Abstract: A surgical patient support includes a foundation frame, a support top, and a brake system. The foundation frame includes a first column and a second column. The support top is coupled to the first column and the second column for rotation about a top axis extending along the length of the support top. A single-handle unlock for the support top is also provided.

Abstract: A method for making a transistor is provided which comprises (a) providing a semiconductor structure having a gate (211) overlying a semiconductor layer (203), and having at least one spacer structure (213) disposed adjacent to said gate; (b) removing a portion of the semiconductor structure adjacent to the spacer structure, thereby exposing a portion (215) of the semiconductor structure which underlies the spacer structure; and (c) subjecting the exposed portion of the semiconductor structure to an angled implant (253, 254).

Abstract: A resistive device (44) and a transistor (42) are formed. Each uses a portion of a metal layer (18) that is formed at the same time and thus additional process steps are avoided to remove the metal from the resistive device. The metal used in the resistive device is selectively treated to increase the resistance in the resistive device. A polycrystalline semiconductor material layer (34) overlies the metal layer in the resistive device. The combination of these layers provides the resistive device. In one form the metal is treated after formation of the polycrystalline semiconductor material layer. In one form the metal treatment involves an implant of a species, such as oxygen, to increase the resistivity of the metal. Various transistor structures are formed using the untreated portion of the metal layer as a control electrode.

Abstract: A method for forming a semiconductor device including forming a semiconductor substrate; forming a gate electrode over the semiconductor substrate having a first side and a second side, and forming a gate dielectric under the gate electrode. The gate dielectric has a first area under the gate electrode and adjacent the first side of the gate electrode, a second area under the gate electrode and adjacent the second side of the gate electrode, and a third area under the gate electrode that is between the first area and the second area, wherein the first area is thinner than the second area, and the third area is thinner than the first area and is thinner than the second area.

Abstract: A semiconductor device is formed by patterning a semiconductor layer to create a vertical active region and a horizontal active region, wherein the horizontal active region is adjacent the vertical active region. The semiconductor layer overlies an insulating layer. A spacer is formed adjacent the vertical active region and over a portion of the horizontal active region. At least a portion of the horizontal active region is oxidized to form an isolation region. The spacer is removed. A gate dielectric is formed over the vertical active region after removing the spacer. A gate electrode is formed over the gate dielectric. However, forming the spacer is optional.

Abstract: Predetermined regions of a transistor are activated using a buried energy absorbing layer. The buried energy absorbing layer is under a semiconductor layer, in which a transistor is being formed. Amorphous regions are formed within the semiconductor layer on either side of a control electrode and a gate dielectric. An energy source with a wavelength that is not absorbed by the amorphous regions or the control electrode is applied to the transistor and absorbed by the energy absorbing layer. The energy absorbing layer transfers the energy into heat, which is at a temperature greater than or equal to the melting temperature of the amorphous regions and less than the melting temperature of the semiconductor layer. Due to the heat, the amorphous regions melt and recrystallize, thereby becoming electrically active. However, the control electrode does not melt.
