Method of determination of temperature and heat resistance of the points on the integrated circuit crystal surface

Abstract

Method for visualization of integrated circuit (IC) surface temperature by means of the liquid crystal film deposited from solution on its surface is proposed. The boundaries of local regions represent isotherms with corresponding phase transitions. On the base of isotherms positions and consumed by IC power thermal resistances between crystal and environment are determined.
