Chip-level CMP modeling is investigated to obtain the post-CMP film profile thickness across a die from its design layout file and a few film deposition and CMP parameters. The work covers both HDP and conformal CVD film. The experimental CMP results agree well with the modeled results. Different algorithms for filling of dummy structure are compared. A “smart” algorithm for dummy filling is pr...

Blown Film Extrusion is the primary technology used to make plastic films especially for the packaging industry. Its machines produce protective films used in many industries including food and pharmaceuticals – that extend product shelf life and improve consumer appeal. Products such as trash bags, frozen food packaging, shrink wrap, stretch film labeling, form, fill and seal packaging, medica...

I T HAS been recognized that intracavi-tary irradiation is essential in the treatment of carcinoma of the uterine cervix. Since the beginning of the present century3 many applicators have been used to irradiate the uterus and vagina and later several afterloading techniques have been de-scnibed. " 4 Some of the techniques involve the use of remote control5 " and linear distribution of the sourc...

Fluorinated amorphous carbon films exhibit superlow friction under vacuum, but are prone to catastrophic failure. Thus far, the intrinsic failure mechanism remains unclear. A prevailing view is that the failure of amorphous carbon film results from the plastic deformation of substrates or strong adhesion between two contacted surfaces. In this paper, using first-principles and molecular dynamic...

Internal friction in aluminum thin films on silicon substrates has been measured uaween 180 and 360 K as a function of strain amplitude. The amplitude dependence of internal fnction in the aluminum films has been evaluated from the data on the film-substrate composite and further converted into the plastic strain of the order of as a function of the effective stress on dislocation motion. The m...

In a collaboration between Pennsylvania State University and Princeton University, we have been laying the foundations for flexible display technology. Flexible substrates including plastic or steel foil, backplanes of organic or silicon transistors, and directly printed RGB organic light emitting diodes are issues central to this collaboration. We present an overview of key recent results. Sil...

The development of low temperature, thin film transistor processes that has enabled flexible displays also presents opportunities for flexible electronics and flexible integrated systems. Of particular interest are possible applications in flexible, low metal content, sensor systems for unattended ground sensors, smart medical bandages, electronic ID tags for geo-location, conformal antennas, n...

We analyzed dietary habits and presence of plastic in 589 boluses of Glaucous-winged Gulls (Larus glaucescens) as one of two studies on the impact of plastics on marine life in the US Salish Sea. Volunteers dissected boluses collected (2007-2010) from Protection Island, Washington. Components were separated into 23 food and non-food categories. Plastic was found in 12.2% of boluses, with plasti...

The target was to study and develop industrially suitable methods to apply thermoplastic coatings on plywood. Typically, wear and climatic resistance for wooden sheets, such as chip board and plywood, is achieved by thermosetting resin coating (e.g. phenolformaldehyde). However, economical and environmental issues are driving towards thermoplastic coatings (e.g. polyethylene) in such products. ...
