Patent EP-0071204-A2 (EP)
Inventor: PLISKIN WILLIAM AARON
IPC: H01L21/70
Filed: 1982-07-23
Abstract: A method is described for forming the recessed dielectric isolation in a silicon substrate. This method involves first forming trenches (16) which are less than 1 micron in depth in areas of one principal surface of the silicon substrate where isolation is desired. Where, for example, an NPN bipolar transistor structure is planned to be formed it is usually necessary to have a P+ region (6) underneath the recessed dielectric isolation to allow full isolation between the various bipolar transistor devices. A PNP transistor uses an N+ region underneath the isolation. Where a field effect transistor is planned a channel stop (30) can be substituted for the P+ region. Under the circumstance of bipolar devices, the P+ region (6) is formed in the substrate (2) prior to the deposition of an epitaxial layer (8) thereover. The trench formation is caused to be formed through the epitaxial layer and into the P+ regions therein. The surface of the trenches (16) are then oxidized in an oxidizing ambient to form a silicon dioxide layer (18) thereon. A glass (20) is deposited over this principal surface. The glass used has a thermal coefficient of expansion that approximates that of silicon and has a softening temperature of less than 1200°C. The structure is then heated to a temperature that allows the flow of the deposited glass on the surface so as to fill the trenches. The glass on the principal surface above the trench can be removed by a reactive ion etching method. Alternatively and preferably, the glass is removed from areas other than the immediate area of the trench by lithography and etching techniques followed by a second heating of the structure to cause the glass flow to result in surface planarization.

Abstract: A process for making washing powder having a high content of sodium soap in which the tendency to form clots and gels is reduced. The reduction is effected by impregnating spray-dried or spray-cooled powder with a specified amount of a water-soluble sodium salt. The amount specified is sufficient to produce a solution of sodium ions having 0.5 to 4 molar initial concentration in the immediate locality of the individual spray-dried particles.

Abstract: In order to manufacture a building material or building additive from in particular waste material from hard coal mining, a method is used in which the waste material is initially homogenised, then formed into a stack in a previously determined exactly defined amount, provided with a cover and then burnt at preferably 950 DEG C. In the stack, channels or a complete support frame of channels is provided. Via these channels the stack is supplied with the necessary fuel, principally however with air. Later, the stack can also be extinguished by introducing water through these channels. The cover consists of a mixture of ground-damp fine grade or very fine grade mining waste with limestone dust or other materials which prevent the escape of sulphur-containing gases, or of a sheet metal construction which partially or completely covers the stack and can be cooled. <IMAGE>

Abstract: An ISL structure is produced by a four step diffusion process. A first diffusion produces the main collector tub (18). A second diffusion produces a thin extension (18a) of the collector tub which is more lightly doped than the collector tub. A third diffusion produces the base region (24) and circumscribing channel stop regions (26). The base region lies partly over the main collector tub and partly over the thin extension of the collector. The fourth diffusion produces the emitter (30) which lies over the main collector tub. The four step diffusion process provides better control over the base thickness so that a smaller thickness than that obtainable with an epitaxial structure is possible. With a smaller base thickness, a higher current gain for the PNP clamping transistor is achieved.

Abstract: The reflectance of a mirror (1) is variable to provide a dipping car mirror. The mirror (1) comprises a liquid crystal cell formed by two transparent slides (6, 7) coated on their inner surfaces with electrodes (9, 10). The front electrode (9) is transparent whilst the rear one is a reflector (10) or a separate reflecting surface is provided. Between the slides (6, 7) is a layer 8 to 12 µm thick of a cholesteric liquid crystal material (11). The slides (6, 7) are surface treated to give a high tilt homogeneous boundary condition, i.e. the liquid crystal molecules at the slide wall incline at a high (20-75°) tilt to the surface. A control unit (12) applies either a high voltage (10 volts at 1kHz) or a low voltage (1 to 2 volts at lkHz). The high voltage results in the liquid crystal (11) adopting a light transmissive state. In this state light reflects off the rear (10) of the cell. The low voltage state is a scattering state for the liquid crystal material. In the scattering state light reflects off the front slide (6) and is about 1/10 that reflected off the rear electrode (10). A photocell (4) controls the switching of the cell. With zero voltage across the cell the liquid crystal material adopts a light transmitter state.

Abstract: For preparing polyoxyalkylenediol-a, ω- bisallyl policar- bonates, diallyl carbonate is reacted in a first reaction stage with a polyoxyalkylenediol having a mol wt between 400 and 4500 in the presence of a transesterification catalyst at a temperature in the neighbourhood of 100°C and under reduced pressures, whereafter, in a second reaction stage, the product as obtained from the first stage is treated at a temperature between 70°C and 150°C under reduced pressures, still in the presence of a transesterification catalyst. By so doing, the chain extension of the bisallyl carbonate of the polyoxyalkylenediol is achieved, whereas the unreacted diallyl carbonate coming from the first stage, and that produced in the second stage, are eliminated, and the final reaction product can thus be collected.
