This makes trench capacitors suitable for constructing embedded DRAM (eDRAM) (Jacob, p. 357). Disadvantages of trench capacitors are difficulties in reliably constructing the capacitor's structures within deep holes and in connecting the capacitor to the access transistor's drain terminal (Kenner, p. 44).
in DRAM memory circuits, capacitor trenches may be 10–20 μm deep, in MEMS, DRIE is used for anything from a few micrometers to 0.5 mm. in irregular chip dicing, DRIE is used with a novel hybrid soft/hard mask to achieve sub-millimeter etching to dice silicon dies into lego-like pieces with irregular shapes.

The two main types of random-access memory (RAM) are static RAM (SRAM), which uses several transistors per memory cell, and dynamic RAM (DRAM), which uses a transistor and a MOS capacitor per cell. Non-volatile memory (such as EPROM, EEPROM and flash memory) uses floating-gate memory cells, which consist of a single floating-gate transistor per ...
The two most common types of DRAM memory cells since the 1980s have been trench-capacitor cells and stacked-capacitor cells. [25] Trench-capacitor cells are where holes (trenches) are made in a silicon substrate, whose side walls are used as a memory cell, whereas stacked-capacitor cells are the earliest form of three-dimensional memory (3D ...
Ferroelectric RAM Magnetoresistive random-access memory nvSRAM BBSRAM Technique The basic storage element is a ferroelectric capacitor. The capacitor can be polarized up or down by applying an electric field [18] Similar to ferroelectric RAM, but the atoms align themselves in the direction of an external magnetic force. This effect is used to ...
DeLorean Motor Company [1] (also doing business as Classic DMC) is a US company based in Humble, Texas, established in 1995 by Liverpool-born mechanic Stephen Wynne, [2] using the branding of the defunct automobile manufacturer.

FuelPositive Corporation (formerly EEStor) [1] is a company based in Cedar Park, Texas, United States that claims to have developed a solid state polymer capacitor for electricity storage. [2] The company claims the device stores more energy than lithium-ion batteries at a lower cost than lead-acid batteries used in gasoline-powered cars.
