We discuss the design, fabrication, and testing of prototype horn-coupled, lumped-element kinetic inductance detectors (LEKIDs) designed for cosmic microwave background studies. The LEKIDs are made from a thin aluminum film deposited on a silicon wafer and patterned using standard photolithographic techniques at STAR Cryoelectronics, a commercial device foundry. We fabricated 20-element arrays,...
Background and Aim: Ontologies facilitate data integration, exchange, searching and querying. Open Biomedical Ontologies (OBO) Foundry is a solution for creating reference ontologies. In this foundry, the design of ontologies is based on established principles which allow for their interactions as a single system. The purpose of this study is to determine the main features of ontologies develop...
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...
