Abstract: A method is described for forming a high contact resistance region within the drain region or source region of an insulated gate field effect transistor as part of a high resistance resistor for electrostatic discharge protection of the field effect transistor. The silicide free contact region is formed as part of a self aligned silicide, or salicide, contact process. Nitrogen ion implantation followed by annealing is used to form a silicon nitride mask at the silicide free contact region. The mask prevents the formation of low contact resistance metal silicide at the silicide free contact region during the salicide process. Low resistance contacts to the gate electrode, source, and drain are formed using metal silicide.

Abstract: A SRAM cell with cross-coupled transistors, a pair of transfer gate transistors and a pair of load resistors is manufactured by forming a plurality of field effect transistors in a silicon substrate. In one embodiment, the transistors are formed in an SOI substrate to improve soft-error resistance.

A highly resistive layer is patterned to substantially cover and in contact with some selected contact hole openings and device contact areas. A conductive material is deposited into all of the contact hole openings so as to substantially over-fill the contact hole openings and make electrical contact with the device contacts and patterned resistive layer.

Abstract: A method of fabricating a polycrystalline silicon thin-film transistor having two symmetrical lateral resistors is disclosed. Two sub-gates are formed along with a gate in the gate metal or polysilicon layer of the thin-film transistor. The two sub-gates that are located symmetrically on the two sides of the gate have equal distances to the gate. One sub-gate is near the drain of the thin film transistor and the other near the source. Two sections in the polycrystalline silicon layer of the thin film transistor are blocked by the two sub-gates and no impurity material is doped. The two undoped sections form the symmetrical lateral resistors of this invention. The lateral resistor near the drain decreases the electric field in the nearby depletion area when the thin-film transistor is switched off. The current leakage is reduced.

Abstract: In the present invention, a first protective layer formed over a diaphragm is prevented from being etched unnecessarily at the time of etching a second protective layer, and the detection accuracy of the diaphragm is improved.In a process for producing a semiconductor pressure sensor, a first protective layer 4, a metal layer 8 and a second protective layer 6 are successively formed by deposition over a diaphragm 1a, and the second protective layer 6 is removed by etching so that the second protective layer 6 is left on a predetermined portion of an electrode 5. Since the metal layer 8 acts as an etching stopper layer at the time of removing the second protective layer 6 by etching, the first protective layer 4 over the diaphragm 1a is prevented from being etched. The metal layer 8 is removed by etching thereafter so that only the first protective layer 4 is formed over the diaphragm 1a.

Thus, a capacitor having small change in capacitance versus applied voltage is manufactured in a MOS IC device having a polycide gate.
