Elemental Technology

Elemental Technologies Supporting Products

Aiming to further develop its core probing technology to create products that meet needs at the leading edge, MJC is focusing on R&D into elemental technologies, including technologies for electronic measuring, precision machines, materials, and MEMS.

Electronic Measuring Technology

To further improve its electronic measuring technology, MJC is working on the development of new technologies that can achieve the best performance at appropriate prices.

MJC is developing elemental technologies in line with the advancement of probing technologies. In the area of probe cards, MJC focuses on responding to the higher density and miniaturization of devices and high speed, high frequency and greater capacity of signal transmission. In the area of wafer probers, MJC aims to push these probe card characteristics as far as possible.

Precision Machine Technology

Smaller, higher-density electronic devices require a high-rigidity stage, accurate positioning technology, and countermeasures against thermal deformation of mechanical components wafer probers.

In order to enable needles to contact electrodes with several decade micron-sized sides at micron-level accuracy, control technology for highly precise and high speed positioning of the stage and device-handling technology are needed. Meanwhile, the one-touchdown test, which puts a tremendous load on wafers, requires a highly rigid stage. Meanwhile, for in-car devices, the range of measurement temperatures are expanding year by year so that reducing thermal deformation of the mechanical component is becoming crucial.

In response to these diversifying test requirements, MJC is striving to improve precision machine technology combined with elemental technologies and to propose efficient testing environments, such as by reducing running costs and reducing the time required for testing.

Material Development for the Future

To respond to new needs with an eye toward the future and achieve better product characteristics, MJC is constantly researching and developing technologies for mastering new materials. MJC evaluates materials through experimentation and verification of their electrical and mechanical characteristics and optimizes the characteristics to improve product quality and performance.

MJC makes such R&D efforts jointly with material manufacturers and universities, and applies its R&D results, namely, new materials including alloy, plating solution and plastic, to its products. This is part of MJC's commitment to basic research for the future.

Unique MEMS Technology Responding to the Need for Miniaturization

In the area of semiconductors, increasing miniaturization of LSI requires accuracy at the level of the micron (one thousandth of a millimeter) for contacts of input/output terminals.
MJC is pursuing microelectromechanical system (MEMS) technology via its own unique method in order to develop products able to fully exploit its creative probing technology.

Use of Simulation Evaluation

Key factors that influence the performance of electronic measuring instruments include electrical characteristics and mechanical characteristics. To shape these characteristics, MJC uses computer simulation evaluation, which enables it to minimize the number of prototypes and therefore ensure its products achieve a higher degree of perfection within a short period of time.
