Abstract:
PROBLEM TO BE SOLVED: To provide a method and an apparatus for facilitating measures for any problem that contamination or damage is generated in a projection lens or its peripheral region due to gas emission of volatile components in resist during radiation exposure. SOLUTION: This lithography system projects a patterned radiation beam on the target of a substrate containing a radiation photosensitive layer by a radiation source, a patterning structure and a projection system is provided with a gas flashing system for supplying air from a region between the projection system and the substrate in order to remove gas spread from the target section while the target section is exposed by the patterned radiation beam.

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:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a device, which minimizes or eliminates at least a portion of error sources in positional adjustment of adjacent exposure portions. SOLUTION: A projection field is selected so as to minimize a stitching error, in order to print a layer of an extended device, i.e., a device extending into a plurality of target portions or dies. It is desirable that the projection field is selected based on the data characterizing a used projection lens, and in such a way that the difference between positional errors of a projected image at the side opposite to the field is minimized.
