Advanced Laser Scribing for Emerging LED Materials

Additional Conferences (Device Packaging, HiTEC, HiTEN, and CICMT), 2011
Lasers are becoming increasingly important in today's LED revolution and are essential for increasing the efficiency and reducing manufacturing cost of LEDs. Diode pumped solid state lasers excel in scribing horizontal type LEDs on sapphire, silicon, silicon carbide, III-nitrides (gallium nitride and aluminum nitride), as well as III-V semiconductors ...

Optimization of laser scribing for thin-film photovoltaics

Conference Record of the Twenty Fifth IEEE Photovoltaic Specialists Conference - 1996, 1996
In this paper, the authors report on studies of four different lasers for the scribing of thin-film photovoltaic materials including CdTe, CIS, SnO/sub 2/, ZnO, and Mo. They have used cw-lamp-pumped and flashlamp-pumped Nd:YAG lasers (/spl lambda/=532/1064 nm), a copper-vapor laser (511/578 nm), and an XeCl-excimer laser (308 nm), with pulse durations ...

Mechanically inspired laser scribing of thin brittle materials

Journal of the American Ceramic Society, 2017
Abstract Laser processing of thin flexible ceramics and glasses is challenging due to the incurred brittleness and unfavorable thermal and optical properties of such materials. We describe an alternative laser cutting method which utilizes surface stress raisers to cleave brittle substrates along a defined path.

Parameters optimization and control in precision laser scribing

SPIE Proceedings, 2005
The positional precision of laser scribing and laser marking in precision metrological tools, such as scale plate and scale dial, is of the order of µm. The control of scribing must be very accurate. The laser beam parameters, focal length of the lens, and the position of the focal spot must be carefully selected and accurately controlled.

Laser‐Scribed Battery Electrodes for Ultrafast Zinc‐Ion Energy Storage

Advanced Materials
AbstractAqueous Zn batteries are promising for large‐scale energy storage but are plagued by the lack of high‐performance cathode materials that enable high specific capacity, ultrafast charging, and outstanding cycling stability. Here, a laser‐scribed nano‐vanadium oxide (LNVO) cathode is designed that can simultaneously achieve these properties.
