Abstract:
PROBLEM TO BE SOLVED: To provide a device which forms a ring-shaped resist pattern for forming bumps in a substrate by electrodepositing. SOLUTION: The apparatus includes a substrate holder arranged to hold a substrate W coated at least in part with resist R, and a heating device configured to heat an area of the resist. The relative movement between the substrate holder and the heating device HD is possible. The movement is arranged such that, in use of the ring seal forming apparatus, the area of resist heated by the heating device HD is ring-shaped, so that the ring-shaped resist pattern can be formed.

Abstract:
PROBLEM TO BE SOLVED: To provide a method and a system for three-dimensional alignment for wafer scale integration. SOLUTION: A board bonding system is provided with first and second board tables to hold first and second boards, and a controller. The first board is equipped with a first device having a first contact pad, and the second board is equipped with a second device having a second contact pad. The wafer bonding system is designed to conduct bonding of the first and second devices so that a circuit can be formed by the first and second devices. First and second board tables ST and STb are respectively provided with a position sensor to measure optical signals generating on alignment markers WM1, WM1', WM2, and WM2', and WM1b, WM1b', WM2b and WM2b' of the first and second boards. Furthermore, they are provided with first and second actuators ACT and ACTb to change the position and the orientation of the respective board tables. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
An imprint lithography apparatus comprising a template (34), a substrate table (31) and an alignment system. (35, 36, 37) arranged to align. the template (34) to a substrate alignment t mark (39; 39`) provided on a substrate (30). The substrate table (31) is arranged to support the substrate (30) having a first surface (32) to be imprinted andd a second surface (50) facing the substrate table (31). The apparatus is characterised in that the substrate alignment mark (39; 39') is provided on the second surface (50) of the substrate (30), and that the substrate table (31) further comprises a substrate table optical. system for allowing the substrate alignment mark (39; 39') to be viewed by the alignment system. (35. 36, 37). The invention further extends to a device manufacturing method and a device manufactured thereby.
Abstract:
A plurality of markers are printed in resist on a substrate at a range of angles relative to a crystal axis of the substrate. The markers are etched in to the substrate using an anisotropic etch process, the markers being such that after the etch their apparent positions are dependent on their orientation relative to the crystal axis. The apparent positions of the markers are measured and from this the orientation of the crystal axis is derived.
