The effect of titanium dioxide addition on bonding strength of CaO-P2O5 -Na 2O-TiO2glass-ceramic system was investigated as a coating on titanium substrate. Thus, different amounts of TiO2 (2, 3.5 and 5mol %) were added to the base glass batch composition. The prepared glaze slips were applied on the substrate by dip coating method, dried and then heat treated at various temperatures. After tha...

Anodic bonding of silicon to glass always involves heating the glass and device to high temperatures so that cations become mobile in the electric field. We present a simple way of bonding thin silicon samples to borosilicate glass by means of heating from the glass side while locally cooling heat-sensitive areas from the silicon side. Despite the high thermal conductivity of silicon, this meth...

In this paper, a single-mask substrate transfer process for the fabrication of high-aspect-ratio (HAR) suspended structures is presented. The HAR silicon structures are fabricated using a deep reactive ion etching (DRIE) technique and then transferred to a glass wafer using silicon/thin film/glass anodic bonding and silicon thinning techniques. The HAR structures are released using self-aligned...

(2014). Customized glass sealant for ceramic substrates for high temperature electronic application. Abstract This study investigates the ceramic to ceramic bonding, using composite glass frit as the binding layer that is able to tolerate a high temperature environment for ruggedized microelectronic applications. Shear strength measurements were carried out at both ambient room and high tempera...

Oxygen plasma treatment has been used extensively to bond polydimethyl siloxane to polydimethyl siloxane or glass in the rapid prototyping of microfluidic devices. This study aimed to improve the bonding quality of polydimethyl siloxane to passivated silicon using oxygen plasma treatment, and also to evaluate the bonding quality. Four types of passivated silicon were used: phosphosilicate glass...

This thesis has characterized the applicability and limitation of PDMS micromolding and the substrate bonding techniques including both anodic (Si-glass) and thermal fusion (glass-glass) bonding, in fabricating sub-100-nm thick nanofluidic channels, which will be used for a controlled experimental study of molecular and fluidic transport in confined space. It is found that the fabrication of na...

introduction: the aim of the present study was to evaluate the effect of glass ceramic insert in the sandwich technique to reduce microleakage in class ii composite resin restorations. methods: sixty sound human upper second premolars were selected and randomly divided into six groups (n=10). class ii box-only cavities were prepared in distal aspects of each tooth with gingival margin located a...
