Inventor: COOK ROBERT KIMBAL
IPC: H01L21/205

Abstract: A method of controlling the interfacial oxygen concentration of a monocrystalline/polycrystalline emitter includes the steps of: passivating the monocrystalline silicon surface by immersing the wafer in a diluted HF acid solution; transferring the wafer into a high vacuum environment; heating the wafer to between 400 and 700 _C; exposing the monocrystalline silicon surface to a gas having a partial pressure of oxygen of between 10⁻⁵ to 1 Torr for between 1 and 100 minutes; and, depositing polysilicon onto the monocrystalline silicon surface. 
     In a typical exemple of manufacturing a NPN bipolar transistor (70) comprises a P- doped substrate (80); a N+ doped monocrystalline subcollector (90); a N doped monocrystalline silicon collector (100); a P doped base (102); a P+ doped polysilicon contact layer (106); and, insulating layers (108, 110). A hole (114) is then etched through the insulating layers (108, 110) and the contact layer (106). A partial reoxidation of contact layer (106) is then done to form an insulation layer (109) between the P+ polysilicon of contact layer (106) and hole (114). The surface of P doped base (102) which is exposed at the bottom of the hole (114) is then oxidized according to the methods of the present invention to thereby form an interface layer (116) of silicon having a specific concentration of oxygen. A layer of polycrystalline silicon (112) is then deposited in the hole (114), implanted with N dopant (e.g. Arsenic) and annealed to thereby form the emitter, which is comprised of n+ area (104), SiO x  interface (116) and polysilicon (112).

Abstract: The invention relates to a method of improving the sensitivity and speech immunity of a receiver in conjunction with DTMF-reception. 
     According to a first aspect of the invention, the number of zero-crossings of the input signal are counted during one of a number of measuring intervals in real time at frequencies which occur in the low frequency group and the high frequency group of a DTMF-signal. At the end of each of the measuring intervals, the number of zero-crossings in a current measuring interval is compared for each frequency group, with a corresponding number of zero crossings in a number of nearest preceding measuring intervals, and the magnitude of any difference is established. The input signal is treated as a DTMF-signal when the difference is at most equal to a permitted limit value. 
     According to a second aspect, an energy parameter representative of the tone energy of an input signal is measured in real time in each of the DTMF-frequency group bands during each of a number of measuring intervals. During the end of each measuring interval, there is determined the average value of the total measured parameters over the measuring intervals from the beginning of a current signal. The difference between each of the current energy parameters in the two bands and the average value determined parameter is determined, and at least three threshold values for this difference are determined, namely a normal value beneath which a DTMF-signal is considered to exist, at least one greater-than-normal value, and at least one smaller-than-normal value. A check is made to see whether the difference in any of the bands lies above the normal value, and if such is the case, it is ascertained whether or not the difference concerned also lies above the greater-than-normal value. The difference in the other band is compared with the smaller-than-normal value in order to establish whether or not the difference lies beneath this value, in which case a DTMF-signal is considered to exist. 
     According to a third aspect, when an interference frequency is encountered for the first time during one of a number of measuring intervals when decoding a DTMF-signal, this fact is noted and if the same interference tone is encountered in a following measuring interval, the interference tone is tolerated.

Abstract: A distance measuring arrangement includes means for modulating a transmitted microwave signal with a first pseudo-random noise code at 15 and an IF signal at 13. The returns are modulated with a second pseudo-random noise code at 18 which is identical in pattern to the first code but having a different frequency. When the two codes come into alignment, a detection peak is generated which is compared by processor 25 with a reference peak signal to give a time offset representative of the distance travelled by the transmitted signal. The arrangement is particularly useful for monitoring the levels of liquids in a tank

Abstract: Font-independent spotting of user-defined keywords in a scanned image. Word identification is based on features of the entire word without the need for segmentation or OCR, and without the need to recognize non-keywords. Font-independent character models are created using hidden Markov models (HMMs) and arbitrary keyword models are built from the character HMM components. Word or text line bounding boxes are extracted from the image, a set of features based on the word shape, (and preferably also the word internal structure) within each bounding box is extracted, this set of features is applied to a network that includes one or more keyword HMMs, and a determination is made. The identification of word bounding boxes for potential keywords includes the steps of reducing the image (say by 2x) and subjecting the reduced image to vertical and horizontal morphological closing operations. The bounding boxes of connected components in the resulting image are then used to hypothesize word or text line bounding boxes, and the original bitmaps within the boxes are used to hypothesize words. In a particular embodiment, a range of structuring elements is used for the closing operations to accommodate the variation of inter- and intra-character spacing with font and font size.

Abstract: A vehicle braking force controller for controlling braking force of a vehicle by changing brake fluid pressure effected by a fluid pressure controller (50) has a deceleration detector (1) and a computer (4). The computer (4) calculates a vehicle deceleration (Aw), a target deceleration (Tg) of the vehicle, and a pressure adjustment speed (VP) at which the brake fluid pressure increases or decreases using the target deceleration (Tg) and the vehicle deceleration (Aw). The pressure adjustment speed calculator (45) calculates the brake fluid pressure adjustment speed (VP) using a brake fluid pressure adjustment volume (DP) which is proportional to a difference between the detected vehicle deceleration (Aw) and the calculated target deceleration (Tg), and a target tracking time (TC) representing a time required to adjust the brake fluid pressure with the pressure adjustment volume (DP). The computer controls the brake fluid pressure according to the pressure adjustment speed (VP). Thus, the vehicle braking force controller quickly starts the deceleration so that the actual vehicle deceleration does not overshoot the target deceleration.

Abstract: A semiconductor device and process for making the same are disclosed which incorporate a relatively large percentage of holmium dopant (0.3% to 3%) into a BST dielectric film 24 with small grain size (e.g. 10 nm to 50 nm). Dielectric film 24 is preferably disposed between electrodes 18 and 26 (which preferably have a Pt layer contacting the BST) to form a capacitive structure with a relatively high dielectric constant and relatively low leakage current. Apparently, properties of the thin film deposition and small grain size, including temperatures well below bulk BST sintering temperatures, allow the film to support markedly higher defect concentrations without holmium precipitation than are observed for bulk BST. For holmium doping levels generally between 0.3% and 3% (compensated with titanium and/or manganese), better than 50% improvement in dielectric constant and two to six orders of magnitude reduction in leakage current (compared to undoped BST) have been observed for such films.
