Abstract:
PROBLEM TO BE SOLVED: To provide a simple method for processing a workpiece remarkable in points that a solid material is uniformly formed, and the workpiece and a workpiece carrier are easily separated, and also to provide the workpiece carrier particularly used for this method. SOLUTION: A description is particularly made on a method for fixing the processing workpiece 52 to the workpiece carrier 10 by using the solid material 62. This workpiece carrier 10 is composed of a porous substance (for example, porous ceramics). A wafer is easily used in processing by this processing method. This workpiece 52 is also easily separated by using a solvent of the workpiece carrier 10. COPYRIGHT: (C)2004,JPO&NCIPI
Abstract:
Disclosed is, among other things, a method in which a workpiece (14) is fastened to a workpiece support (12) with the aid of connecting means (18, 20), the workpiece (14) and the workpiece support (12) being joined together using an annular connecting means (18, 20). The resulting compound is machined, whereupon the machined workpiece (14) is separated from the workpiece support (12), making it possible to create a particularly simple machining process.

Abstract:
The invention relates to a method wherein a resist layer (12) is applied to a base layer (24). The resist layer (12) is made of an adhesive material, the adhesive force thereof either reducing or increasing during radiation. Removal of residue of the resist layer (12) is made easier due to said method.
Abstract:
A method of making an integrated circuit includes providing a semiconductor wafer having a first surface and a second surface opposite the first surface, at least one of the first surface and the second surface including a metallization layer deposited onto the surface. The method additionally includes forming a first trench in the semiconductor wafer extending from one of the first surface and the second surface toward an other of the first surface and the second surface. The method further includes sawing a second trench in the other surface until the second trench communicates with the first trench, thus singulating the integrated circuit from the semiconductor wafer.
Abstract:
A method of fabricating a semiconductor chip includes the providing an adhesive layer on the outer area of the active surface of a device wafer and attaching a rigid body to the active surface by the adhesive layer. The device wafer is thinned by treating the passive surface of the device wafer. A first backing tape is connected to the passive surface of the device wafer. The outer portion of the rigid body is separated from the central portion of the rigid body and the outer portion of the device wafer is separated from the central portion of the device wafer. The central portion of the rigid body, the outer portion of the device wafer and the outer portion of the rigid body are removed from the first backing tape. The device wafer may be diced into semiconductor chips.
Abstract:
The component (10) has an integrated component (12) with thinned wafers such as semiconductor substrates e.g. single crystal semiconductor substrates. A layer region (14) is electrically conductively arranged at the wafers, where the layer thickness of the layer region is larger than 10 micrometers or larger than 50 micrometers. The wafers and the layer region have a same contour at a boundary layer between the wafers and the layer region. A housing body (26) is arranged to the wafers and the layer region. An independent claim is also included for a method for manufacturing an electronic component.
Abstract:
To increase the scratch resistance of a surface passivation, in particular, for fingerprint sensors, a antifrictional layer is applied to reduce the shearing forces. The antifrictional layer includes fat, oil, surfactants and/or wax. The antifrictional layer is preferably an emulsion including water, paraffin oil, propylene glycol, stearic acid, palmitic acid, TEA, beeswax, carbormer 954, methylparaben, propylparaben and possibly perfume.
