In this paper, we present a laser etching and drilling technique for thin glass materials based on the use of finite-energy pulsed Bessel beams orthogonally impinging on the sample surface. Thanks to the elongated focal zone of the quasi-non-diffractive beam, the laser processing can be performed without scanning the beam position along the …
In this chapter, we will introduce major micro/nanofabrication techniques currently used to fabricate structures ranging from nanometers to several hundred microns in size. We will mainly focus on the most important and widely used techniques and will not discuss specialized methods. After a brief introduction to basic microfabrication, we will ...

A new strategy referred to as hybrid femtosecond laser microprocessing is also introduced, in which FLAE is combined with two-photon polymerization (TPP) to ...
Therefore, in micromachining application dominant are the operations where simple electrode-tool (i.e., cylindrical with spherical, or flat or tip, wire) can be applied [30,31]. The process is similar to milling and the machined shape results from the electrode-tool path. Thus, dimensions and the final shape of the part depends on the diameter ...

Abstract. Electrochemical machining is a relatively new technique, only being introduced as a commercial technique within the last 70 years. A lot of research was conducted in the 1960s and 1970s, but research on electrical discharge machining around the same time slowed electrochemical machining research. The main influence for the …
ABSTRACT. Micromanufacturing is the bridge between nano-and macromanufacturing. There is an increasing demand for miniaturized products such as microsystems, microreactors, fuel cells, and micromedical devices. Micromanufacturing involves techniques such as photolithography, chemical etching, plating, LIGA, and laser ablation.
