IPC: H01L21/8238
Filed: 1990-05-01
Abstract: An integrated circuit is disclosed which includes at least one NMOS transistor having a P-well formed in an N-type epitaxial layer, the P-well being formed of a first, relatively high diffusivity P-type dopant and a second, relatively lower diffusivity P-type dopant, the dopants being diffused into the N-type epitaxial layer to form an effective P-well junction with the N-type epitaxial layer at a predetermined depth. A lower region of the P-well preferably contains a relatively higher concentration of electrically-active ions of the first P-type dopant and an upper region of the P-well contains a relatively higher concentration of electrically-active ions of the second P-type dopant, the effective P-well junction depth being determined by the first P-type dopant. A P-type layer may be situated below the N-type epitaxial layer, with the effective upper boundary of an N+ buried layer located at a predetermined distance below the P-well junction depth, whereby a region of the N-type epitaxial layer situated between the effective P-well junction and the N+ buried layer defines a depletion region of sufficient depth to support a predetermined reverse-bias voltage. The first P-­type dopant is preferably Aluminum and the second P-type dopant is preferably Boron. 
     The P-well preferably comprises an N-type region of implanted at an energy of about 180 KeV with Aluminum ions at a concentration of 4×10¹³ - 7×10¹³ cm⁻³, implanted at an energy of 50-100 Kev with Boron ions at a concentration of 4×10¹¹ - 1×10¹³ cm⁻³, and diffused for about 170 minutes at a temperature of about 1150 °C. The P-well formed in accordance with the invention may be advantageously used in monolithic circuits having DMOS and CMOS circuit elements for control and switching of relatively high voltages, such as 80 volts.

Abstract: A method and apparatus are disclosed for the construction of complex data structures for use in efficient communications between a server (19, 20) and a requester (12, 30) in a database management system. The complex data structures may typically include fixed length static components, fixed length dynamic components and variable length dynamic components. Multiple fixed length data templates (36) are created, each of which preferably includes at least one fixed length static component mapped therein. Selected data templates may also include at least one empty field or "hole" into which a fixed length dynamic component may be mapped. Associated with each such selected data template is a replacement table (42) which contains an entry for each empty field within the data template and the characteristics of the fixed length dynamic component which is to be mapped into that empty field. A second table (48) is provided for each fixed length dynamic component which specifies the source of that dynamic component. In a preferred embodiment of the present invention the source thus specified may be a direct reference to an address location or an indirect reference, such as a reference to a function which may be utilized to calculate the dynamic component. Thus, by selecting an appropiate data template which includes at least one static component mapped therein and subsequently utilizing its associated tables to determine the dynamic components which will be mapped into the template it is possible to efficiently create a complex data structure. Such complex data structures may be then be linked to individual variable length dynamic components to create a complex data structure having any desired combination of data components.

Abstract: A data transmission method is provided which transfers data to an adapter (30) from a processor module (200) and transfers the data to an input/output device (1) from the adapter. The method includes the following steps. The first step is to transfer data from the processor module to a data buffer (30a) provided in the adapter. The data buffer has a storage capacity equal to or greater than a predetermined storage capacity. The second step is to determine whether or not an error occurs in the processor module during the first step. The third step is to determine whether or not the data has been completely transferred to the data buffer provided in the adapter without having any error. The fourth step is to transfer the data in the data buffer provided in the adapter to the input/output device when the third 1step determines that the data has been completely transferred to the data buffer provided in the adapter irrespective of whether the second step determines that the error occurs during the first step. The data in the data buffer provided in the adapter is not transferred to the input/output device when the second step determines that the error occurs in the processor module during the first step before the data has been completely transferred to the input/output device.

Abstract: The architecture of the signal processor operates the ALU (10) and MACU (11) through a register file (9) that serves as a general buffer pool for operands. All operand trans­fers take place between data memory through this register file (9) and ALU (10) and MACU (11) have equal access to all data in the file (9). Further the file (9) is the buffer for previous ALU results. In this manner, the bandwidths of all the individual units, data buses (19, 20), ALU (10) and MACU (11) can be fully utilized without conflicts. In general, the proposed configuration relies on the redundance or latency in many signal processing computations where data and results are used and reused in the overall computation and must remain in holding regis­ters. The register file gives this capability providing these operands for use independently by both the ALU (10) and MACU (11). Without a common register file, operands would have to be reloaded as the computation continues. These redundant loads reduce the throughput for the compu­tation.
