This paper presents experimental comparison of a modified silicon-on-glass (M-SOG) process to a previously-reported classical SOG (C-SOG) process based on the use of SOI wafers, yielding a stress free < 111 > silicon structural layer with desired structure thickness. The basic difference between these processes is the sequence of the step at which the silicon microstructures are defined by DRIE, making M-SOG more robust against critical dimension (CD) variations. Overall, M-SOG provides a simple, high yield, reliable, and robust solution for producing high performance MEMS inertial sensors, and these advantages are experimentally verified over C-SOG, both completed by following the identical process parameters and by using the same mask set.


Comparison of Two Alternative Fabrication Processes for a Three-Axis Capacitive MEMS Accelerometer
Tez, S.; Akın, Tayfun (Elsevier BV; 2012-09-12)
This paper presents a three-axis capacitive MEMS accelerometer implemented by fabricating lateral and vertical accelerometers in a same die with two alternative processes: a double glass modified dissolved wafer (DGM-DWP) and a double glass modified silicon-on-glass (DGM-SOG) processes. The accelerometers are implemented with a 35 mu m structural layer, and the three-axis accelerometer die measures 12mmx7mmx1mm in each process. Each process includes a second glass wafer which, not only allows implementing a...
Stepped-etching for preserving critical dimensions in through-wafer deep reactive ion etching of thick silicon
Alper, Said Emre; Aydemir, A.; Akın, Tayfun (2009-06-25)
This paper presents the experimental investigation of stepped deep reactive ion etching (DRIE) process in order to minimize critical-dimension (CD) variations due to local heating observed in through-wafer etch of 100 mum-thick, high aspect ratio silicon microstructures that are suspended over glass substrate. Classical methods of cooling the substrate, using a heat-sink layer, or increasing the thickness of sidewall passivation in general turns out to be insufficient for preventing excessive damage in crit...
Application of computer-aided injection moulding simulation for thermoplastic materials
Onalir, B; Kaftanoglu, B; Balkan, Raif Tuna (1998-01-01)
This paper presents the computer-aided simulation of an injection moulding process for thermoplastic materials. The reasons for using computer simulation for the injection moulding process are discussed together with description of the mould-filling and cooling phenomena. The paper also traces the difficulties in transferring the geometry of the part database from a computer-aided design environment to a computer-aided analysis environment by proposing several solutions for plastic products. Details of simu...
Modeling and fabrication of electrostatically actuated diaphragms for on-chip valving of MEMS-compatible microfluidic systems
Atik, Ali Can; Ozkan, Metin Dundar; Ozgur, Ebru; Külah, Haluk; Yıldırım, Ender (IOP Publishing, 2020-11-01)
This paper presents an analytical model to estimate the actuation potential of an electrostatic parylene-C diaphragm, processed on a glass wafer using standard microelectromechanical systems (MEMS) process technology, and integrable to polydimethylsiloxane (PDMS) based lab-on-a-chip systems to construct a normally-closed microvalve for flow manipulation. The accurate estimation of the pull-in voltage of the diaphragm is critical to preserve the feasibility of integration. Thus, we introduced an analytical m...
Comparison of Natural Halloysite With Synthetic Carbon Nanotubes in Poly(lactic acid) Based Composites
Erpek, Canan Esma Yeniova; ÖZKOÇ, GÜRALP; Yılmazer, Ülkü (Wiley, 2017-11-01)
The objective of this study is to compare the mechanical properties, structure and degradability of the nanocomposites prepared with tubular nanofillers, halloysite (HNT) and carbon nanotube (CNT) in poly(lactic acid) (PLA), and thermoplastic polyurethane (TPU) toughened PLA (T-PLA) matrices. In the PLA matrix, CNT increased, whereas HNT decreased the tensile strength with increasing filler content. Also, the elongation at break and impact strength decreased with increasing CNT content, but these properties...
