Patent number: 8594824Abstract: A method for patterning a workpiece in a direct write machine in the manufacturing of a multilayer stack, wherein a first circuit pattern comprising patterns for connection points is transformed according to determined fitting tolerances to fit to connection points of a second circuit pattern and to circuit pattern(s) of specific features such as random placed dies, or group of dies, on or in the workpiece. The second layer may be a previously formed layer or a layer to be formed on the same workpiece or on a different workpiece for the stack.

Patent number: 7705965Abstract: The present disclosure relates to formation of latent images in a radiation sensitive layer applied to a substrate that is transparent to or transmissive of radiation at the exposing wavelength. In particular, it relates to so-called backside lithography, in which the final lens of an exposing system is positioned to project electromagnetic radiation through a first side of the transparent substrate and expose a radiation sensitive layer that overlays a second side of the transparent substrate that is opposite the first side. Five alternative embodiments for further treatment to form a radiation opaque layer corresponding to the latent image (the image or its inverse) are described. These methods and corresponding devices are useful for producing masks (sometimes called reticles), for producing latent images in semiconductor devices and for forming features of semiconductor devices using masks.Type: GrantFiled: May 15, 2007Date of Patent: April 27, 2010Assignee: Micronic Laser Systems ABInventors: Per-Erik Gustafsson, Ulric Ljungblad

Patent number: 5800658Abstract: The present invention is for method and means by the manufacture of a product of expanded polymer, by which is obtained a weight per unit volume which is essentially lower than that of homogeneous expanded material. The starting material according to the invention can be either a specifically manufactured starting material or scrap and recovered material. The pieces of expanded polymer are supplied in controlled quantities through a feeder to a space for the application of glue drops which are sprayed into the space from one or more dies. In the space the pieces of polymer are dried by means of micro-wave energy which is obtained from an energy generator and magnetrones. The dried pieces then are discarded from the space together with the air flow through the opening. By the manufacture of a product according to the invention one starts from the pieces with glue applied to them as described above. The pieces are put into a mould wherein they are pressed against each other.Type: GrantFiled: October 8, 1997Date of Patent: September 1, 1998Assignee: Cirrus ABInventors: Per Erik Gustafsson, Ulf Haggstam
