    摘要: A phase change resistor device has a phase change material (PCM) for which the phase transition occurs inside the PCM and not at the interface with a contact electrode. For ease of manufacturing the PCM is an elongate line structure (210, 215) surrounded by the conductive electrode portions (200, 240) at its lateral sides, and is formed in a CMOS backend process. An alternative is to form the device coupled directly to other circuit parts without the electrodes. In each case, there is a line of PCM which has a constant diameter or cross section, formed with reduced dimensions by using a spacer as a hard mask. The first contact electrode and the second contact electrode are electrically connected by a “one dimensional” layer of the PCM. The contact resistance between the one-dimensional layer of PCM and the first contact electrode at the second contact electrode is lower than the resistance of a central or intervening portion of the line.

    摘要: The invention relates to a method of photolithography comprising the steps of: providing a substrate and forming a layer of a photoresist on the substrate, performing a first exposure in which a predetermined part of the layer of photoresist is irradiated through a mask having a pattern for forming a latent image of said pattern in the layer of the photoresist, performing a pretreatment on the layer of the photoresist to remove a predetermined part of the latent image before performing the fixation. The method provides an improved process window. The invention further relates to a photoresist for use within the method of the invention.
