Title: Integrated circuit chip and processing method for unused pad
Inventor: SHIODA KYOICHI
IPC: H01L27/04
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To eliminate the need of each setting through the use of the user program of the input/output control circuit of an unused input/output pad by installing a switching element which on/off-operates in accordance with a control signal on an operation power supply route to a Schmitt circuit. SOLUTION: A P channel transistor for power supply control and an N channel transistor for power supply control, which are turned on/off in accordance with a control signal are installed on an operation power supply route to a Schmitt circuit outputting an input signal to an inner circuit. When an unused input/output pad which is not connected to an input/output lead 36 is generated, a second control pad 35 is connected to a high voltage side power lead 38. Thus, the P channel transistor and the N channel transistor for power supply control can be set to an off operation at the time of packaging. Thus, the unused input/output pad which is not connected to the lead can efficiently be processed when it is used in a package with the small number of pins.

Abstract: PURPOSE: To increase integration degree by a method wherein a poly-Si layer uniformly formed is selectively etched to form a thin layer portion and a highly resistance element in that portion.  
     CONSTITUTION: An element isolating region 23 is made by selectively oxidizing a Si substrate 21, and a poly-Si layer 24 is accumulated on the substrate after the formation of an oxide gate film. Next by providing a resist mask 25, ion injection is added to the surface layer while selecting the quantity of addition and energy.
