Title: Improved method for etching vias
Inventor: JOHNSON DAVID J
IPC: H01L21/3065
Filed: 2003-04-03
Granted: 2007-03-21
Abstract: An improved method for etching a substrate that reduces the formation of pillars is provided by the present invention.

Title: Communication interface for diagnostic circuits of an integrated circuit
Inventor: KIMELMAN PAUL
IPC: G06F13/42
Filed: 2003-11-04
Granted: 2007-08-11
Abstract: An integrated circuit is provided with diagnostic circuitry, such as serial scan chains or debug bus access circuits, with which communication is established using an interface circuit coupled with a bi-directional serial link to an external diagnostic device. The bi-directional serial link carries both data and control signals. The serial protocol can include provision for a pacing signal whereby the diagnostic circuitry can indicate to the external diagnostic device when it is ready to receive more data and/or when it has completed a particular diagnostic operation. This self-pacing ability is strongly advantageous. A training signal generated by the external diagnostic device may be detected by the interface circuit on initialisation and used to derive sampling point timings. Thus, the need to provide a separate clock signal can in such circumstances be avoided.

Title: Device for punching green sheets
Inventor: HALAMODA HANS-JOACHIM
IPC: B28B11/00
Filed: 2004-01-09
Granted: 2006-01-11
Abstract: A punching tool for green sheets or similar sheetlike workpieces has a support plate, with punched holes (7) embodied in it, and a holding-down plate, which is disposed above the support plate and in which holding-down openings (24) are embodied. Dies (8) extend with their operative portions (23) through the stripper openings (24) and are guided in them. The operative portions (23) are embodied in graduated form. They have a punching portion (26) of reduced diameter. The length of each punching portion (26) is less than the length of the stripper opening (24). When the die (8) is at its top dead center, the punching portion (26) is located entirely in the stripper opening (24). Moreover, a fragment of the portion (25) that belongs to the operative portion (23) protrudes into the stripper opening (24), in order to guide the die (8). The punching portion (26) is only approximately as long as required for the punching stroke of the die (8). Its length preferably matches the length of the punching stroke. The slight length of the punching portion (26) makes an especially slender embodiment of the punching portion possible, thus making it possible to create especially small punched holes.
