Abstract:
A Silicon on Insulator (SOI) Integrated Circuit (IC) chip with devices such as a vertical Silicon Controlled Rectifier (SCR), vertical bipolar transistors, a vertical capacitor, a resistor and/or a vertical pinch resistor and method of making the device(s). The devices are formed in a seed hole through the SOI surface layer and insulator layer to the substrate. A buried diffusion, e.g., N-type, is formed through the seed hole in the substrate. A doped epitaxial layer is formed on the buried diffusion and may include multiple doped layers, e.g., a P-type layer and an N-type layer. Polysilicon, e.g., P-type, may be formed on the doped epitaxial layer. Contacts to the buried diffusion are formed in a contact liner.

Abstract:
Disclosed are embodiments of an e-fuse programming/re-programming circuit. In one embodiment, the e-fuse (150) has two short high atomic diffusion resistance conductor layers (110, 130) positioned on opposite sides (121, 122) and at a same end (123) of a long low atomic diffusion resistance conductor layer (120). A voltage source (170) is used to vary the polarity and, optionally, the magnitude of voltage applied to the terminals (first terminal = 170/161/110; second terminal = 170/162/130; third terminal = 170/163/proximate end 123 of conductor layer 120; and, fourth terminal = 170/164/distal end 124 of conductor layer 120) in order to control bi-directional flow of electrons within the long conductor layer and, thereby formation of opens and/or shorts at the long conductor layer-short conductor layer interfaces (125, 126). The formation of such opens and/or shorts can be used to achieve different programming states (11, 01, 10, 00). Other circuit structure embodiments incorporate e-fuses (650) with additional conductor layers and additional terminals so as to allow for even more programming states. Also disclosed are embodiments of associated e-fuse programming and re-programming methods.

A robust ESD protection circuit, method and design structure for tolerant and failsafe designs are disclosed. A circuit (200) includes a middle junction control circuit (250) that turns off a top NFET (225) of a stacked NFET electrostatic discharge (ESD) protection circuit (pad 215, ground 220, top NFET 225, bottom NFET 230, top resistor 235, and bottom resistor 240) during an ESD event.
Abstract:
Auf Manipulation reagierende Baugruppen werden bereitgestellt, die eine Leiterplatte, eine an der Leiterplatte angebrachte Gehäusebaugruppe und einen Drucksensor umfassen. Die Leiterplatte enthält eine elektronische Komponente, und die Gehäusebaugruppe ist so mit der Leiterplatte verbunden, dass sie die elektronische Komponente in einem sicheren Volumen einschließt. Die Gehäusebaugruppe umfasst ein Gehäuse mit einem abgedichteten Innenraum und ein Strukturmaterial innerhalb des abgedichteten Innenraums des Gehäuses. Das Strukturmaterial innerhalb des Gehäuses verhindert ein Verformen des Gehäuses aufgrund einer Druckdifferenz zwischen dem Druck des abgedichteten Innenraums und dem zumindest teilweisen Druck um das Gehäuse herum. Der Drucksensor erfasst den Druck im abgedichteten Innenraum des Gehäuses, um es zu ermöglichen, eine Druckänderung zu erkennen, die auf ein Manipulationsereignis hinweist.

Abstract:
Bi-directional back-to-back stacked SCRs for high-voltage pin ESD protection, methods of manufacture and design structures are provided. The device includes a symmetrical bi-directional back-to-back stacked silicon controlled rectifier (SCR). An anode (10a) of a first of the back-to-back stacked SCR (10) is connected to an input (30). An anode (20a) of a second of the back-to-back stacked SCR (20) is connected to ground (GND). Cathodes (10b, 20b) of the first and second of the back- to-back stacked SCR are connected together. Each of the symmetrical bi-directional back-to-back SCRs include a pair of diodes (Di, D2) directing current towards the cathodes which, upon application of a voltage, become reverse biased effectively deactivating elements from one of the symmetrical bi-directional back-to-back SCRs while the diodes (D3, D4) of another of the symmetrical bi-directional back-to-back SCRs direct current in the same direction as the reverse biased diodes.
