1 de feb. de 2014 · Electrostatic chuck (ESC) is one of the key components in IC manufacturing process, which applies the principle of electrostatic adsorption to clamp the wafer on its surface. In such a system ...
This paper proposes electrostatic chuck electrode design method for uniform chucking force distribution. To design the chuck, we combine continuum sensitivity analysis and adaptive level set method. Continuum sensitivity analysis derives the sensitivity at the electrode surface, and adaptive level set method clearly demonstrates the changed shape. The design objective is to obtain uniform ...

Bipolare Störung ist die etablierte Kurzbezeichnung für bipolare affektive Störung (BAS). Bei der BAS handelt es sich um eine psychische Erkrankung, die zu den Stimmungsstörungen (Affektstörungen) gehört.. Die Krankheit zeigt sich durch extreme, zweipolig entgegengesetzte (= bipolare) Schwankungen, die Stimmung, Antrieb, Denken, Handeln und Aktivitätsgrade betreffen.
ESC is being used widely in the semiconductor processes such as ion implantation, plasma etch, thin film deposition, lithography and inspection. FIGURE 1. Aluminum mono-polar and polyimide bi-polar chucks. In this particular case an ESC is used to handle solar wafers (156mm square by 150um thick) at 2,400 wafers per hour throughput.
