Title: Pseudo-random generator and check sum circuitry for vlsi chip
IPC: G01R31/3181
Filed: 1988-09-30
Abstract: A standard pseudo-random number generator 
comprises a shift register with a plurality of XOR 
feedback paths from the last stage to the first and 
selected intermediate stages. This invention provides 
a larger generator by concatenating four such registers 
9a to 9d in series. The feedback pattern of each 
register is a maximum length polynomial, and the 
registers are all of different lengths (67, 63, 64, and 
65 bits) such that their periods are all coprime. The 
largest register is first for maximum randomness.  
     The number of feedback paths of each register is an 
even integer approximately equal to either one third or 
two thirds of the number of stages in the register.  
     The generator may be used in a VLSI chip including a 
core logic area performing an operational function to 
apply a test pattern to the core logic. For receiving 
the output of the core logic in response to the test 
patterns, the chip may include an check sum output 
register 8 in the form of a cyclic ring with an initial, 
relatively small portion in the form of a linear feed­
back shift register. The generator and check sum 
output may form part of test circuitry in a VLSI chip, 
being configured partly from I/0 cells and partly from 
dummy cells, the I/0 cells normally operating as input 
and output to the core logic of the chip.

Title: Integrated terahertz electromagnetic wave system
IPC: H04B10/118
Filed: 1989-05-22
Abstract: A communication system for transmitting and receiving 
terahertz signals has a emitter employing a resonant 
radiating antenna (5) connected to an ultrafast 
switch (6). The switch (6) is a subpicosecond photo­
conducting switch coupled to a coplanar transmission

Title: Transfer circuit for signal lines
IPC: H03K17/04
Filed: 1989-01-05
Abstract: A transfer circuit for signal lines comprises a 
bipolar transistor (QB₁₁) and two MIS transistors (e.g. QP₄₁ , QN₄₃). A base of 
the bipolar transistor is connected to a first line(DB₁) of 
the signal lines, a collector of the bipolar transistor 
is connected to a power source (V CC ), the two MIS transistors 
are connected in series, the connected point is 
connected to an emitter of the bipolar transistor (QB₁₁), and 
one end of the series-connected MIS transistors is 
connected to the first line (DB₁) and the other end is con­
nected to a second line (DB) of the signal lines. When data on the 
first line (DB₁) is transferred to the second line (DB) , the MIS 
transistor (QP₄₁) connected between the base and emitter of the 
bipolar transistor (QB₁₁) is made non-conductive and the other 
MIS transistor (QN₄₃) connected to the second line(DB) is made 
conductive. The transfer circuit constituted as above 
can carry out data transfer of the signal lines at a high 
speed by rapidly charging the second line (DB).

Title: Semiconductor integrated circuit chip-to-chip interconnection scheme
IPC: H01L23/14
Filed: 1989-07-13
Abstract: Integrated circuit chip-to-chip interconnections are made via gold pads 
(24, 34) on each chip (101, 102) that are bonded to corresponding gold pads (14, 
12) on a silicon wafer chip carrier (10). The pads on the chips and/or the pads on 
the carrier are characterized by texturing (roughening) with a feature size of the 
order of a micrometer or less, so that each of the pads on the chip can be attached 
to each of the pads on the carrier by compression bonding at room temperature-- 
i.e., cold-well bonding. In particular, the texturing of the gold pads on the silicon 
carrier is obtained by etching V-grooves locally on the surface of the underlying 
silicon carrier in the regions of the pads, thermally growing a silicon dioxide layer 
on the silicon carrier, and depositing the gold on the silicon dioxide layer.

Patent EP-0373830-A3 (EP)
Title: Floating gate transistor
IPC: G11C16/04
Filed: 1989-12-08
Abstract: A floating gate transistor is programmed by a 
conventional charge pump providing drain programming 
current, typically held below about 1 µA. The drain 
current can be limited by connecting a resistor between 
the source and ground, or by limiting the transistor 
control gate voltage. Instead, a charge pump is 
coupled to the drain while the control gate is 
repetitively pulsed. Each time the control gate is 
pulsed, the transistor turns on, and although the drain 
is initially discharged through the transistor, some 
hot electrons are accelerated onto the floating gate, 
and eventually the floating gate is programmed. The 
erase gate voltage may be raised to enhance programming 
efficiency.
