Patent EP-0387407-A1 (EP)
Inventor: DSCHEN TSING
IPC: H01L21/306
Filed: 1989-11-23
Abstract: A diffraction grating as a high-quality diffraction element in spectrographs or as a cost-effective original for manufacturing embossing dies produced by electroplating is etched into a surface (2) of a wafer (1) which has a characteristic &lang&hkl&rang& direction of an anisotropically acting alkaline etchant. If the diffraction grating has a sharp-edged asymmetrical relief profile (4), ridges (6) with plateau widths (7) of less than 100 nm are required for optical diffraction gratings. Strongly p-doped zones (3) produced by ion implantation and regions outside the grating areas of the surface (2) form an etching mask. The ion implantation is performed using an implantation mask which is produced from a photoresist layer on the wafer (1). The photoresist is firstly exposed in the grating area by means of a stripe pattern with the prescribed grating frequency. The developed photoresist has an undulating profile, and metal is vapour-deposited on it on one side using a prescribed angle of incidence. The photoresist is removed up to the surface (2) by means of reactive ion etching in the zones (3) to be doped and in the regions outside the grating areas. After doping with, e.g., boron ions, the implantation mask is removed and the etching mask, which is particularly resistant to undercutting, remains in the surface (2). <IMAGE>

Abstract: A pressure sensor (10) having over-protection for use in environments which subject the sensor to large pressure overloads, such as may occur when such sensor is exposed to jet and automobile engine backfires, explosive gas furnace ignitions and similar high pressure events. Essentially two capacitive sensors are bonded together, diaphragm-to-­diaphragm, with the diaphragms (111A/111B) spaced but juxtaposed and forming a closed, reference cavity chamber (114) between them, along with a central, side, wall spacer (116C). The capacitance variation with differential pressure is measured between, the two diaphragms and with reference to their respective bases (112A/112B). Each of the diaphragms preferably is provided with a center bearing or stops (115A/115B) for accepting the load when over-pres­sured. When in contact at the center, the stiffness of the combined pair of diaphragms is increased several fold over that of a single diaphragm. Furthermore, providing for bottoming stops for the combination on either side of the sensor prevents deflection to the breaking point, because the presence of the opposed bottoming stops stiffens its respective diaphragm.

Abstract: Reinforcing fibers having a diameter of 0.1-10 µm and a length of 5-200 µm are pelletized and granulated into agglomerates which have a size of 0.1-10 mm and a bulk density of 0.2-1.0 kg/liter. 
     To pelletize, powders of reinforcing fibers are moistened with water while mixing to form primary aggregates. Then, the powders and the primary aggregates are subjected to a rolling movement to cause the primary aggregates to grow into secondary aggregates having desired size distribution. Finally, the secondary aggregates are dried to obtain pelletized or granulated agglomerates of reinforcing fibers. 
     Handling of reinforcing fibers is facilitated because the agglomerates are less bulky and less likely to fly up in the air. When blended into molding materials for fiber reinforcement, however, the agglomerates are readily disintegrated back into segregated individual fibers to provide homogeneous dispersion.
