Abstract:
In a stencil mask, a conductive thin film has first openings in it. An insulating film is formed in the region of the conductive thin film excluding the first openings. A conductive support is formed on the insulating film. A second opening goes through the conductive support and insulating film and reaches the surface of the conductive thin film. A conducting member is formed in the second opening. The conducting member connects the conductive support and conductive thin film electrically.
Abstract:
A method and apparatus for improved stencil/screen print quality is disclosed. The stencil or screen assists in application of a printable material onto a substrate, such as an adhesive to a semiconductor die of a semiconductor wafer during a lead-on-chip (LOC) packaging process. In one embodiment, the stencil includes a coating applied to at least one surface of a pattern of the stencil or screen to retard running of the printable material onto the surface. In another embodiment, the stencil or screen includes a second coating applied to at least one other surface of the pattern to promote spreading of the printable material onto the substrate.
Abstract:
A substrate clamp ring has an edge exclusion lip with a variable bottom surface. At least a portion of that bottom surface has a height above the substrate contact level selected to minimize accumulation over time of deposited aluminum-copper alloy across lower portions of the bottom surface, and to allow the aluminum-copper alloy to be deposited to a thickness of at least 2 microns on each of a predetermined number of substrates without bridging. The height of the bottom surface at an innermost edge of the lip is preferably about 17 mils, while a height of the bottom surface over the substrate edge is preferably about 8.5 mils.
Abstract:
The invention relates to an intermediate component for protecting hangers associated with electrostatic coating processes. The component is an electrically conductive, pliable, tubular member, and inexpensive relative to the hanger which it serves to protect. The component lessens the cost associated with traditional hanger cleaning and preserves hanger life and integrity. The tubular member may have a longitudinal slit for installing the member over a cross bar of a hanger.
Abstract:
An assembly station for a sputter shield assembly provides a work bench for assembling and disassembling the sputter shield assembly. The shield assembly has a clamp shield facing downwards to hold the shield assembly which is turned over by 180 degrees, and includes at least three bottom rim support arms for supporting the clamp shield and bearing the weight of the shield assembly, and at least three inner rim retaining arms for contacting the inner rim formed by the shield and the clamp shield. The invention provides a changed support means for holding the shield assembly on the assembly station so that one person is enough to do the assembly and disassembly of the shield assembly, and thus save manpower and operation time.
Abstract:
Disclosed is an apparatus for protecting the walls of a row of cylinders of an engine block from contamination when the walls of the other row of cylinders of the engine block are thermally coated. For this purpose, the apparatus comprises a plurality of inflatable hollow body members that can be moved into the interior of the cylinders whose walls are to be protected and inflated once they are in position in the interior of the particular cylinders. The hollow body members comprise a dimensionally stable inner sleeve member that is enclosed by an inflatable elastic envelope member. The inflatable hollow body members are arranged in two groups located opposite to each other.
Abstract:
A method of mounting a deposition mask onto a flexible frame for use in vacuum deposition of material through a pealable deposition mask in forming an OLED, including the steps of providing a plate with the pealable deposition mask formed thereon; providing the flexible frame having border portions, such border portions defining a frame opening which corresponds to border portions on the pealable deposition mask; aligning and then securing the border portions of the flexible frame to the border portions of the pealable deposition mask and removing the flexible frame and secured pealable deposition mask from the plate; and mounting the flexible frame with the pealable deposition mask in a carrier which maintains planarity of the pealable deposition mask during subsequent vacuum deposition of material.
Abstract:
This invention relates to a device, such as a paint mat, removably attachable to the base of a paint can, for collecting spills and drips from the paint can during use. The paint mat includes an attachment means, such as a magnet, in the central portion thereof, for attachment to the base of the paint can. When attached, the paint mat extends beyond the perimeter of the paint can. The paint mat may include an aperture distal to the central portion but not extending past the perimeter of the base. The semi-rigid board also includes an advertisement on at least one side thereof and an extension therefrom so as to allow a brush to rest.
Abstract:
The present invention generally provides a physical vapor deposition chamber and a method for detecting a position of a shutter disk within a physical vapor deposition chamber. In one embodiment, a physical vapor deposition chamber includes a chamber body having a shutter disk mechanism disposed therein. A housing is sealingly coupled to a sidewall of the chamber body and communicates therewith through a slot formed through the sidewall. At least a first sensor is disposed adjacent to the housing and orientated to detect the presence of a shutter disk mechanism within the housing. In one embodiment, a method for detecting the position of a shutter disk within a physical vapor deposition chamber having a substrate support generally includes moving the shutter disk away from a substrate support, and changing a state of a first sensor in response to a position of an edge the shutter disk.
Abstract:
A mask frame assembly used in vacuum deposition of thin films of an organic electroluminescent device. The mask frame assembly includes a frame having an opening and at least two unit masks which each have at least one unit masking pattern portion in the direction of the unit mask and two edges which are fixed to the frame under tension.
