对机械元件和辅助性电子元件进行微集成的能力,使得微机电系统(MEMS)成为了一项在众多领域得到应用的关键技术。人们对此产生了极大的兴趣。3-D MEMS器件的制造当然得益于半导体行业中所使用的相同的设备和标准化的工艺。


SET FC150自动器件接合机展示出了处理精密器件(小于200微米)的卓越能力,它使用真空吸盘,并且其对准精度小于±1微米。
MEMS器件,比如自适应光学系统或高端喷墨打印机头,均已能够用SET的倒装焊机(Flip-Chip Bonder)实现完美封装。





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...
