Abstract: A dopant is ion-implanted into a second region (52) of a polycrystalline silicon film (50) for a resistive element (5). Nitrogen or the like is ion-implanted into a second region (62) of a polycrystalline silicon film (60) for a resistive element (6). The density of crystal defects in the second regions (52, 62) is higher than that in first regions (51, 61). The density of crystal defects in a polycrystalline silicon film (70) for a resistive element (7) is higher near a silicide film (73). A polycrystalline silicon film (80) for a resistive element (8) is in contact with a substrate (2) with a silicide film in an opening of an isolation insulating film (3). The density of crystal defects in a substrate surface (2S) near the silicide film is higher than that in the vicinity. With such a structure, a current leak in an isolation region can be reduced.

Abstract: Dopant deactivation, particularly at the Si/silicide interface, is avoided by forming deep source/drain implants after forming silicide layers on the substrate and activating the source/drain regions by laser thermal annealing. Embodiments include forming source/drain extensions, forming metal silicide layers on the substrate surface and gate electrode, forming preamorphized regions under the metal silicide layers in the substrate, ion implanting to form deep source/drain implants overlapping the preamorphized regions and extending deeper into the substrate then the preamorphized regions, and laser thermal annealing to activate the deep source/drain regions.

Abstract: A process and structure for mounting a small sample in an opening in a larger substrate by using an intermediate size structure, wherein the small sample is mounted in a small opening in the intermediate size structure which then, in turn, is mounted in an intermediate size opening in the large substrate. As a result, the formation of gaps around the edge of the sample may be voided. The process is carried out by first mounting the test sample in a opening formed with tapered sidewalls through a die with the upper surface of the sample directly abutting the edges of the smallest portion of the tapered opening in the die, The die is then mounted in an opening with tapered sidewalls in a test wafer. The opening in the die is sized to equal, at the smallest end of the tapered sidewalls of the opening, the width and length of the square sample.

Abstract: A field effect transistor (FET) has a channel formed in a pore extending up from a conductive portion of a substrate through a stack of planar layers including a first insulating layer, a gate layer, and a second insulating layer. The pore can be upright or inclined relative to the layers. A nanoparticle used for a mask of a directional etching process ultimately defines the size of the pore and therefore the channel width. The substrate or a doped region of the substrate formed immediately beneath the channel can be a source/drain of the FET with the other drain/source being a doped region adjacent the top of the channel. The gate layer can form the gate or can contact a separate gate inside the pore.

Abstract: The operating temperature range for a vertical PNP transistor can be extended by applying cancellation techniques. The vertical PNP generates a first leakage current from the base-collector region. Another vertical PNP transistor is configured to generate a second leakage current, which is coupled to a current-mirror circuit. The output of the current-mirror circuit is configured to provide a cancellation effect on the first leakage current. The current-mirror circuit and vertical PNP may be configured such that the first leakage current is cancelled in a judicious amount, whereby the effects of leakage current and flare-out in the vertical PNP transistor are minimized or cancelled. The cancellation technique is applicable to temperature sensor circuits, thermal voltage generators, and bandgap circuits.

Moreover, each rib is more conductive than its associated section of shield to provide a less resistive current path than its associated section of shield.

The fluorocarbon gas can be a CFX gas. The at least one plasma source can include a first plasma source that ionizes the fluorocarbon gas by applying RF plasma energy, and a second plasma source that applies a near-zero self-bias to the substrate at an RF frequency during deposition of the passivation layer and a greater bias during deposition of the polymer layer. The passivation layer is deposited prior to the polymer layer to protect the surface of the substrate from damage during the deposition of the polymer layer.

Abstract: An N-type impurity diffusion region is formed in an element forming region surrounded by a field insulating film. In a region between an end portion of the N-type impurity diffusion region and an end portion of the field oxide film, a P-type impurity diffusion region is formed so as to contain an interface level present portion under a bird's beak portion. Thus, a PN junction is formed in a position distant from the interface level present portion. Therefore, even if a voltage is applied to the PN junction, a depletion layer will not reach the interface level present portion. Consequently, a semiconductor device, which suppresses an occurrence of a leakage current along the lower surface of an element isolation insulating film caused by the interface level present portion undesirably included in the depletion layer, as well as a manufacturing method of the same can be obtained.

Trenched field-shaping regions (40) including a resistive path (42) extend through the voltage-sustaining zone (20) to the underlying second region (22), so as to enhance the breakdown voltage of the device. The voltage-sustaining zone (20) and the trenched field-shaping regions (40) are present in both the active device area (A) and in the peripheral area (P) of the device. A further resistive path (53) extends across the first surface (11), outwardly over the peripheral area (P). This further resistive path (53) provides a potential divider that is connected to the respective resistive paths (42) of successive underlying trenched field-shaping regions (40) in the peripheral area (P).
