applications. Higher thermal performance can be achieved by
adding a heat spreader or heat sink to the die's exposed
backside. In addition, future die-up configurations will provide
a direct heat dissipation path into the product motherboard
through the die backside.

Amkor's etCSP package is the first ball grid array
capable of an extremely thin 0.5 mm maximum
mounted height. This package can squeeze into
applications requiring a thin form factor. The
®
etCSP package is constructed using conventional
Min
Max
IC processing including standard wire bonding,
molding and substrate infrastructure. The resulting
package consists of one or two peripheral rows of
0.3 mm diameter solder balls to allow common
SMT processing.

There are many advantages as a direct result of the
unique etCSP design. One key advantage is the
®
0.5 mm mounted height of the package, the result of
solder ball diameter and thin core laminate substrate.
Every other aspect of the package, die, wires and
moldcap are within the dimensions of the substrate

and solderballs. Another direct result of the etCSP
design is the superior moisture resistance. Since
die attach materials are not used to mount the
die, there is reduced capability to trap moisture.
Therefore, popcorn induced delamination is reduced.

The etCSP package can also be designed with the
capability of stacking completely tested packages,
i.e., packaged memory, into a single footprint on the
motherboard. In this manner, two stacked etCSP™
packages can be tested before mounting and the
combined height is less than 1.0 mm.
• First failure 1100 cycles
• Lead free solder
Applications:
®
Amkor's etCSP design makes this package type ideal for PCMCIA card applications, mini disk
drives, thin wireless handsets, Flash or EEPROM memory and other portable products where vertical
®
height is limited. Because of the unique design of the etCSP package, stacking is easily achieved
with proper substrate designs. This creates an opportunity to multiply memory capacity without
increasing board area.
