  • Methods of marking and electrically identifying an article
    Patent number: 4437229
    Abstract: A hybrid integrated circuit package (11) typically includes a circuit substrate or article (12) on which are formed thin film components (17, 18, 19) of a circuit (22) and to which is bonded at least one semiconductor chip (21). Prior to bonding the chip (21) to the article (12) the circuit (22) undergoes various tests and adjustment operations. An electric element, preferably a resistance element (36), is formed on the article (12). The element (36) is functionally independent of the circuit (22) on the article (12). A first, initial value of the element (36) marks the article (12) as belonging to a first group of articles having first circuit characteristics. The initial value of the element (36) is selectively altered to a second value upon a determination that the article (12) has circuit characteristics other than those of the first group. In the described preferred embodiment the first group is a group of electrically acceptable articles (12), while other characteristics are those of defective articles.
