This paper presents results of a systematic investigation to characterize the sealing of micromachined cavities using chemical vapor deposition (CVD) methods. We have designed and fabricated a large number and variety of surface-micromachined test structures with different etch-channel dimensions. Each cavity is then subjected to a number of sequential CVD deposition steps with incremental thic...

BACKGROUND Evaluate the influence of different hybridization bonding techniques of a self-adhesive resin cement. MATERIAL AND METHODS 30 human health molars were divided into six groups (n=10). The specimens received three longitudinal sections, allowing insertion of central cuts in PVC matrices. Each group received a different dentin pretreatment according to the manufacturer's recommendatio...

During the months preceding the etch release, I worked on several large-scale QA tasks using an computing grid, including rebuilds of all packages in Etch, piuparts runs on all packages in Etch, etc. This talk will briefly describe what was done and how, and then will discuss various directions for future improvements, including changes needed to run such tasks on a regular basis, and to make t...

The authors demonstrate the production of low loss enhanced index contrast waveguides by reactive ion etching of IPGTM polysiloxane thin films. The use of a silica mask and CHF3 /O2 etch gas led to large etch selectivity between the silica and IPGTM of !20 and etch rates of !100 nm /min. This work indicates that compact optical circuits could be successfully fabricated for telecommunication app...

In this work, the inductively coupled plasma etching technique was applied to etch the barium titanate thin film. A comparative study of etch characteristics of the barium titanate thin film has been investigated in fluorine-based (CF4/O2, C4F8/O2 and SF6/O2) plasmas. The etch rates were measured using focused ion beam in order to ensure the accuracy of measurement. The surface morphology of et...

This study aimed to evaluate the effect of adhesive application method on durability enamel bond and thickness layer. A new-generation two-step universal system, G2-Bond Universal, two conventional systems were utilized. The shear strength bovine was measured after thermal cycling in both etch-and-rinse self-etch modes. Fifteen specimens divided into three groups as follows: Group I, wherein a ...

Background/Aim. Although essential oil-containing mouth rinses have some advantages, it is not well-known what effects they on the bond strength of universal resin adhesives system to enamel. The aim study was evaluate effect rinse enamel adhesive system. Methods. ninety-six bovine incisors were used. teeth divided into four different groups according control group and 3 rinses: Group I (Contro...
