  • Patent number: 11855137
    Abstract: This disclosure provides for robust isolation across the SOI structure. In contrast to forming a charge trap layer in specific areas on the structure, a charge trap layer may be built across the insulating/substrate interface. The charge trap layer may be an implantation layer formed throughout and below the insulation layer. Devices built on this SOI structure have reduced cross-talk between the devices. Due to the uniform structure, isolation is robust across the structure and not confined to certain areas. Additionally, deep trench implantation is not required to form the structure, eliminating cost. The semiconductor-on-insulator substrate may include an active silicon layer over an oxide layer. The oxide layer may be over a charge trap layer. The charge trap layer may be over a silicon substrate.

Each data storage device is capable of operating in one of (N+1) power saving functions where N is an integer larger than 1. The (N+1) power saving functions sequentially correspond to from the 0th to the Nth power saving levels. The controller reads a user-setting power saving level (I) where I is an integer index ranging from 0 to N. The controller reads a current power saving level (J) of a current power saving function of one of the plurality of data storage devices where J is an integer index ranging from 0 to N. The controller controls said one data storage device to operate in one power saving function among the (N+1) power saving functions according to the user-setting power saving level (I) and the current power saving level (J).

  • Publication number: 20230389436
    Abstract: An ultra-large height top electrode for MRAM is achieved by employing a novel thin metal/thick dielectric/thick metal hybrid hard mask stack. Etching parameters are chosen to etch the dielectric quickly but to have an extremely low etch rate on the metals above and underneath. Because of the protection of the large thickness of the dielectric layer, the ultra-large height metal hard mask is etched with high integrity, eventually making a large height top electrode possible.

  • Patent number: 11817345
    Abstract: Semiconductor-on-insulator (SOI) field effect transistors (FETs) including body regions having different thicknesses may be formed on an SOI substrate by selectively thinning a region of a top semiconductor layer while preventing thinning of an additional region of the top semiconductor layer. An oxidation process or an etch process may be used to thin the region of the top semiconductor layer, and a patterned oxidation barrier mask or an etch mask may be used to prevent oxidation or etching of the additional portion of the top semiconductor layer. Shallow trench isolation structures may be formed prior to, or after, the selective thinning processing steps. FETs having different depletion region configurations may be formed using the multiple thicknesses of the patterned portions of the top semiconductor layer. For example, partially depleted SOT FETs and fully depleted SOI FETs may be provided.
