features
• The high-density wiring by the fine line and pattern
is available
• Miniaturization is possible by burying L, C and Strip-line
• By the uses of low dielectric-loss ceramics and low loss
conductors, the substrates excel in the high frequency
characteristic
• As the thermal expansion coefficient is close to silicon’s,
the substrates are suitable for the bare chip mounting
• By preparing the thermal vias under bare chips,
the substrates are excellent in the heat dissipation
• The substrates are outstanding in heat resistance
and humidity resistance due to the ceramics used

definition
With the high functioning and the advance
in down-sizing of electronic equipment,
wiring substrates are also required to
be highly functioned.
One of the technologies to respond to the
high functioning of the substrates is LTCC
(Low Temperature Co-fired Ceramics),
which is the ceramic multilayer technology
that enables the alumina to be fired at a
“low temperature” of 900°C or lower by
adding glass materials to the alumina
while it is fired by a “high temperature”
of about 1500°C.
It is the LTCC’s important characteristic
that low melting point materials like Ag,
etc. can be used for the buried conductors
for the low temperature firing.
