摘要:
An insulated gate field effect transistor having a glass gate insulator is fabricated by diffusing into a semiconductor substrate the impurities required to produce the channel, source and drain, exposing the substrate by etching away any remaining masking layer, forming a gate insulator of thin film ion impermeable glass on the exposed substrate and then metalizing and packaging the resulting device. Advantageously, the thin glass film is also used as a passivating layer. IGFET''S fabricated in this manner are significantly more resistant to contamination than are prior art devices using oxide insulated gates and passivating layers. As a consequence they are more economical to fabricate and more reliable in operation.

This disclosure is directed to a Schottky Barrier field effect transistor (FET) having a low thermal impedance and to a process of producing it. The thermal impedance of the device is reduced by reducing the thickness of a semiinsulating layer of semiconductor material through which the device is joined to a heat sink. The process for making the device disclosed makes possible the reducing of the layer.

This disclosure is concerned with a thin film, power field effect transistor having a power dissipation capability of 80 watts/cm.2. The transistor has a thin film interdigitated source and drain used in conjunction with a thick film source and drain leads. The thick film source and drain leads essentially eliminates negative feedback resulting from a voltage drop in the source and drain.

摘要:
A field-effect transistor having at least two insulated-gate electrodes comprises an island zone of the same conductivity type as the electrode zones (source and drain zones) situated between two gate electrodes. According to the invention an aperture is provided in said island zone in which aperture a circuit element is provided, particularly a safety diode, which is connected to a gate electrode. In this case a particularly simple and short connection is possible between the circuit element and a gate electrode.
摘要:
Improved semiconductor field-effect transistors have selfregistration and electrical insulation. Conductivity-modified, surface adjacent source and drain regions are formed by diffusing dopants through gate-oxide layer. One embodiment features a conducting gate electrode which is formed from a thin deposited film. In this embodiment a large region of opposite-conductivitytype semiconductor is formed by diffusion through both conducting and oxide films. Complementary ''''N-channel'''' and ''''P-channel'''' devices may be formed on the same substrate by combining two separate embodiments. In such devices the original conductivitytype semiconductor is the base for one FET, while the large conductivity-modified-type region is the base for the other FET. Such modules may be interconnected to form integrated circuits capable of performing a variety of logical functions.
摘要:
A planar phototransistor array having relatively fast response time and being efficiently sensitive to radiation in the near infrared includes a plurality of phototransistors arranged in rows and columns and conductive means which may be selectively coupled by means of an insulated gate enhancement structure to the base regions of each of the transistors. In operation, all transistors are normally biased into a nonconductive condition, but selected ones of the transistors may be biased into photoconduction and provide outputs representative of the light falling thereon.
摘要:
A comb-shaped P-type region is provided on one main face of an N-type substrate to form therebetween a P-N junction terminating at that face. An insulating film is disposed on both the one face of the substrate and the P-region, except for a predetermined portion of the P-region, and a metallic layer is disposed on the film to extend over the P-N junction. A DC voltage across the substrate and P-region is controlled to change the capacitance between the substrate and film of the resulting MIS-type structure.
