In the area of Micro Electro Mechanical Systems (MEMS), bulk micromachining and surface micromachining are two main technologies. Bulk micromachining defines structures by selectively etching inside a substrate while surface micromachining uses a succession of thin film deposition and selective etching on top of a substrate. The two technologies are quite different, resulting in different dimen...

This paper presents a fabrication process that integrates polysilicon surface micromachining and deep reactive ion etching (DRIE) bulk silicon micromachining. The process takes advantage of the design flexibility of polysilicon surface micromachining and the deep silicon structures possible with DRIE. As a demonstration, a torsional actuator driven by a combdrive moving in the out-of-plane dire...

Ultrafast laser micromachining is a promising candidate for microand nano-fabrication technology. Due to the high precision of femtosecond ablation, laser-machined features can be added to devices prototyped by lithography. To accomplish that, parametric studies of laser interrogation of materials of interest are necessary. We present femtosecond laser ablation studies of glass, PDMS, fused sil...

A brief review is focused on laser micromachining of materials. Micromachining of materials is highly widespread method used in many industries, including semiconductors, electronic, medical, automotive, communication and aerospace. This method is a promising tool for material processing with micron and submicron resolution. In this paper micromachining of glass, silicon and ceramics is conside...

Micromachining can be considered a fabrication technology for building devices with feature sizes from a few microns to a few mils, often with moving parts. MicroeElectroMechemical Systems (MEMS) is a term often used interchangeably with micromachining. MEMS devices, however, are distinguished from micromachining by their mechanical nature, because moving parts are often a required component to...

0. Introduction Micromachining techniques have been developed on the basis of the microelectronic fabrication technology. Microfabrication is a generic term that is also used to imply micromachining. What makes micromachining different from microelectronic fabrication technology is the need to have a released mechanical structure that can move either like a rigid body (as in translation, rotati...

Applications of laser micromachining to the manufacture and prototyping of MEMS and MOEMS devices are presented. Examples of microturbines, biofactory on a chip, microfluidic components and microoptical elements manufactured by laser micromachining are described.
