The Cosmological Hoe

The hoe—the sound of the word is sweet...the hoe makes everything prosper, the hoe makes everything flourish. The hoe is good barley...the hoe is brick moulds, the hoe has made people exist. It is the hoe that is the strength of young manhood. The hoe and the basket are the tools for building cities. It builds the right kind of house, it cultivates the right kind of fields. It is you, hoe, that...

Analysis of DRIE Uniformity

A quantitative model capturing pattern density effects in Deep Reactive Ion Etch (DRIE), which are important in MEMS, is presented. Our previous work has explored the causes of wafer-level variation and demonstrated die-to-die interactions resulting from pattern density and reactant species consumption. Several reports have focused on experimental evidence and modeling of feature level (aspect ...

Deep Reactive Ion Etching (DRIE)

The role of professional organizations in nursing advancement.

Die rol van professionele verenigings in die ontwikkeling van die verpleegberoep word bespreek. Eerstens word die drie hoofkomponente van die onderwerp, naamlik rol, ontwikkeling en professionele verenigings gedefinieer. Daarna deel die skrywer met die leser hoe sy ’n model vir verpleegstersverenigings ontwikkel het. Die uiteindelike model, die dinamiese verbruiker-inhoud-model maak voorsiening...

Characterization and Modeling of Non-uniformities in DRIE

Our previous work on spatial non-uniformities in deep-reactive ion etch (DRIE) has provided a method by which an etching tool and associated “recipes” of operating parameters may be pre-characterized [1]. That work allowed the wafer-average pattern opening density (or “loading”) to be related to waferscale etch rate variations. Such variations have been attributed to loading-dependent interacti...
