Abstract: An electronic circuit device decreases dispersion in the output of the circuit caused by changes in the resistance of the resistors resulting from stress. Resistor positions are selected on the circuit board so that a change in the circuit output caused by a change in resistance of a first resistor group becomes equal to a change caused by a change in resistance caused by a second resistor group, these changes being in opposite directions so as to cancel each other. Alternately, a plurality of resistors are connected to form a composite resistor such that the effect upon resistance of the composite resistor caused by the resistor having decreased resistance is cancelled by the effect upon resistance of the composite resistor caused by a resistor having an increased resistance.

Abstract: A photoresist composition comprising:a resin soluble in an aqueous alkaline solution, having units of an aliphatic cyclic hydrocarbon main frame and units derived from maleic anhydride and/or units derived from a maleimide; anda photosensitive agent in a sufficient amount to promote or hinder the solubility of said resin in an aqueous alkaline solution upon exposure to active radiation so as to create a substantial difference in the solubility as between an exposed portion and a non-exposed portion and to form a positive or negative image by subsequent development with an aqueous alkaline solution.

Abstract: Positive resist patterns prepared by using a derivative of polyacrylic acid esters containing halogen expressed by the following general formula for the resist material; ##STR1## (where A is a structural unit which is derived from monomers having a copolymerable double bond, and X is either a halogen atom or a methyl group. m is a positive integer, n is 0 or a positive integer, n/m is 0 to 2 and m+n are 20 to 20,000. Y.sub.1 to Y.sub.5 are a fluorine or hydrogen atom and at least one of them is a fluorine atom).
