摘要:
A method of fabricating a high density electronic package is disclosed. The package (10) includes a module (12) of laminated semiconductor chips (14), including spare chip(s) and a supporting substrate (18) with a fixed interconnect pattern (20). Chip connection pads are provided at a first pad level of the module; one or more pads corresponding to each chip in the module (12). The module is tested at the first pad level to identify defective chip(s). A spare routing pattern is applied to the module for electrically isolating defective chip(s) and effectively substituting spare chip(s) therefor such that a predetermined pattern of metal interconnect landings (30) on an access surface of the module remains unchanged, as does the supporting substrate.

A resistor personalized memory cell c(MC) consisting of a resistive gate field effect transistor (2). One end of the gate electrode (5) is connected to the memory cell access line (WL2), the other end to one of its source or drain regions (3, 4). The source or drain region (3, 4) not connected to the gate electrode (5) is connected to the memory cell bit line (BL2). Memory cell personalization is accomplished by selecting the resistance of the resistive gate (5). Memory cell data is read by detecting the current flow through the cell, the magnitude of the current flow being proportional to the gate resistance.

An integrated memory cube structure and method of fabrication wherein stacked semiconductor memory chips are integrated by a controlling logic chip such that a more powerful memory architecture is defined with the functional appearance of a single, higher level memory chip. A memory/logic cube is formed having N memory chips and at least one logic chip, with each memory chip of the cube having M memory devices. The controlling logic chip coordinates external communication with the N memory chips such that a single memory chip architecture with N × M memory devices appears at the cube's I/O pins. A corresponding fabrication technique includes an approach for facilitating metallization patterning on the side surface of the memory subunit.

An integrated multichip memory module structure and method of fabrication wherein stacked semiconductor memory chips are integrated by a controlling logic chip such that a more powerful memory architecture is defined with the appearance of a single, higher level memory chip. A memory subunit is formed having N memory chips with each memory chip of the subunit having M memory devices. The controlling logic chip coordinates external communication with the N memory chips such that a single memory chip architecture with N × M memory devices appears at the module's I/O pins. A preformed electrical interface layer is employed at one end of the memory subunit to electrically interconnect the controlling logic chip with the memory chips comprising the subunit. The controlling logic chip has smaller dimensions than the dimensions of the memory chips comprising the subunit. A lead frame, having an inner opening extending therethrough, is secured to the electrical interface layer and the controlling logic chip is secured to the electrical interface layer so as to reside within the lead frame, thereby producing a dense multichip integrated circuit package. Corresponding fabrication techniques include an approach for facilitating metallization patterning on the side surface of the memory subunit.

A structure and method is disclosed for cooling a semiconductor computer chip module (21). The semiconductor computer chip module is made up of a plurality of semiconductor chips bonded together. In one aspect of the present invention every other chip is staggered such that recesses are formed between protruding edges of every other chip along two opposite faces of the chip module. The opposite faces with the staggered chips are capped and sealed so that coolant channels are formed between the recesses and the sealing caps. In another aspect, one face of the chip module is bonded by a plurality of connectors to a base (23). The base and chip module with connectors form a chamber (29). The chamber is sealed and an opening (31) is made in the base to circulate coolant into and around the connectors of the base and up along the coolant channels which are in fluid communication with the base. Thermal vias are provided between selected connectors and the chip module to conduct heat from the chips of the module to the connectors.
