LSI / ASIC Design Services

TOPPAN has been providing LSI / ASIC development and design services over the past 40 years.
Its development experiences include wide variety of fields, such as analog, memory, LCD, LED drivers, and microcomputer logic.
As for development of RF and analog mixed signal in particular, TOPPAN prides itself on top class technical know-how in the industry with its accumulated technologies including power circuit, amplifier, high frequency LSI, and system LSI digital mixed macro.

We provide turnkey services of power semiconductors where it is difficult to secure wafer manufacturing capacity, for example automotive, industrial equipment, factory automation, and other applications.
In addition to total solution services from design to packaging and mass production, we can also undertake wafer manufacturing.
We also offer porting of wafer manufacturing processes owned by device manufacturers and contract services for partial processing.
Using this service enables a stable supply of a wide variety of small-lot products.

Color Filter Arrays

On-chip color filters (color filter arrays and micro-lens array) are essential for colorizing image input devices such as CMOS image sensors and small display devices such as OLEDoS, and are used in a wide range of applications including cameras for smartphone, automotive, security, and medical applications, as well as head mounted displays. Color filter of red, green and blue (RGB) as the primary colors of light or cyan, magenta, yellow and green (CMYG) as the complimentary colors is directly formed on each of the phototransistors generated on a silicon wafer.

TFT-LCD

The high value-added TFT-LCDs of the "ORTUS" brand called "Blanview" realizes high pixel count, high definition and low power consumption while enhancing outdoor visibility by using HAST® (Hyper Amorphous Silicon TFT) as its core technology, and is adopted for various equipment such as industrial equipment.

• a-Si TFT (TN/VA/IPS-FFS)
• Small-to-Medium size
• Sunlight readable and low power consumption technology "Blanview"
• Wide range of standard product lineup
• Industrial & Automotive appliciations

LC MAGIC is an ultra-thin liquid crystal film developed based on TOPPAN's liquid crystal technological achievements accumulated through our display-related businesses. The flip of a switch can transform the film state from transparent to opaque, or vise versa. This innovative product is used in a wide variety of applications, as an alternative to a blind or curtain, or as a digital signage screen. Our lineup is: Normal-Mode film that switches to transparent when power is turned on, and Reverse-Mode film that switches to transparent when power is turned off.
