Hanxin

Hanxin (simplified Chinese: 汉芯; traditional Chinese: 漢芯; pinyin: Hànxīn) was an notorious Chinese academic fraudulence case, committed in the name of a digital signal processing (DSP) microchip. Chen Jin, a professor at Shanghai Jiao Tong University claimed to have developed the chip in 2003. The Hanxin 1 was reportedly the first DSP chip to have been wholly developed in China. However, the chip was later revealed to have been developed by Freescale Semiconductors, a former Motorola subsidiary, with the original identifications sandpapered away.

According to analysts, the case underscores the pressure on Chinese researchers to develop technological innovations which would enable China to bridge the gap with the West. The Hanxin scandal was viewed as a major setback to China's ambition in terms of losses of substantial public funds and the time in a race that China entered late.
