Patent EP-0160255-A2 (EP)
Inventor: VOSBURGH KIRBY GANNETT
IPC: H01L21/265
Filed: 1985-04-20
Abstract: A field effect transistor with a lightly doped drain and a heavily doped source is formed utilizing a single reactive ion etched silicon dioxide spacer. A gate electrode of polycrystalline silicon on a thin layer of silicon dioxide grown on a silicon substrate of one conductivity type is utilized in the formation of a pair of shallow, lightly doped regions of opposite conductivity type in the substrate on each side of the gate electrode. A pair of silicon dioxide spacers is provided, each on a respective side of the gate electrode and overlying a respective shallow, lightly doped region, by anisotropically etching a layer of silicon dioxide deposited over the structure. One of the spacers is masked and the other spacer is removed by reactive ion etching. Thereafter, a pair of deep, heavily doped regions of opposite conductivity type are formed in the substrate not masked by the gating electrode and the insulating space to complete the formation of the drain and source regions of the device.
