hybrid machining which combines several machining methods. Achieved features by these methods are summarized in a table and presented in two graphs.

Title: Plasma milled glass as templates for microfluidic applications
Author: Jesse Greener
Abstract: As microfluidics matures, new demands on production volumes and device complexities will put pressures on manufacturers to search for innovations in microfabrication techniques. In this paper, we evaluate the possibility of using templates based on a new plasma milling technique for polymer devices via curing of elastomers and hot embossing of thermoplastics. Target materials are PDMS. We evaluate this new approach in terms of the quality of template tools and imprinted parts, the ease of use and longevity of templates and the ability to generate 3D features.
