摘要:
Each of a pair of like-polarity IGFETs (40 or 42 and 240 or 242) has a channel zone (64 or 84) situated in body material (50). Short-channel effects are alleviated by arranging for the net dopant concentration in the channel zone to longitudinally reach a local surface minimum at a location between the IGFET's source/drain zones (60 and 62 or 80 and 82) and by arranging for the net dopant concentration in the body material to reach a local subsurface maximum more than 0.1 μm deep into the body material but not more than 0.4 μm deep into the body material. A pocket portion (100/102 or 104) extends along both source drain zones of one of the IGFETs. A pocket portion (244 or 246) extends largely along only one of the source/drain zones of the other IGFET so that it is an asymmetrical device.
摘要:
A trenched-isolated semiconductor structure is created by a process that entails forming a patterned trench (54) along an upper surface of a semiconductor body (40). A dielectric layer (56) is provided over the upper semiconductor surface. The dielectric layer is covered with a smoothening layer (60) whose upper surface is smoother than the upper surface of the dielectric layer. The smoothening layer is removed starting from its upper surface. During the removal of the smoothening layer, upward-protruding material of the dielectric layer progressively becomes exposed and is also removed. As a result, the remainder of dielectric layer has a smoother upper surface than the initial upper surface of the dielectric layer.

An IGFET (40 or 42) has a channel zone (64 or 84) situated in body material (50). Short-channel threshold voltage roll-off and punchthrough are alleviated by arranging for the net dopant concentration in the channel zone to longitudinally reach a local surface minimum at a location between the IGFET's source/drain zones (60 and 62 or 80 and 82) and by arranging for the net dopant concentration in the body material to reach a local subsurface maximum more than 0.1 μm deep into the body material but not more than 0.1 μm deep into the body material. The source/drain zones (140 and 142 or 160 and 162) of a p-channel IGFET (120 or 122) are provided with graded-junction characteristics to reduce junction capacitance, thereby increasing switching speed.
摘要:
At least one source/drain zone (140, 142, 160, or 162) of an enhancement-mode insulated-gate field-effect transistor (120 or 122) is provided with graded junction characteristics to reduce junction capacitance, thereby increasing switching speed. Each graded junction source/drain zone contains a main portion (140M, 142M, 160M, or 162M) and a more lightly doped lower portion (140L, 142L, 160L, or 162L) underlying, and vertically continuous with, the main portion. The magnitudes of the threshold voltages of a group of such transistors fabricated under the same post-layout fabrication process conditions so as to be of different channel lengths reach a maximum absolute value VTAM when the channel length is at a value LC, are at least 0.03 volt less than VTAM when the channel length is approximately 0.3 μm greater than LC, and materially decrease with increasing channel length when the channel length is approximately 1.0 μm greater than LC.
摘要:
A signal processing apparatus for a multi-mode satellite positioning system includes a band-pass filter, a local oscillator circuit, a first mixing circuit, a second mixing circuit, an analog-to-digital converter and a baseband circuit. By properly allocating a local frequency, radio frequency (RF) signals of a Global Positioning System (GPS), a Galileo positioning system and a Global Navigation System (GLONASS) are processed via a single signal path to save hardware cost.
摘要:
Each of a pair of differently configured like-polarity insulated-gate field-effect transistors (40 or 42 and 240 or 242) in a semiconductor structure has a channel zone of semiconductor body material, a gate dielectric layer overlying the channel zone, and a gate electrode overlying the gate dielectric layer. For each transistor, the net dopant concentration of the body material reaches multiple local subsurface maxima below a channel surface depletion region and below largely all gate-electrode material overlying the channel zone. The transistors have source/drain zones (60 or 80) of opposite conductivity type to, and halo pocket portions of the same conductivity type as, the body material. One pocket portion (100/102 or 104) extends along both source/drain zones of one of the transistors. Another pocket portion (244 or 246) extends largely along only one of the source/drain zones of the other transistor so that it is asymmetrical.
