摘要:
A semiconductor device includes a light-receiving element which is connected to a negative power supply and generates conductive carriers by receiving light, an amplifier transistor which is a depletion transistor and amplifies an electrical signal obtained by the conductive carriers, and a transfer gate transistor which is a depletion transistor and is controlled by a negative potential applied to a gate to electrically connect or disconnect the light-receiving element and the amplifier transistor.
摘要:
An electrical fuse (eFuse) has a gate prepared from a conductive or partially conductive material such as polysilicon, a semiconductor substrate having a pipe region in proximity to the gate, and first and second electrode regions adjacent the pipe region. A metal silicide layer is provided on the semiconductor substrate adjacent the pipe region. When a programming voltage is applied, the metal silicide undergoes a thermally induced phase transition in the pipe region. The eFuse has improved reliability and can be programmed with relatively low voltages.

A polishing apparatus includes a polishing jig. The polishing jig includes an elastic balloon member, a fixture, and a fluid supply portion. The fixture airtightly closes the rear opening portion of the balloon member. The fluid supply portion supplies a fluid into a space formed by the fixture and balloon member. The balloon member has a cup shape constructed by a dome portion and a cylinder portion extending backward from the outer periphery of the dome portion. The fixture fixes the opening portion of the cylinder portion of the balloon member.

A programmable element includes a resistive element having a polysilicon film and a metal silicide film or metal film stacked on the polysilicon film. The electric resistance of the resistive element is changed by changing the composition of the metal silicide film or metal film or the chemical bond state using heat, thereby programming on the basis of the change in the electric resistance of the resistor.

摘要:
A semiconductor device with digital and analog circuits has a structure for preventing noise penetration from the digital circuit to the analog circuit. The semiconductor device has a semiconductor substrate, first and second wells independently formed at a surface of the semiconductor substrate, the digital circuit formed at a surface of the first well, and the analog circuit formed at a surface of the second well. The specific resistance of the semiconductor substrate is at least 1000 times as large as the specific resistance of the first well. A conductive guard-ring may be formed in the surface of an area that is between the digital circuit and the second well or between the first well and the second well.
