A clasp having a wafer-like body releasably holds together thin flexible handles of a bag for carrying articles. The body includes a pair of opposing lobes that define a channel extending from a peripheral edge to an interior aperture. A wall of the aperture defines two generally V-shaped niches, each on opposite sides of the channel adjacent the lobes. The handles of the bag, inserted through the channel to the interior aperture, engage the niches for holding the bag substantially closed when being operated for enveloping articles. A method of releasably maintaining an entrance of a bag substantially partially closed is also disclosed.

Method and device for containing articles in a bag

A method is disclosed for cleaning microelectronic surfaces using an aerosol of at least substantially solid argon or nitrogen particles which impinge upon the surface to be cleaned and then evaporate and the resulting gas is removed by venting along with the contaminants dislodged by the cleaning method.

Surface cleaning using an argon or nitrogen aerosol

Apparatus and a method for performing high resolution optical imaging in the near infrared of internal features of semiconductor wafers uses an optical device made from a material having a high index of refraction and held in very close proximity to the wafer. The optical device may either be a prism or a plano-convex lens. The plano-convex lens may be held in contact with the wafer or separated from the wafer via an air bearing or an optical coupling fluid to allow the sample to be navigated beneath the lens. The lens may be used in a number of optical instruments such as a bright field microscope, a Schlieren microscope, a dark field microscope, a Linnik interferometer, a Raman spectroscope and an absorption spectroscope.

Apparatus and a method for high numerical aperture microscopic

A thermophoretic filter cell for the filtering of particles from a liquid is constructed in a particular manner so that the liquid introduced into the filter acts as the heat sink. The cell is designed so that the thermophoretic velocity of the particles in the liquid equals or exceeds the velocity (flow rate per unit area) at which the liquid is passing through the filter.

Thermophoretic filtering of liquids

A method is disclosed for cleaning microelectronics surfaces using an aerosol of at least substantially solid argon particles which impinge upon the surface to be cleaned and then evaporate and the resulting gas is removed by venting along with the contaminants dislodged by the cleaning method.

Surface cleaning using a cryogenic aerosol

An apparatus and method for electrostatic removal of micron and sub-micron sized contaminant particles is disclosed herein. The apparatus and method comprise creating a potential difference with a megavolt/cm electrostatic field between two conducting bases in a predetermined geometrical relation to each other. An insulator (e.g. a dielectric film) is maintained at or near contact between one of the bases and the surface to be cleaned to electrostatically remove particles from said surface. The bases can be made to move relative to each other and the surface to be cleaned.
