The Evolution of Transistor Technology
The journey of transistor technology started with the invention of the monolithic IC chip and the MOS transistor in 1959. These breakthroughs opened the door to the miniaturization of electronic components and devices. Harvey C. Nathanson’s resonant gate transistor, created in 1965, was an early MEMS device.
In the 1980s, the focus on miniaturized electronics grew, with mass production starting in the 1990s. Today, we have tiny, powerful devices like MEMS gyroscopes in smartphones. These devices are incredibly small, weighing less than a milligram and the size of a grain of sand.
Advances in Semiconductor Technology
The bulk FinFET has been a key technology from the 22 nm to 10 nm node. It’s expected to reach the 5 nm node. However, reaching the 3 nm node poses significant challenges.
New technologies like fin-on-insulator (FOI) FinFET and nanowire (NW) FETs are being explored. They aim to improve short channel effects (SCEs) and leakage control. Stacked gate-all-around (GAA) NW or nano-sheet structures are seen as promising for the 3 nm node.
The Shift towards Miniaturization
As devices get smaller, challenges in CMOS design grow. There’s a need for low power and voltage variations. Smaller transistors require more current and higher frequencies. Shorter channels also lead to higher leakage.
Lithography for nano-scaled transistors has evolved. 193 nm ArF immersion with multiple patterning is used for the 20-nm and 14-nm nodes. For the 7-nm node, extreme ultraviolet (EUV) lithography and 193 nm immersion with multi-patterning are considered. Quad-patterning or double-patterning might be used, depending on cost and tool availability.
“The shift towards miniaturization accelerated in the 1980s, with mass manufacturing beginning in the 1990s.”
