ABSTRACT

Shallow trench isolation (STI) requires a high quality oxide with superior fill capability provided by High Density Plasma (HDP) oxide. Unfortunately, the HDP deposition process can create large within die topographies that are difficult to polish directly using conventional silica slurries. As a result, etch back integration schemes have traditionally been incorporated for STI polish. A more revolutionary approach is the use of Fixed Abrasive (FA) CMP . FA CMP allows direct STI polish with good planarizatio ....etc

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc

ABSTRACT
Study of new and cost effective finishing processes has alwaysbeen an area of keen interest to overcome the difficulties ofexisting finishing process. Magnetic Abrasive Finishing(MAF) is a process in which a mixture of non-ferromagneticabrasives and ferromagnetic iron particles is used to dofinishing operation with the aid of magnetic force. The ironparticles in the mixture are magnetically energized using amagnetic field. The iron particles form a lightly rigid matrixin which the abrasives are trapped. This ....etc

Micron sized polymeric particles in custom designed geometries and with tunable chemical anisotropy are expected to enable a variety of new technologies in diverse areas such as photonics, diagnostics and functional materials. Current approaches for particle synthesis are either batch processes or flow-through microfluidic schemes that are based on two-phase systems, limiting the throughput, shape and functionality of the particles. We report a one-phase method called Stop Flow Lithography (SFL) that combines the advantages of microscope projec ....etc
