EP 23218 ABEL

Automated Back-End European Line
Summary

The current state of the art for silicon packaging is to use automatic stand alone machines for each process step. Driven by a better customer service and manufacturing optimisation, a partial integration of a few processes steps is proposed by some back-end equipment and manufacturers. The goal of ABEL is to achieve a complete automated and CAM controlled back-end line (Die and wire bounders, moulding, dambar cutting and laser marking systems, trim and form machine).


Objectives

  • To develop the hardware interfaces and software tools which are needed for integration of a fully automatic back-end line, with a particular emphasis on scheduling, flexibility, traceability, SPC, equipment data logging.

  • To improve the stand alone equipment reliability (up-time) and calibration tools to the level necessary for a successful line integration.

  • The processes and materials will be developed to meet the short cycle time of the automated line concept.

  • To develop tools for process control and auto-correction of critical process parameters.

EP 26245 ESCHETA

European Sources of Chip Scale Packages for Harsh Environment, Telecom & Automotive
Summary

The project targets the development, qualification and industrialisation of different European Chip Scale Package (CSP) sources with respect to their applicability in various environmental conditions such as telecom and automotive (Harsh Environment).

Three distinct approaches of chip scale package type constructions based on wafer level, flexible tape and rigid carrier redistribution will be followed, capable to meet ball pitches from 1.0 mm down to 0.5 mm depending on the application’s needs. The developed packages will be characterised by simulation and fully qualified under conditions required for telecom and automotive applications. In addition to single chip package long-term reliability, industrialisation processes such as solder joint reliability, surface mount assembly compatibility, PCB layout & design rules, repair & rework are addressed. In parallel, the developed European CSP approaches will be benchmarked, in the same application contexts, against commercially available CSP packages.

The applicability and industrialisation of the CSPs will be validated by means of two demonstrators covering the automotive volume market for harsh environment and complex telecom systems with high power requirements.



Objectives

  • to develop and establish various CSPs which will be provided by European sources.

  • to qualify the CSPs for usage under telecom and automotive conditions.

  • to validate the feasibility and manufacturability in a standard SMT process by setting up fully functional demonstrators for automotive and telecom switching (high power) application.

EP 26261 LAP

Low cost Large Area Panel Processing of

MCM-D substrates and packages
Summary

The main LAP objective is the development and demonstration of low cost high-density substrate manufacturing technology for first level die assemblies.

The cost target for high volume production of this high density interconnect substrates is as low as 1 US$/in² and shall be obtained by increasing panel size of today to panel areas up to 24 x 24 in² - the maximum practical panel size of today. While this largest thinkable panel size will probably remain an object of studies and experiments, 8 in , 12 x 12 in², and 16 x 16 in² are candidates for HDI production in the year 2000.

The substrate technologies developed will allow for a wide range of packaging options from inserted substrates into transfer-molded packages to integrated MCM-L/D and MCM-M/D (M=metal) area array packages. The suitability of the LAP technology will be demonstrated with three products from the communication, instrumentation and telecommunication sectors.


Objectives

  • High density / low cost substrate technology (capable for interconnecting 1000 I/O /in² by use of standard 1st level assembly processes) with a production cost target of 1US$ / in².

  • Development of a high performance MCM-D technology with 50 µm line pitch and 50 µm via/land to be verified by prototyping (cost will definitely be higher than 1US$/in²).

  • Verification of the technical target by prototyping on a LAP pilot line and verification of the cost target by appropriate cost modelling for a high volume production facility.

  • Qualification of the LAP technologies for semiconductor assembly into QFP and BGA.

  • Compatibility of the LAP technologies of the three manufacturers within a specified range of design rules and qualification requirements (to be specified during the project).

  • Verification of the LAP technologies developed by three product demonstrators.

Summary

GaAs technology for both discrete and IC components has proved to be indispensable for advanced telecommunication and automotive systems. The use of GaAs clearly starts where the silicon ends i.e. in meeting system requirements such as the RF front-end of mobile communication equipment, broadband radio links and anti-collision systems.

The main interest of this project is to develop and qualify semi-insulating bulk GaAs and epitaxial material for three major microwave applications: MESFETs, pseudomorphic HEMTs and GaInP-HBTs; and to establish competitive European production facilities in those domains.
Objectives


  • Establishing a reliable European source for 4" semi-insulating GaAs substrate fabrication, optimised for ion implantation applications. Comparison of 3" and 4" state-of-the-art world market material.

  • Epi-ready wafers directly usable for an MBE process. Attention will be paid to the requirements on geometry and surface conditions.

  • Production and qualification of high performance 4" MBE-grown P-HEMT epiwafers. Tests will be performed by a device supplier (SIE) to evaluate the material quality.

  • Comparison of the P-HEMT structures grown by MOVPE and MBE processes. In addition, application and quality as factors in production will be addressed.

  • Establishing a European commercial source of GaInP/GaAs HBT epitaxial wafers. Evaluation and characterisation of materials developed by EPI and IAF by the industrial users in their standard production lines.
