摘要： A vertical-current-flow resistive element (12) comprising a monolithic region (12) having a first portion (12a) and a second portion (12b) arranged on top of one another and formed by a single material. The first portion has a first resistivity, and the second portion (12b) has a second resistivity, lower than the first resistivity. To this aim, a monolithic region with a uniform resistivity and a height greater than at least one of the other dimensions is first formed; then the resistivity of the first portion (12a) is increased by introducing, from the top, species that form a prevalently covalent bond with the conductive material of the monolithic region, so that the concentration of said species becomes higher in the first portion (12a) than in the second portion (12b). Preferably, the conductive material is a binary or ternary alloy, chosen from among TiAl, TiSi 2 , Ta, WSi, and the increase in resistivity is obtained by nitridation.

摘要： A dual resistance heater (24) for a phase change material region (28) is formed by depositing a resistive material. The heater material is then exposed to an implantation or plasma which increases the resistance of the surface (26) of the heater material relative to the remainder (27) of the heater material. As a result, the portion (26) of the heater material approximate to the phase change material region (28) is a highly effective heater because of its high resistance, but the bulk (27) of the heater material is not as resistive and, thus, does not increase the voltage drop and the current usage of the device.
