多芯片组件以及液晶显示

在实现多芯片组件(MCM)、III-V族器件以及液晶显示器的高精度对准方面,SET的倒装焊机(flip-chip bonder)的多功能性已被证明是其宝贵的财富。

通过采用目前的倒装芯片技术,标准的MCM应用,比如汽车电子和电脑,以及手表、电话和其它读出显示器上的LCD/GOS(玻璃上芯片)应用,已经得到了大幅完善。

接合工艺

诸如灵活的用户界面、自动对准能力以及自动工具交换等功能,最大限度地实现了高端倒装芯片接合应用的便捷性。
SET的倒装焊机(flip-chip bonder)具有混合处理的能力,可以在同一个周期内进行多个接合处理。这为同一周期内具有不同尺寸芯片的多芯片环境,提供了实施倒装芯片接合的无与伦比的灵活性。

Process and Equipment Enhancements for C2W bonding in a 3D Integration Scheme

This paper will review three major areas of process or equipment development surrounding the above problems, namely the issue of throughput enhancement by using a sacrificial adhesive to temporarily tack the dice before collective bonding, the issue of prior or in-situ removal and prevention of surface oxides at the bonding interface, and the issue of local environmental control to reduce particulates and other airborne contaminants. Each of these 3 will be explored with hardware solutions proposed, along with process results on test vehicles or functional devices.

Chip-to-Wafer Technologies for High Density 3D Integration

CEA-Leti partnering with SET, STMicroelectronics, ALES and CNRS-CEMES on advanced Chip-to-Wafer technologies for 3D Integration in the frame of the PROCEED project, a 4.2 Million Euros, 24 months project supported by French FIU (Fond Interministeriel Unique). Started in 2009, the goal of the PROCEED project is to demonstrate high alignment accuracy (<1µm) of chip-to-wafer structures made by direct metallic bonding.

3D-IC Integration using D2C or D2W Alignment Schemes together with Local Oxide Reduction

3-Dimensional interconnection of high density integrated circuits enables building devices with greater functionality with higher performances in a smaller space. This paper explores the chip-to-chip and chip-to-wafer alignment and the associated bonding techniques such as in-situ reflow or thermocompression with a local oxide reduction which contributes to higher yield together with reduction of the force or temperature requirements.

Flip-chip die bonding: an enabling technology for 3D integration

3-Dimensional Integration of Integrated Circuits is a method to build greater functionality into ever-smaller spaces for electronic circuitry, wherein dice of varying sizes, materials, or even application types are electrically and mechanically bonded together.

Die-to-wafer bonding of thin dies using a 2-step approach: high accuracy placement, then gang bonding

25 um thick dies, mounted on thick carrier die, were placed on a 300mm landing wafer using the High Accuracy Die Bonder SET-FC300. The bonding process was either Cu/Cu or Cu/Sn with respective pitch of 108 µm and 408 µm...
