Abstract
A semiconductor device with a load resistor is manufactured such that a contact is formed at both ends of the load resistor, and at least one contact is formed between the contacts, in order to prevent impurities from being generated within each contact while the contacts are being generated by etching an insulation layer phenomena of electric charge build up from occurring when an etching process fabricates an insulation layer to generate the contact in a long load resistor located under the insulation layer and insulated electrically and physically.
