چکیده

Will computers that see and understand what they see revolutionize industry by automating the part orientation and part inspection processes? There are tw o obstacles: the expense of computing and our feeble understanding of images . We believe these obstacles are fast ending. To illustrate what can be done we describe a working program that visually determines the position and orientation of silicon chips used in integrated circuits. Work reported herein was conducted at the Artificial Intelligence Laboratory, a Massachusetts Institute of Technology research program supported in part by th e Advanced Research Projects Agency of the Department of Defense and monitored by the Office of Naval Research under Contract number N00014-70-A-0362-0005 ORIENTING SILICON INTEGRATED CIRCUIT CHIPS FOR LEAD BONDIN G by

Active Test Chips for in Situ Wire Bonding Process Characterisation

The real-time monitoring of an industrial ball bonding process is reported using a new type of test chips with custom-made integrated sensors (microsensors). These sensors were fabricated using a commercial double-metal CMOS process [1]. Two types of integrated monitors are reported, a temperature [2] and an ultrasound shear force sensor [3]. The temperature sensor uses the thermoelectric prope...

Laser-Assisted Bumping for Flip Chip Assembly

A novel laser-assisted chip bumping technique is presented in which bumps are fabricated on a carrier and subsequently transferred onto silicon chips by a laser-driven release process. Copper bumps with gold bonding layers and intermediate nickel barriers are fabricated on quartz wafers with pre-deposited polyimide layers, using UV lithography and electroplating. The bumps are thermosonically b...

Characterizations of Rapid Sintered Nanosilver Joint for Attaching Power Chips

Sintering of nanosilver paste has been extensively studied as a lead-free die-attach solution for bonding semiconductor power chips, such as the power insulated gated bipolar transistor (IGBT). However, for the traditional method of bonding IGBT chips, an external pressure of a few MPa is reported necessary for the sintering time of ~1 h. In order to shorten the processing duration time, we dev...

Flip Chip Joining on FR-4 Substrate Using ACFs

Anisotropic conductive adhesive films (ACF) were used to attach daisy-chained test chips on FR4 substrates. The feasibility of ACF joining was studied since it is a potential method for fine-pitch bare-die attachment on low-cost organic substrates. Four types of test chips were used, each having a pitch of different size. One of the chips had an area array structure, one had a staggered structu...

Injection molded microfluidic chips featuring integrated interconnects.

An injection molding process for the fabrication of disposable plastic microfluidic chips with a cycle time of 2 min has been designed, developed, and implemented. Of the sixteen commercially available grades of cyclo-olefin copolymer (COC) that were screened for autofluorescence and transparency to ultraviolet (UV) light, Topas 8007 x 10 was identified as the most suitable for production. A ro...
