Latest Patents

One of Hongxue Liu's latest patents is titled "DFL Read Head with SiOx Cap Layer on AlOx Refill Layers". This invention relates to the development of a read head and methods for forming it. The process begins with the formation of a dual free layer (DFL) sensor and a rear hard bias (RHB) structure on a seed layer. The innovation lies in the use of a photoresist that allows for the deposition of a refill layer followed by a SiOx cap layer. This cap layer acts as a stop layer for the refill layer, ultimately contributing to the formation of a substantially flat topography in the finished read head.

Another significant patent is the "Two-Dimensional Magnetic Recording Reader with Dual Free Layer Magnetic Tunnel Junction". This invention focuses on a two-dimensional magnetic recording (TDMR) read head featuring a magnetic tunnel junction (MTJ). The structure includes a dual free layer (DFL) MTJ positioned between two shields, where a synthetic antiferromagnetic (SAF) soft bias structure and a rear hard bias (RHB) structure enhance the functionality of the reader. The innovative DFL MTJ design effectively increases the area density capacity, marking an important advancement in magnetic recording technology.
