PURPOSE: A method for forming a CMOS transistor is provided to simplify process and reduce costs by removing an etching process for forming a spacer. CONSTITUTION: The method forms a CMOS transistor to a peripheral area of a semiconductor substrate(100) on which a P-well and a N-well are formed. The first step of the method is to form a gate oxide film(140) on a semiconductor substrate in which each well is formed. The second step is to form gate patterns for a PMOS and a NMOS on the upper of the N- and P-wells respectively. The third step is to form an insulating film for a conformal spacer on each of the gate patterns and the gate oxide film. The fourth step is to form a conductive film for forming a cell pad on the insulating film for the spacer. The fifth step is to remove the conductive film for forming the cell pad using an anisotropic etch and simultaneously leave the conductive film to thickness less than about 200Å by etching a part of the conductive film for the spacer on the gate insulating film(240b). The sixth step is to complete PMOS and NMOS transistors by implanting ions on the insulating film for the spacer remaining on the gate insulating film using the insulating film for the spacer formed on the each gate pattern, side wall thereof and upper thereof as a mask.

A predetermined region of the interlayer dielectric is etched to form an opening exposing a part of the semiconductor substrate on an optimum etching condition that an insulating layer spacer(110) covering a gate region of the access transistor is not damaged. A conductive layer is deposited on the resultant structure having the opening, and patterned to form a landing pad(114) for interconnection.
Abstract:
PURPOSE: A modular multiplying apparatus having an array structure for a high speed encryption is provided to implement a high speed modular multiplication by significantly decreasing a computation amount of an MSB. CONSTITUTION: Two nodes of each row are combined as one node, and regularity is maintained between arrays. An array structure adapted to VLSI is obtained. Nodes X1, X2 and X3 are nodes for obtaining a function. Nodes AA, BB and CC are nodes duplicated by nodes A, B and C by two. The node combination implements a linear structure and an easier hardware of arrays. In the case that the length "n" of a word is even, all nodes except for the control nodes may be combined. Since the array has an odd "n", the original nodes A, B and C exist in the lowest position(namely, most left position). It is possible to obtain an one-dimensional array(for example, bit-serial module multiplier) based on the mapping function. In the array, the most left node of each row generates a control signal. Each control node is formed of four gates(two XOR gates, one AND gate and one NOR gate) or two gates(one XOR gate and one NOR gate). The clock cycle of the array is determined by not the control nodes, but the process nodes.
