摘要:
A process for forming a photoresist pattern on a device, comprising; a) forming a layer of first photoresist on a substrate from a first photoresist composition; b) imagewise exposing the first photoresist; c) developing the first photoresist to form a first photoresist pattern; d) treating the first photoresist pattern with a hardening compound comprising at least 2 amino (NH2) groups, thereby forming a hardened first photoresist pattern; e) forming a second photoresist layer on the region of the substrate including the hardened first photoresist pattern from a second photoresist composition; f) flood exposing the second photoresist; and, g) developing the flood exposed second photoresist to form a photoresist pattern with increased dimensions and reduced spaces.

摘要:
A process for imaging a photoresist comprising the steps of, a) forming a stack of multiple layers of organic antireflective coatings on a substrate; b) forming a coating of a photoresist over the upper layer of the stack of multiple layers of organic antireflective coatings; c) imagewise exposing the photoresist with an exposure equipment; and, d) developing the coating with a developer.
摘要:
Techniques and systems for measuring absolute thickness, the total thickness variation, and electric resistivity of a semiconductor wafer in a nondestructive optical fashion. Optical absorption is used to measure the absolute thickness of a semiconductor wafer with a light source and a phototransceiver. The thickness is determined by comparing the amount of absorption to a calibrated amount. Coherent light interference is used to measure the total thickness variation of a substrate. Alternatively, both the absolute thickness and total thickness variation of the substrate can be measured based on light absorption using a CCD imaging device. The resistivity of a wafer sample can also be measured by using an alternating electrical signal.
