AMD DS42585Underfilled Stacked Memory Package
(73-Ball Fine-Pitch Grid Array 8 x 11 mm; 0.80 mm pitch)
Contains an AMD/Fujitsu 4 Mbyte Flash die and a Samsung 1 Mbyte SRAM Die
• The AMD/Fujitsu die is on bottom, and measures 10.00 x 4.82 mm
• The Samsung SRAM die measures 8.07 x 5.32 mm• For more info, see

Fujitsu MB84VD23280FAUnderfilled Stacked Memory Package
(65-ball plastic FBGA; 0.80 mm pitch)
Contains an AMD/Fujitsu 8 Mbyte Flash die and a NEC 1 Mbyte FCRAM Die
• The AMD/Fujitsu die is on bottom; measures 7.72 x 6.86 mm• The NEC FCRAM die measures 8.00 x 4.53 mm• For more info, see
http://edevice.fujitsu.com/fj/DATASHEET/e-ds/e550221.pdf
Stacked packages that combine Flash and SRAM are common place in today’s cellular phones. Some of the components combine ICs from different fabricators as exemplified by these two memory products from AMD and Fujitsu. Notice that the components noted below, as well as the large BGA to their left, are underfilled with a clear material. Approximately 30% of the relatively large fine-pitch BGA components Portelligent sees are underfilled.

Many vendors are starting to offer small, commodity ICs in a simple WL-CSP formats, as exemplified by this EEPROM part from Atmel. Given the small size of these components, underfilling is deemed unnecessary.

ACF Adhesive Film
ACF Flip Chip has been used for several years as an attachment method for Chip-On-Glass (e.g. attaching display drivers to displays. It is now starting to be used in other applications – such as this flex circuit – that would otherwise have used a packaged IC or a Tape-Automated Bonded (TAB) IC.
One of the inherent attributes of ACF flip chip bonding is the ACF underfills the bonded device. The bead of material seen around the bottom edge of the chip is a result of the material being squeezed out during the thermocompressionbonding process.

Nokia 8310900/1800 MHz GSM Phone
• All ICs except one are packaged into various area array packages.
• The phone functions of the 8310 performed by 4 ICs:
1. Nokia GSM Transceiver
2. AMD Flash Memory
3. TI Baseband Processor
4. STMicroelectronics Power Mgmt
• All phones have some amount of SRAM memory, but this 8310 had no separate device present, so it is assumed the SRAM is integrated into one of the ASICs

The Mitsubishi D2101VAn Outlier or an Example of Phones to Come?
Released by NTT DoCoMo in March 2002, the D2101V is a continuation of the FOMA handset line and the first to use i-motion video-clip and music transmission service with a videophone. The 3G phone features a single, fixed digital camera that allows viewing from two directions: one for real time videoconferencing and the other for taking photographs or making videos. The phone also features a large 132x162-pixel color display and has a data transfer rate of 384Kbps (packet transmission) or 64Kbps for videophone calls.

Mitsubishi D2101V“Extreme” IC Packaging Techniques
• Dual Chip BGA Package assembled with Adhesive Flip Chip– The first use of adhesive flip chip bonding of a large processor type
IC that was made even more notable by having two chips bonded on both sides of a substrate. Also notable was that the chips were extraordinarily thin.
• Stacked Processor ICs– Stacked memory chips (e.g. combinations of Flash and SRAM)
have become common place; but this is the first observed instance of two large processor ICs being stacked.
• Multi-Chip Modules– Two custom (hybrid) components in the form of fine-pitched BGAs.

Two chips assembled by adhesive flip chip on both sides of 6 layer, build-up substrate. Chip thicknesses were 0.15 mm on bottom side and 0.20 mm on top. The stacked package wasunderfilled at the package perimeter after surface mount.
