etching

While Rembrandt was alive, collectors already sought to possess every version or state of a particular etching.

Prior to the development of wavelength-dispersed spectroscopy on an electron microprobe analyzer and energy-dispersed spectroscopy on a scanning electron microscope, selective etching experiments were conducted as an aid to intermetallic phase identification.

Deep silicon etching is a critical step in the fabrication of silicon-based MEMS.

During etching, the San Diego chemists project a black-and-white slide-in the case of these photos, George Washington's face from a dollar bill - onto the silicon wafer through a lens that reduces the size of the image.

Following is the examination of gray and ductile iron micrographs before etching.

Deep bulk micromachining (etch depths >200mu m for through-wafer etching finds applications for fabrication of microcomponents such as micro-springs, through-the-wafer interconnects, and micro-tips for atomic force microscopy.

Doan and Sailor modified the process by projecting a high-contrast pattern -- and, later, someone's picture -- onto the silicon during etching.

In both high-k dielectric and metal gate etch, Hitachi is having great success etching these materials with no chamber wall residue to cause defects.

Initially, chip designers and manufacturers tailored chips without really knowing what goes on during the etching process.

E[acute accent]The Applied Tetra II Mask Etch system offers high-productivity processes for both chrome and dielectric mask etching.

Using etching techniques borrowed from the integrated-circuit electronics industry, they can modify the surfaces of lenses to improve their optical properties.

Unaxis Wafer Processing has developed a leading market position in each of its served markets which include: Advanced Packaging, Thin Wafer and Multi-Level Metallization, Photomask Etching and Compound Semi, MEMS and Nanotechnology.

Research Laboratory allows the etching of these microstructures--some only one-hundredth the width of a human hair.

The current Omega fxP platform at Fraunhofer is already equipped with two M0RI process modules for dielectric and polysilicon etching.

a leading DRAM manufacturer, has selected the Applied Centura(R) AdvantEdge(TM) system in its recent fab investment cycle for all of its silicon etching applications, including next-generation high k and metal gate structures.
