Abstract:
A bonding method and a bonding substrate are provided. The bonding substrate is applied to a silicon wafer having the same shape. The bonding method includes the following steps. Firstly, the optical glass substrate is processed to form a first alignment mark. Then, an adhesive layer is coated on a surface of the optical glass substrate. The adhesive layer on the surface of the optical glass substrate is partially removed, thereby defining an adhesive structure. According to the first alignment mark of the optical glass substrate and a second first alignment mark of the silicon wafer, alignment between the optical glass substrate and the silicon wafer is performed. Afterwards, the optical glass substrate and the silicon wafer are bonded together through the adhesive structure.
Abstract:
This invention relates to an adhesive article which provides air egress. Air egress is provided by supplying a route, such as areas of no initial adhesion for the air to flow out from under the construction. The invention relates to an adhesive article comprising a facestock having a front surface and a back surface, a continuous layer of adhesive having an upper surface and a lower surface wherein the upper surface of the adhesive layer is adhered to the back surface of the facestock, and a plurality of spaced-apart non-adhesive material which is in contact with the lower surface of the adhesive layer. These articles have usefulness as industrial graphics images, as well as decorative coverings, etc. The articles provide air egress and optionally repositionability and slideability.
Abstract:
A medical adhesive tape in which a number of bare spots are provided through the tape to vary the strength of the bond of the tape to a surface. The number of bare spots as well as their size and location can be varied to modify the adhesive strength with which the tape is held onto the patient.
Abstract:
The tile installation system provides a system for installing an architectural covering material to a substrate surface utilizing a plurality of release sheets where each release sheet has a top side surface and a bottom side surface. A plurality of discrete adhesive substrate portions are positioned on the top side surface of the release sheet, wherein the top side surface of the release sheet has a stronger bonding affinity with the plurality of adhesive substrate portions than the bottom side surface.
Abstract:
A wafer mount tape, a wafer processing apparatus and an associated method of using the wafer mount tape for use in wafer thinning operations is presented. The wafer mount tape includes a tape body, a first adhesive member and a second adhesive member. The tape body has a first region, a second region and a third region. The first region of the tape body is for being disposed onto a wafer. The second region of the tape body is defined along a periphery of the first region. The third region of the tape body is defined along a periphery of the second region. The first adhesive is member is disposed at the first region. The second adhesive member is disposed at the third region.
Abstract:
Methods of making cut adhesive articles are described. The methods involve: providing a crosslinked pressure sensitive adhesive layer disposed on a substrate, embossing a surface of the crosslinked pressure sensitive adhesive layer to form a microstructured crosslinked pressure sensitive adhesive layer having a microstructured adhesive surface, and die cutting the microstructured crosslinked pressure sensitive adhesive layer.
Abstract:
An adhesive article comprising a first substrate having thereon an adhesive layer, wherein the adhesive layer comprises a cured adhesive composition of a multifunctional ethylenically unsaturated siloxane polymer; and the first substrate comprises a polymer film, paper, a metal film, glass, ceramic, or a combination thereof; and wherein the adhesive layer has a microstructured surface that is substantiously continuous, and wherein the microstructured surface forms an array or pattern. The adhesive article is used to make laminated articles that spontaneously wet, and when applied to a substrate, remain removable or repositionable, even after long periods of time. The adhesive composition may be used in transfer adhesive films, and in laminated articles suitable for use in optical applications.
Abstract:
The easily applicable adhesive sheet of the invention is characterized by having a base sheet, and an adhesive layer which is provided on the base sheet and which has, in a surface portion thereof, a plurality of air passages having grooves opening on an end edge portion of the base sheet, wherein each air passage includes therein numerous island-like protrusions whose tops are flush with the surface of the adhesive layer, and the island-like protrusions are arranged such that such that any circle inscribed in the grooves defined by side walls of the air passage and those of the protrusions has a diameter of 5 to 90 μm at the level of the surface of the adhesive layer. The invention provides an easily applicable adhesive sheet which is smoothly applied to an adherend without formation of “blisters,” and which exhibits excellent appearance after application thereof to the adherend.
Abstract:
The present invention disclose a pressure-sensitive adhesive sheet having the adhesive layer on at least one surface of the substrate, characterized in that in particular the above adhesive layer has a number of trunk-like grooves which lead to the end of the above sheet, and a number of branch-like grooves with closed terminals which branch from the trunk-like grooves. This structure provides effects in that it can be applied easily and smoothly without retaining air when adhering to an adherend and additionally the appearance of the pressure-sensitive adhesive sheet is not damaged after adhering.
Abstract:
A process for affixing an insulating label to a container involves applying a thermoplastic hot-melt adhesive to a first edge of the label and applying a thermoplastic hot-melt adhesive and a thermosetting adhesive to a second edge of the label. The insulating label is applied to a container, and provides improved heat resistance, thereby reducing occurrences of delamination during subsequent heating of the container.
