Title: Heat transferable laminate
Inventor: PARKER TIM
IPC: B44C1/17
Filed: 1989-01-23
Granted: 1991-11-21
Abstract: An improved release system for heat transferable laminates wherein a transferable substrate which contains a design layer is transferred from a carrier web onto an article such as a plastic bottle or container upon application of heat and pressure. The carrier web includes a nonwax polyethylene layer. The improved release system includes a polyethylene layer portion of the carrier web in contact with and adhered to a nonwax transfer layer portion of the transferable substrate. The transferable substrate including the ink design layer transfers to the article upon application of heat to the carrier while the article contacts the laminate. The transferred substrate on the article is clear and exhibits improved scuff and abrasion resistance. The nonwax transfer layer portion of the transferable substrate advantageously contains an oil which becomes activated upon application of heat to promote release of the transferable substrate from the carrier web to the article.

Abstract: PURPOSE: A method for forming a contact hole is to prevent an undoped oxide film, which is exposed when etching a doped oxide film, from being etched. CONSTITUTION: After a field oxide film(101) is formed on a silicon substrate(100), an insulating oxide film(1) is deposited on the field oxide film, and a bit line or capacitor(3) is formed on the insulating oxide film. After an undoped oxide film(2) of a thin thickness is deposited on the bit line or capacitor, a doped oxide film of a thick thickness is deposited on the undoped oxide film. A photoresist mask pattern(5) is formed on the doped oxide film, and the doped oxide film is isotropic-etched using an HF vapor of a low pressure. The residue doped oxide film and the undoped oxide film are etched to form a contact hole(10) exposing the substrate and the bit line or capacitor. When the doped oxide film is etched, a partial pressure is controlled to be below 500 Pascal.
