Patent number: 8318032Abstract: A method for delineating a metallization pattern in a layer of sputtered aluminum or sputtered copper using a broad spectrum high intensity light source. The metal is deposited on a polymeric substrate by sputtering, so that it has a porous nanostructure. An opaque mask that is a positive representation of the desired metallization pattern is then situated over the metallization layer, exposing those portions of the metallization layer intended to be removed. The masked metallization layer is then exposed to a rapid burst of high intensity visible light from an arc source sufficient to cause complete removal of the exposed portions of the metallization layer, exposing the underlying substrate and creating the delineated pattern.Type: GrantFiled: December 21, 2007Date of Patent: November 27, 2012Assignee: Motorola Solutions, Inc.Inventors: John B. Szczech, Daniel R. Gamota, Tomasz L. Klosowiak, Jerzy Wielgus

Patent number: 8134233Abstract: A method and apparatus for forming controlled stress fractures in metal produces electrically isolated, closely spaced circuit sub-entities for use on a metallized printed wiring board. A polymeric substrate has a layer of metal adhered to the surface, and the metal layer is formed into entities. Each entity has a fracture initiating feature formed into it, which serves to initiate and/or direct a stress crack that is induced in the metal. The entities are fractured in a controlled manner by subjecting the substrate and the entities to mechanical stress by a rapid thermal excursion, creating a stress fracture in the entity extending from the fracture initiating feature. The stress fracture divides each entity into two or more sub-entities that are electrically isolated from each other by the stress fracture. The resulting structure can be used to form circuitry requiring very fine spaces for high density printed circuit boards.Type: GrantFiled: July 30, 2007Date of Patent: March 13, 2012Assignee: Motorola Solutions, Inc.Inventors: Jerzy Wielgus, Daniel R.

Patent number: 7780345Abstract: A method and apparatus for an irreversible temperature sensor for measuring a peak exposure temperature. The apparatus is fabricated by printing an admixture of conductive nanoparticles on a dielectric substrate to form a film. The film has an electrical resistance that is inversely proportional to the exposure temperature. The electrical resistance also irreversibly decreases as the exposure temperature of the film increases. A portion of the film is exposed to a pulse of electromagnetic energy sufficient to render it substantially more electrically conductive than the portion that was not exposed. In use, the peak exposure temperature is determined by measuring the electrical resistance of the non-altered portion of the film and the electrical resistance of the portion that was exposed to the pulse of electromagnetic energy, and subtracting the electrical resistance of the altered portion from the electrical resistance of the portion that was not altered, to provide a difference value.Type: GrantFiled: December 19, 2007Date of Patent: August 24, 2010Assignee: Motorola, Inc.Inventors: Jerzy Wielgus, Daniel R. Gamota, John B. Szczech, Kin P. Tsui, Jie Zhang

Patent number: 7667285Abstract: A protective photochromic barrier film for a light-sensitive printed electronic substrate. Light-sensitive semiconductor devices on a dielectric substrate are electrically connected by conductors. A barrier layer containing photochromic dyes covers some or all of the light-sensitive semiconductor devices. Upon exposure to visible, infrared, or ultraviolet light, the photochromic dyes change chemical structure and decrease the amount of visible or non-visible light that can impinge upon the light-sensitive electronic devices. Upon removal of the visible or non-visible light, the photochromic dyes either revert to their original structure or maintain their altered state.Type: GrantFiled: December 14, 2006Date of Patent: February 23, 2010Assignee: Motorola, Inc.Inventors: Jerzy Wielgus, Daniel R.

Publication number: 20090080233Abstract: A printed read only memory (ROM) device that consists of an array of memory resistors, a reference resistor, and analog-to-digital circuit is disclosed. Resistance values are dependent on the data to be stored in the read only memory. During read operation, a resistor in the array is powered, activating a voltage divider between the powered resistor and the reference resistor. The analog-to-digital circuit will read the divided voltage level between the two resistors, compare the voltage supply level and interpret it into bits of memory data. During the manufacturing of the ROM circuit, an array of memory resistors is printed as the means for storage of the data. Resistive inks of specific resistance values are selected and printed in a preferred layout that includes a reference resistor coupled to the determined array of memory resistors and an analog to digital converter so as to form a read only memory with the received data.Type: ApplicationFiled: September 21, 2007Publication date: March 26, 2009Applicant: Motorola, Inc.Inventors: Kin P.

Publication number: 20080124528Abstract: A printed electronic device and methods for determining the electrical value of the device. A dielectric material is contact printed on a substrate using a preset force. The substrate has a pressure sensitive material that is optically responsive in direct proportion to the amount of force imparted by the contact printing. The force of the contact printing causes the pressure sensitive material to form a pattern that is quantifiable to the amount of force. The pattern is then optically inspected and compared to sets of standards in order to quantify the amount of force that was used in printing. The thickness of the printed dielectric material is then calculated based on the quantified force by comparing to another set of standards. The electrical value of the printed material is calculated based on the calculated thickness of the printed dielectric material, the surface area of the printed dielectric material, and the dielectric constant of the dielectric material.Type: ApplicationFiled: November 29, 2006Publication date: May 29, 2008Applicant: MOTOROLA, INC.Inventors: Jerzy Wielgus, Daniel R.
