摘要:
An array of radiation sensing devices, each including a pair of conductor-insulator-semiconductor capacitors, arranged in rows and columns in which the row stripes or lines form row connected capacitors in relation to selected surface regions of a semiconductor substrate and in which the column stripes or lines form column connected capacitors in relation to the selected surface regions. Each of the row stripes overlies first portions of the selected surface regions of a respective row. Each of the column stripes overlies entirely the selected surface regions of a respective column.

A magnetic circulator is incorporated into a multi-chip module using a microwave high density interconnect (HDI) structure. A prepackaged circulator can be inserted into a ready-made high density interconnected multi-chip module; this prepackaged circulator may use a stripline design having a signal line with two ground planes above and below the signal line, or a microstrip transmission line design having one signal line and one ground plane below the signal line. Alternatively a circulator can be manufactured directly in a high density interconnected multi-chip module, with a stripline, or a microstrip transmission line design.
摘要:
A method of forming in a silicon substrate an active region bounded by a field of silicon dioxide is described. On top of a mesa formed in the silicon substrate is provided a three layered structure including a first thin layer of silicon dioxide in contact with the top of the mesa, a second thicker layer of silicon nitride overlying the thin layer of silicon dioxide and a third layer of silicon dioxide overlying the layer of silicon nitride. A further layer of silicon nitride is formed over the three layered structure and the exposed surfaces of the silicon substrate. Spacer portions of silicon nitride are formed on the sides of the mesa and the three layered structure by anisotropically etching the fourth layer of silicon nitride. By controlling the thicknesses of the first, second and third layers, the width of the spacer portions is optimized to prevent lateral oxidation of the active region. By optimizing the thicknesses of the first and second layers of the three layered structure, lattice stresses in the active region resulting from thermal cycling of the device having layers with different thermal coefficients of expansion are reduced during field oxidation.

An integrated circuit structure for reducing propagation delay is described. Integrated circuits include at least a pair of regions in each of which are located a respective plurality of functional cells and which are spaced apart by an interconnection region in which interconnection lines are provided connecting elements of the functional cells of one functional cell region with elements of the functional cells of the other functional cell region. Field oxide is provided in the interconnection region substantially greater in thickness than the field oxide in the regions of the functional cells thereby substantially reducing the capacitance and hence propagation delay of the interconnection lines. Formation of the field oxide of the interconnection region independent of the formation of the field oxide in the functional cell regions enables optimization of the field oxide in the interconnection region for minimum propagation delay without compromising functional cell formation in the functional cell regions.

A method of reducing lateral field oxidation in the vicinity of the active regions of integrated circuits is described. The method utilizes a three layered masking structure for masking the active regions during field oxidation including a first very thin layer of silicon nitride in contact with the active region of the substrate, a second thin layer of silicon dioxide overlying the very thin layer of silicon nitride, and a third thick layer of silicon nitride overlying the second layer of silicon dioxide.

A method of etching a layer of material on the surface of a substrate of silicon dioxide utilizes an etch mask constituted of a binary silicate glass. The binary silicate glass is removed subsequent to the etching of the layer without affecting the substrate of silicon dioxide.

A method of etching a desired pattern in a layer of indium tin oxide formed on a substrate of a semiconductor or an insulating material in which the desired pattern is formed of a hardened photoresist on the layer of indium tin oxide and thereafter the substrate and the indium tin oxide layer with the hardened resist thereon is immersed in a solution of concentrated hydrobromic acid for a time sufficient to etch away the indium tin oxide unmasked by the hardened photoresist.

A thermal processor for at least one semiconductor wafer includes a reactor chamber having a material substantially transparent to light including a wavelength within the range of about 200 nanometers to about 800 nanometers for holding the at least one semiconductor wafer. A coating including a material substantially reflective of infrared radiation can be present on at least a portion of the reactor chamber. A light source provides radiant energy to the at least one semiconductor wafer through the coating and the reactor chamber. The light source can include an ultraviolet discharge lamp, a halogen infrared incandescent lamp, or a metal halide visible discharge lamp. The coating can be situated on an inner or outer surface of the reactor chamber. If the reactor chamber has inner and outer walls, the coating can be situated on either the inner wall or the outer wall.

摘要:
A method of fabricating a semiconductor device having a symmetric and complementary P-well and N-well. The novel method involves the introduction of a first dopant type into a semiconductor substrate directly through those regions of an oxide layer and a nitride layer which do not underlie a first mask layer. The first mask layer is removed and a second mask layer is formed. A complementary dopant type is then introduced into the semiconductor substrate directly through those regions of the oxide layer and nitride layer which do not underlie the second mask layer. The second mask layer is removed and the dopant ions are simultaneously subjected to thermal drive in to thereby form adjacent wells of opposite dopant type in the semiconductor substrate.
