China's progress in advanced semiconductor technology slows

SHANGHAI -- China is facing delays in miniaturizing semiconductors. In a Nikkei survey, most of the seven major Chinese semiconductor manufacturing equipment makers that responded said their mainstay products were those for making 14 nanometer to 28 nm chips, which are two or three generations behind the world's advanced chips. Some said even older generation machines were their main products.

Many of the respondents said U.S. sanctions against China had hindered their procurement of parts and materials from abroad. They also said using domestic parts and materials in place of items from overseas had resulted in lower yield rates.
