In this paper we present the planarization process of a CMOS chip for the integration of a microelectromechanical systems (MEMS) metal mirror array. The CMOS chip, which comes from a commercial foundry, has a bumpy passivation layer due to an underlying aluminum interconnect pattern (1.8 μm high), which is used for addressing individual micromirror array elements. To overcome the tendency for t...

This paper describes a planarization procedure to achieve a flat CMOS die surface for the integration of a MEMS metal mirror array. The CMOS die for our device is 4 mm x 4 mm and comes from a commercial foundry. The initial surface topography has 0.9 μm bumps from the aluminum interconnect patterns that are used for addressing the individual micro mirror array elements. To overcome the tendency...

The third article of the series devoted to application nanomaterials and nanotechnologies in industry general and, first all, metallurgy, materials science foundry is presented. This deals with use for improvement ferrous non-ferrous alloys by micro-alloying modifying methods, as well synthesis new composite materials. results research on C-B-Fe composites obtained at Belarusian State Technolog...

high intensity optical radiation can cause damage to the eye and intense radiation in the range of 770-1400 nm can cause thermal retinal damage. in the workplaces where there are high temperature sources, the workers in front of these hot  sources without bright light maybe exposed to the  intense ir radiation, thus regular measurement of these radiations seems crucial. measurement of ir radiat...

BACKGROUND Foundry work is associated with serious occupational hazards. Although several studies have investigated the health risks associated with foundry work, the results of these studies have been inconsistent with the exception of an increased lung cancer risk. The current study evaluated the mortality of Korean foundry workers due to malignant and non-malignant diseases. METHODS This s...

Compared with pure aluminum and wrought alloys, Al foundry alloys are more difficult to be anodized. The high content of alloying elements prevents the uniform growth oxide layer enhances embedding defects in anodic film. microstructure substrate anodizing parameters play a key role final quality layer. Variations chemical composition, casting process, pre‐ post‐anodizing treatments can signifi...
