Patent number: 5790385Abstract: Disclosed are a structure and a method of manufacture of a one-chip electronic composite component which is reduced of size while providing a resistance value properly adjusted. A resistor is formed on an insulator substrate. The resistor has a trimming groove by which a resistance value thereof is adjusted. An electronic element is in electrical connection with the resistor on the substrate. A protection layer covers at least the trimming groove. The resistor is disposed close to one side edge of the substrate with respect to a centerline extending lengthwise of the substrate. The trimming groove extends toward the one side edge of the substrate from a side defining the resistor remote from the one side edge of the substrate.Type: GrantFiled: September 24, 1996Date of Patent: August 4, 1998Assignee: Rohm Co., Ltd.Inventor: Masanori Tanimura
