Justem Co., Ltd.
Capable of acting as customers’ “Technology Development Department” for semiconductors in all stages from experimentation to mass production
We develop, manufacture, and sell various production machines including equipment for inspection, measurement, manufacturing, rationalization and energy saving, mainly for customers in the semiconductor industry. We excel in clean, energy saving, high speed, high precision, automation technologies. We also have expertise in inspection with image processing technologies and measuring of thickness and shape. Our clients include many major corporations in Japan, such as Shin-Etsu Chemical, DENSO, and Toyota Motor. We have also developed a Floating Thickness Measuring (FTM) prototype for next generation large diameter silicon wafers with the Industrial Research Institute of Niigata.
[Product description] Laser or electrostatic capacitive sensors are able to make non-contact measurement of Si or other non-transparent wafers. However these conventional sensors had difficulties in non-contact measurement of SiC , GaN, sapphire, or other transparent or semi-transparent wafers. Our TME-F02 makes it possible to make non-contact measurement of transparent and semi-transparent wafer bodies with our integrated automation technologies. We are pleased to offer proposals from the development phase to the mass production phase. For detailed information and movie clips of our equipment, please contact our Sales department. [Major facilities and equipment] Demonstration Unit TME-F02
[Product description] This is standard equipment we provide, among many other Si wafer non-contact thickness measuring devices. We offer this product with absolute confidence for its ease-of-use on site, high quality, and cost performance. A single unit of this product can measure Φ4” 5” 6” and 8” Si wafers, which necessitate no machines made by others. For detailed information and movie clips of our equipment, please contact our Sales department.

[Major facilities and equipment] SiC wafer thickness measurement demonstration can be performed on TME-F01 or TME-F02.
[Product description] We extend our offer of technologies for devices used in the semiconductor industry to the food industry! This product is clean, energy efficient, easy to maintain, and operable through simple touch panels... which simplifies sales management as well! Only we offer a 9.6m masterpiece, in lots of 111! We also provide smaller lots for limited installation space. This is useful in advertising Japan’s locally brewed sake and introducing Japanese sake to overseas visitors who will be visiting Japan for the Olympics. We are eager to contribute to sharing Japanese food culture with the rest of the world. For detailed information and movie clips of our equipment, please contact our Sales department.
[Product description] This offers high-speed tray to tray conveyance with no damage. Using image processing technology, it confirms the state of semiconductor chip retention and tray shape before conveyance. Storage will be done without rubbing the tray sides or semiconductor chip edge. We have absolute confidence in this product for its ease-of-use on site, quality, and cost performance. We will also propose the most suitable equipment for your production site. For detailed information and movie clips of our equipment, please contact our Sales department.
