Latest Patents

One of Asaka's latest patents is a method for manufacturing semiconductor integrated circuit devices. This method aims to prevent breakage and separation of wiring in devices such as the bit-line of a DRAM. The process involves depositing a high-density plasma silicon oxide film on wirings using a high-density plasma CVD technique at a first temperature. The structure is then subjected to rapid thermal annealing (RTA) at a second temperature, which is higher than the first. Via holes are formed in the silicon oxide film, and conductive films are created, ensuring that the first conductive film is formed at a lower temperature. This innovative approach reduces film stress and prevents breakage of the bit-line during heat treatment.
