Localised laser joining of glass to silicon with BCB intermediate layer

Laser Joining of Continuous Glass Fiber Composite Pre-forms

A laser fusion joining method is investigated for the purpose of through thickness strengthening of fiber pre-forms used in the vacuum infusion fabrication of thick composite structures. Laser joining is achieved without filler materials to replace adhesives, pins or stitches used in conventional composite fabrication. A two step joining process is developed to fuse fibers within a single bundl...

Transmission Laser Bonding of Glass with Silicon Wafer

As a microassembly and an encapsulation technique, wafer bonding offers a unique opportunity to combine different materials. Transmission laser bonding not only can satisfy wafer level bonding requirements, but can also be directly implemented into the existing automatic semiconductor fabrication line. In this paper, a laser-induced wafer bonding technique for micro-electro-mechanical systems (...

Laser scanning tomography of localised nerve fibre layer defects.

AIMS Retinal nerve fibre layer photography is a well established method to qualitatively document early structural changes which might be induced by primary open angle glaucoma. The aim was to analyse localised retinal nerve fibre layer (RNFL) defects in a new quantitative way with respect to surface topography, defect width, and surface reflectivity by means of the technique of confocal scanni...

Laser Micromachining of Glass, Silicon and Ceramics. a Review

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...
