Title: Circuit managing numbers of accesses to logic resources
Inventor: MAJOS JACQUES
IPC: G06F12/00
Filed: 1992-03-27
Granted: 1996-04-30
Abstract: A circuit managing numbers of accesses to logic resources, such as buffer memory data cells in a time switching system. The circuit is structured around a counting cell matrix.  Each counting  cell  includes  a  synchronous  counter  storing  an instananeous number of accesses relating to a corresponding data cell of the buffer memory.  This encoded access number is representative of the number of outgoing multiplex ways from the  system to which a data  block received on  an  incoming multiplex way in the system must still be diffused. A given circuit operating cycle includes the loading of a counter by an access  number  corresponding  to  a  free  data  cell  address, supplied by matrix column and row encoders during a  cycle preceding  the  given  cycle.    This  loading is  obtained  by selecting a column and row by cell-to-be-charged column and row decoders, and by applying the encoded access number to an input bus of the counters in the cells. Simultaneous to loading, an updated encoded number of a counter in a second matrix cell is decremented by one unity in response to the read-out address applied  to  cell-to-be-decremented  address  column  and  row decoders  when  the  buffer  memory  cell  corresponding  to  the second cell is being read.

Title: Direct thermocompression bonding for thin electronic power chips
Inventor: NEUGEBAUER CONSTANTINE ALOIS
IPC: H01L21/603
Filed: 1991-10-24
Granted: 2002-05-14
Abstract: Annealed copper foil (12) is coated with chromium film (16), followed by coating with an appropriate thickness of gold film (14) and is thermocompression bonded to an aluminum metallized substrate (18) on a silicon chip (30) to provide solderable, high current contacts to the chip. The foil is formed into appropriate electrical network-contact patterns (40) and is bonded to the silicon chip only where aluminum metallization exists on the chip. Leaf (wing) portions (46) of the foil extend beyond the bound-aries of the silicon chip for subsequent retroflexing over the foil to provide electrical contact at predesignated locations (49). Ex-ternal contacts to the foil are made by penetrating through a ceramic lid positioned directly above the foil area. Thus, direct ther-mocompression bonding of a principally copper foil to aluminum semiconductor pads can replace current gold detent/pump connections by securing a copper conductor to a silicon chip through an intermetallic AuAl2 link and an aluminum stratum.
