Point wetting Technology（EWOD)
Based on the principle of Electrowetting, the digital microfluidic control technology can realize the free movement of liquid droplets of nano to microliter volume on the two-dimensional plane of the chip using only voltage signals. Meanwhile, the on-chip droplets are used as carriers, which can carry various reaction samples such as biochemical reagents, cells, proteins, DNA and RNA, and realize the movement, separation, fusion and redistribution of samples using computer programs; at the same time, it is matched with modular functional components (temperature control , Magnetic attraction, fluorescence detection, etc.) to meet the needs of various experiments.
Thin film electronics manufacturing technology
Thin film transistor (TFT)
The TFT thin film transistor is the basic circuit unit that composes the active digital microfluidic chip. It can control the on or off of the droplet driving electrode. It is also the basic structure of the chip row and column electrode scanning circuit. Currently, mature TFT technologies mainly include a-Si (amorphous silicon), LTPS (low temperature polysilicon), and IGZO (indium gallium zinc oxide). According to different chip characteristic requirements and manufacturing cost considerations, the corresponding TFT technology type can be selected reasonably.
Conventional chip is composed by stacking several functional layers (insulating film layers, metal film layers) to form a complex integrated circuit structure. Its realization relies on high-precision and mature semiconductor manufacturing processes. ACXEL's chip manufacturing process has extremely high compatibility with the manufacturing process of display backplanes in the FPD industry. Through the cooperative foundry model with display backplane manufacturers, with the help of mature large-scale TFT backplane mass production technology, combined with AOI automatic optical inspection and Laser Repair technology, we can achieve nearly 100% chip substrate yield.
